+## Description
 cool-retro-term is a terminal emulator which mimics the look and feel of the old cathode tube screens.
 It has been designed to be eye-candy, customizable, and reasonably lightweight.
 
-It uses the Konsole engine which is powerful and mature.
+It uses the QML port of qtermwidget (Konsole): https://github.com/Swordfish90/qmltermwidget.
 
-This terminal emulator requires Qt 5.2 or higher to run.
+This terminal emulator works under Linux and macOS and requires Qt5. It's suggested that you stick to the latest LTS version.

+Settings such as colors, fonts, and effects can be accessed via context menu.
 
-##Get cool-retro-term
-You can either build cool-retro-term yourself (see below) or walk the easy way and install one of these packages:

-Users of Fedora and openSUSE can grab a package from [Open Build Service](http://software.opensuse.org/package/cool-retro-term).
+## Install
 
-Arch users can install this [package](https://aur.archlinux.org/packages/cool-retro-term-git/) directly via the [AUR](https://aur.archlinux.org):
+If you want to get a hold of the latest version, just go to the Releases page and grab the latest AppImage (Linux) or dmg (macOS).
 
-    yaourt -S aur/cool-retro-term-git
+Alternatively, most distributions such as Ubuntu, Fedora or Arch already package cool-retro-term in their official repositories.

-
----
-
-**Fedora**
-This command should install the known fedora dependencies:
-
-    sudo yum -y install qt5-qtbase qt5-qtbase-devel qt5-qtdeclarative qt5-qtdeclarative-devel qt5-qtgraphicaleffects qt5-qtquickcontrols
-
-or:

-
----
-
-**Arch Linux**
-
-    sudo pacman -S qt5-base qt5-declarative qt5-quickcontrols qt5-graphicaleffects
-    
----
-
-**openSUSE**
-
-Add repository with latest Qt 5 (this is only needed on openSUSE 13.1, Factory already has it):
-
-    sudo zypper ar http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_13.1/ KDE:Qt5
-
-Install dependencies:
-
-    sudo zypper install libqt5-qtbase-devel libqt5-qtdeclarative-devel libqt5-qtquickcontrols libqt5-qtgraphicaleffects
-
----
-
-**Anyone else**
-
-Install Qt directly from here http://qt-project.org/downloads . Once done export them in you path (replace "_/opt/Qt5.3.1/5.3/gcc_64/bin_" with your correct folder):
-    
-    export PATH=/opt/Qt5.3.1/5.3/gcc_64/bin/:$PATH
----
-
-###Compile
-Once you installed all dependencies (Qt is installed and in your path) you need to compile and run the application: 
-
-```bash
-# Get it from GitHub
-git clone https://github.com/Swordfish90/cool-retro-term.git
-
-# Build it
-cd cool-retro-term
-
-# Compile (Fedora and OpenSUSE user should use qmake-qt5 instead of qmake)
-qmake && make
-
-# Have fun!
-./cool-retro-term
-```
-
-##Build instructions (OSX)
-
-    brew install qt5
-    git clone https://github.com/Swordfish90/cool-retro-term.git
-    export CPPFLAGS="-I/usr/local/opt/qt5/include"
-    export LDFLAGS="-L/usr/local/opt/qt5/lib"
-    export PATH=/usr/local/opt/qt5/bin:$PATH

-3270font: A font for the nostalgic
-==================================
-https://github.com/rbanffy/3270font
-
-![Screenshot](https://raw.github.com/wiki/rbanffy/3270font/emacs.png)
-
-A little bit of history
------------------------
-
-This font is derived from the x3270 font, which, in turn, was translated
-from the one in Georgia Tech's 3270tool, which was itself hand-copied
-from a 3270 terminal. I built it because I felt terminals deserve to be
-pretty. The .sfd font file contains a x3270 bitmap font that was used
-for guidance.
-
-![Using with the Cathode terminal program]
-(https://raw.github.com/wiki/rbanffy/3270font/cathode.png)
-
-The format
-----------
-
-This font was built with FontForge. You'll need it if you want to
-generate fonts for your platform. On most civilized operating systems,
-you can simply `apt-get install fontforge`, `yum install fontforge` or
-even `port install fontforge`. On others, you may need to grab your copy
-from http://fontforge.org/. I encourage you to drop by and read the
-tutorials.
-
-![Powerline-shell compatible!]
-(https://raw.github.com/wiki/rbanffy/3270font/powerline.png)
-
-Adobe Type 1, TTF, OTF and WOFF versions are available for download on
-http://s3.amazonaws.com/rbanffy/3270_fonts.zip for those who would just
-like to use them.
-
-![Using it on OSX]
-(https://raw.github.com/wiki/rbanffy/3270font/osx_terminal.png)
-
-Generating derived files
-------------------------
-
-The script `generate_derived.pe` calls FontForge and generates
-PostScript, OTF, TTF and WOFF versions of the base font, as well as a 
-slightly more condensed .sfd file with the base font narrowed to 488 
-units, with no glyph rescaling and its corresponding PostScript, TTF, 
-OTF and WOFF versions.
-
-Contributing
-------------
-
-I don't think GitHub's pull-request mechanism is FontForge-friendly. If
-you want to contribute (there are a lot of missing glyphs, such as the
-APL set and most non-latin alphabets which most likely were never built
-into 3270 terminals), get in touch and we will figure out how to do it
-right.
-
-Preserving history
-------------------
-
-I regard the history of electronic computing a very important part of
-our civilization's history. Consider donating to entities that help
-preserve it, such as the Computer History Museum
-(http://www.computerhistory.org/), the IT History Society
-(http://ithistory.org/) and many others around the world. If you have a
-historically significant piece of technology in your closet or garage,
-consider contacting a local technology or industrial-design-oriented
-museum for advice.
-
-Known problems
---------------
-
-I have received errors when installing the OTF, TTF, and PFM fonts on
-Windows 7 and 8 (didn't try others).

-\deflang1033\pard\plain\f2\fs24\cf1 Atari Classic TrueType Fonts \plain\f2\fs24\cf0 
-\par \plain\f4\fs16\cf0 (Windows Version 1.1)
-\par Created by Mark Simonson (v.1.0-1998, v.1.1-2001)
-\par marksim@bitstream.net
-\par Website: Mac/Atari Fusion--Atari Home Computer Resources for Mac Users
-\par http://www2.bitstream.net/~marksim/atarimac/
-\par Macintosh version also available.
-\par 
-\par With these fonts installed, you can view and print Atari text files in any text editor that allows you to change fonts (WordPad, for example). Tip: In order to get the correct line breaks, you will need to change the ATASCII return character (155) to the DOS LF character. (In the Character Map accessory, the ATASCII return is the blank character that comes just before the inverse up-arrow.)
-\par 
-\par There are three different fonts. \plain\f4\fs16\cf0\b Atari Classic Chunky \plain\f4\fs16\cf0 is a pixel-for-pixel copy of the original ATASCII character set. \plain\f4\fs16\cf0\b Atari Classic Smooth \plain\f4\fs16\cf0 interprets the pixel aliasing (stair steps) as diagonal lines. \plain\f4\fs16\cf0\b Atari Classic Extrasmooth \plain\f4\fs16\cf0 refines this idea further with the addition of curves. \plain\f4\fs16\cf0\b Smooth\plain\f4\fs16\cf0  and \plain\f4\fs16\cf0\b Extrasmooth\plain\f4\fs16\cf0  were designed for better appearance and legibility at larger sizes and on print-outs. Use the one that looks best to you.
-\par 
-\par These fonts will tend to look uneven at font sizes that do not correspond to the 8-by-8 pixel grid that the characters are based on. Because Windows assumes 96ppi screen resolution, they will look best in a font size that is a multiple of 6 (i.e., 6pt, 12pt, 18pt, etc.). (In Windows, 6 points = 8 pixels.)
-\par 
-\par The Atari Classic TrueType fonts duplicate the ATASCII character set on a low-level basis. Unlike a normal Windows font, ATASCII utilizes all character codes from $00 to $FF (0 to 255). The lower half are normal characters; the upper half are inverse versions of the lower half. The basic ASCII characters ($00 to $7F) correspond fairly closely except for the first 32, which don't normally contain characters in a Windows font.
-\par 
-\par Due to differences between the way Windows and the Atari use character codes, not all characters will display properly in Windows. In fact, some characters will not display at all (though they do exist in the font). Unfortunately, this is due to certain character codes being reserved in Windows and there doesn't appear to be any way to work around it. The character codes affected are: $00-$1F (0-31), $7F-$81 (127-129), $8D-$90 (141-144), $9D (157), and $9F (158).
-\par 
-\par Not all characters can be typed from the keyboard. You can however copy characters as needed from this document (see tables below). The Character Map desk accessory can help also.
-\par 
-\par \plain\f4\fs16\cf0\b ATASCII CHARACTER SET TABLES
-\par \plain\f4\fs16\cf0 
-\par In order to see the ATASCII character set with these tables, the Atari Classic TrueType fonts must be installed. Characters that are not displayed properly are due to character code usage differences between ATASCII and Windows (see above).

->> perfect dos vga 437 - general information  >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
--------------------------------------------------------------------------------
-
- "Perfect DOS VGA 437" and "Perfect DOS VGA 437 Win" are truetype fonts
- designed to emulate the MS-DOS/Text mode standard font, used on VGA monitors,
- with the 437 Codepage (standard US/International). This is a "bitmap" font,
- meaning it emulates a bitmap font and can only be used at a given size (8 or
- multiples of it like 16, 24, 32, etc). It's optimized for Flash too, so it
- won't produce antialias if used at round positions.
- 
- There are two fonts available. "Perfect DOS VGA 437" uses the original DOS
- codepage 437. It should be used, for example, if you're opening DOS ASCII
- files on notepad or another windows-based editor. Since it's faithful to the
- original DOS codes, it won't accent correctly in windows ("é" would produce
- something different, not an "e" with an acute).
- 
- There's also "Perfect DOS VGA 437 Win" which is the exactly same font adapted
- to a windows codepage. This should use accented characters correctly but won't
- work if you're opening a DOS-based text file.
- 
- UPDATE: this is a new version, updated in august/2008. It has fixed leading
- metrics for Mac systems.
-
--------------------------------------------------------------------------------
->> perfect dos vga 437 - creation process >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
--------------------------------------------------------------------------------
- 
- This font was created to be used on a Flash-based ANSi viewer I'm working. To
- create it, I created a small Quick Basic program to write all characters on
- screen,
- 
-  CLS
-  FOR l = 0 TO 255
-    charWrite 1 + (l MOD 20), 1 + (l \ 20) * 6 + (l MOD 2), LTRIM$(RTRIM$(STR$(l))) + CHR$(l)
-  NEXT
-  SUB charWrite (lin, col, char$)
-    DEF SEG = &HB800
-    FOR i = 1 TO LEN(char$)
-      POKE ((lin - 1) * 160) + ((col - 2 + i) * 2), ASC(MID$(char$, i, 1))
-      IF (i = LEN(char$)) THEN POKE ((lin - 1) * 160) + ((col - 2 + i) * 2) + 1, 113
-    NEXT
-  END SUB
-  
- Then captured the text screen using SCREEN THIEF (a very, very old screen
- capture TSR program which converts text screens to images accurately). I then
- recreated the font polygon by polygon on Fontlab, while looking at the image
- on Photoshop. No conversion took place.

+Creative Commons Corporation ("Creative Commons") is not a law firm and
+does not provide legal services or legal advice. Distribution of
+Creative Commons public licenses does not create a lawyer-client or

+
+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or
+     limitation to copyright. More considerations for licensors:
+	wiki.creativecommons.org/Considerations_for_licensors
+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to
+     copyright--then that use is not regulated by the license. Our
+     licenses grant only permissions under copyright and certain
+     other rights that a licensor has authority to grant. Use of
+     the licensed material may still be restricted for other
+     reasons, including because others have copyright or other
+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More_considerations

+License
+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution-ShareAlike 4.0 International Public License ("Public
+License"). To the extent this Public License may be interpreted as a

+     Rights.
+
+  e. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright

+     License.
+
+  i. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  j. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.

+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  l. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of

+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  m. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+  b. ShareAlike.
+
+     In addition to the conditions in Section 3(a), if You Share
+     Adapted Material You produce, the following conditions also apply.
+
+       1. The Adapter's License You apply must be a Creative Commons
+          license with the same License Elements, this version or
+          later, or a BY-SA Compatible License.
+
+       2. You must include the text of, or the URI or hyperlink to, the
+          Adapter's License You apply. You may satisfy this condition
+          in any reasonable manner based on the medium, means, and
+          context in which You Share Adapted Material.
+
+       3. You may not offer or impose any additional or different terms
+          or conditions on, or apply any Effective Technological
+          Measures to, Adapted Material that restrict exercise of the
+          rights granted under the Adapter's License You apply.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material,
+
+     including for purposes of Section 3(b); and
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+3270font: A font for the nostalgic
+==================================
+
+![Travis-CI](https://api.travis-ci.org/rbanffy/3270font.svg)
+
+![Screenshot](https://raw.githubusercontent.com/wiki/rbanffy/3270font/emacs.png)
+
+![Sample](https://raw.githubusercontent.com/wiki/rbanffy/3270font/3270Medium_sample.png)
+
+A little bit of history
+-----------------------
+
+This font is derived from the x3270 font, which, in turn, was
+translated from the one in Georgia Tech's 3270tool, which was itself
+hand-copied from a 3270 series terminal. I built it because I felt
+terminals deserve to be pretty. The .sfd font file contains a x3270
+bitmap font that was used for guidance.
+
+![Using with the cool-old-tern (now cool-retro-term) terminal program](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/cool-retro-term.png)
+
+Getting it
+----------
+
+If you are running Debian or Ubuntu and you don't want to mess with
+building your font files, you can simply `apt-get install fonts-3270`
+(It's available from the Debian
+(https://packages.debian.org/sid/fonts/fonts-3270) and Ubuntu
+(http://packages.ubuntu.com/zesty/fonts-3270) package repos at
+https://packages.debian.org/sid/fonts/fonts-3270 and
+http://packages.ubuntu.com/xenial/fonts/fonts-3270, although the
+packaged version may not be the latest version, but it's good enough for
+most purposes. For those who don't have the luxury of a proper
+system-managed package, Adobe Type 1, TTF, OTF and WOFF versions are
+available for download on
+http://s3.amazonaws.com/3270font/3270_fonts_4cfe95c.zip (although this
+URL may not always reflect the latest version).
+
+![ASCII is so 60's](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/cyrillic.png)
+
+The format
+----------
+
+The "source" file is edited using FontForge. You'll need it if you want
+to generate fonts for your platform. On most civilized operating
+systems, you can simply `apt-get install fontforge`, `yum install
+fontforge` or even `port install fontforge`. On others, you may need to
+grab your copy from http://fontforge.org/. I encourage you to drop by
+and read the tutorials.
+
+![Powerline-shell compatible!](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/powerline.png)
+
+![Using it on OSX (don't forget to turn antialiasing on)](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/osx_terminal.png)
+
+If you are running Windows, you'll probably need something like
+Cygwin, but, in the end, the font works correctly (with some very
+minor hinting issues).
+
+![Works on Windows](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/windows_7.png)
+
+Generating usable font files
+----------------------------
+
+The easiest way to generate the font files your computer can use is to
+run `make all` (if you are running Ubuntu or Debian, `make install` will
+install them too). Using `make help` will offer a handy list of options.
+
+The script `generate_derived.pe` calls FontForge and generates
+PostScript, OTF, TTF and WOFF versions of the base font, as well as a
+slightly more condensed .sfd file with the base font narrowed to 488
+units, with no glyph rescaling (or cropping - we need to fix that) and
+its corresponding PostScript, TTF, OTF and WOFF versions.
+
+![For your favorite editor](
+https://raw.githubusercontent.com/wiki/rbanffy/3270font/symbols.png)
+
+Contributing
+------------
+
+I fear GitHub's pull-request mechanism may not be very
+FontForge-friendly. If you want to contribute (there are a lot of
+missing glyphs, such as most non-latin alphabets which most likely were
+never built into 3270 terminals), the best workflow would probably be to
+add the encoding slots (if needed), add/make the changes, remove the
+unchanged glyphs and save it as a different file. If, in doubt, get in
+touch and we will figure out how to do it right.
+
+In order to generate the sample image and the grids for FontForge,
+you'll need a Python 3 environment with PIL or pillow installed. The
+requirements.txt file lists everything you need to do it.
+
+Known problems
+--------------
+
+Not all symbols in the 3270 charset have Unicode counterparts. When
+possible, they are duplicated in the Unicode space. The 3270-only
+symbols are at the end of the font, along with some glyphs useful for
+building others.
+
+Please refer to http://x3270.bgp.nu/Charset.html for a complete map.
+
+Future improvements
+-------------------
+
+A grid generator is provided for producing various grid sizes for the
+font. Those grids are not used yet, but they are intended to be used to
+align font features to provide better rendering at common font size
+choices. The captures below exemplify these choices:
