 ## Requirements
 
-- python (2.7+ or 3.3+)
+- python (3.4+)
 - pip
 - python-dev
 
 ## Installation
 
-Install `The Fuck` with `pip`:
+On OS X, you can install *The Fuck* via [Homebrew][homebrew] (or via [Linuxbrew][linuxbrew] on Linux):
 
 ```bash
-sudo pip install thefuck
+brew install thefuck
 ```
 
-[Or using an OS package manager (OS X, Ubuntu, Arch).](https://github.com/nvbn/thefuck/wiki/Installation)
+On Ubuntu / Mint, install *The Fuck* with the following commands:
+```bash
+sudo apt update
+sudo apt install python3-dev python3-pip python3-setuptools
+sudo pip3 install thefuck
+```
 
-And add to the `.bashrc` or `.bash_profile`(for OSX):
+On FreeBSD, install *The Fuck* with the following commands:
+```bash
+pkg install thefuck
+```
+
+On ChromeOS, install *The Fuck* using [chromebrew](https://github.com/skycocker/chromebrew) with the following command:
+```bash
+crew install thefuck
+```
+
+On other systems, install *The Fuck*  by using `pip`:
 
 ```bash
-alias fuck='eval $(thefuck $(fc -ln -1)); history -r'
+pip install thefuck
+```
+
+[Alternatively, you may use an OS package manager (OS X, Ubuntu, Arch).](https://github.com/nvbn/thefuck/wiki/Installation)
+
+<a href='#manual-installation' name='manual-installation'>#</a>
+It is recommended that you place this command in your `.bash_profile`,
+`.bashrc`, `.zshrc` or other startup script:
+
+```bash
+eval $(thefuck --alias)
 # You can use whatever you want as an alias, like for Mondays:
-alias FUCK='fuck'
+eval $(thefuck --alias FUCK)
 ```
 
-Or in your `.zshrc`:
+[Or in your shell config (Bash, Zsh, Fish, Powershell, tcsh).](https://github.com/nvbn/thefuck/wiki/Shell-aliases)
+
+Changes are only available in a new shell session. To make changes immediately
+available, run `source ~/.bashrc` (or your shell config file like `.zshrc`).
+
+To run fixed commands without confirmation, use the `--yeah` option (or just `-y` for short, or `--hard` if you're especially frustrated):
 
 ```bash
-alias fuck='eval $(thefuck $(fc -ln -1 | tail -n 1)); fc -R'
+fuck --yeah
 ```
 
-If you are using `tcsh`:
-```tcsh
-alias fuck 'set fucked_cmd=`history -h 2 | head -n 1` && eval `thefuck ${fucked_cmd}`'
-```
-
-Alternatively, you can redirect the output of `thefuck-alias`:
+To fix commands recursively until succeeding, use the `-r` option:
 
 ```bash
-thefuck-alias >> ~/.bashrc
+fuck -r
 ```
 
-[Or in your shell config (Bash, Zsh, Fish, Powershell).](https://github.com/nvbn/thefuck/wiki/Shell-aliases)
-
-Changes will be available only in a new shell session.
-To make them available immediately, run `source ~/.bashrc` (or your shell config file like `.zshrc`).

-## Update
+## Updating
 
 ```bash
-sudo pip install thefuck --upgrade
+pip3 install thefuck --upgrade

+**Note: Alias functionality was changed in v1.34 of *The Fuck***

 ## Creating your own rules
 
-For adding your own rule you should create `your-rule-name.py`
-in `~/.thefuck/rules`. Rule should contain two functions:
-`match(command: Command, settings: Settings) -> bool`
-and `get_new_command(command: Command, settings: Settings) -> str`.
-Also the rule can contain optional function
-`side_effect(command: Command, settings: Settings) -> None` and
-optional boolean `enabled_by_default`
-
-`Command` has three attributes: `script`, `stdout` and `stderr`.
-
-`Settings` is a special object filled with `~/.thefuck/settings.py` and values from env, [more](#settings).
-
-Simple example of the rule for running script with `sudo`:
+To add your own rule, create a file named `your-rule-name.py`
+in `~/.config/thefuck/rules`. The rule file must contain two functions:
 
 ```python
-def match(command, settings):
-    return ('permission denied' in command.stderr.lower()
-            or 'EACCES' in command.stderr)
+match(command: Command) -> bool
+get_new_command(command: Command) -> str | list[str]
+```
+
+Additionally, rules can contain optional functions:
+
+```python
+side_effect(old_command: Command, fixed_command: str) -> None
+```
+Rules can also contain the optional variables `enabled_by_default`, `requires_output` and `priority`.
+
+`Command` has three attributes: `script`, `output` and `script_parts`.
+Your rule should not change `Command`.
 
 
-def get_new_command(command, settings):
+**Rules api changed in 3.0:** To access a rule's settings, import it with
+ `from thefuck.conf import settings`
+
+`settings` is a special object assembled from `~/.config/thefuck/settings.py`,
+and values from env ([see more below](#settings)).
+
+A simple example rule for running a script with `sudo`:
+
+```python
+def match(command):
+    return ('permission denied' in command.output.lower()
+            or 'EACCES' in command.output)
+
+
+def get_new_command(command):
     return 'sudo {}'.format(command.script)
 
 # Optional:
 enabled_by_default = True
 
-def side_effect(command, settings):
+def side_effect(command, fixed_command):
     subprocess.call('chmod 777 .', shell=True)
 
-priority = 1000  # Lower first
+priority = 1000  # Lower first, default is 1000
+
+requires_output = True
 ```

+[app/os-specific helpers](https://github.com/nvbn/thefuck/tree/master/thefuck/specific/).
 
 ## Settings
 
-The Fuck has a few settings parameters which can be changed in `~/.thefuck/settings.py`:
+Several *The Fuck* parameters can be changed in the file `$XDG_CONFIG_HOME/thefuck/settings.py`
+(`$XDG_CONFIG_HOME` defaults to `~/.config`):
 
-* `rules` &ndash; list of enabled rules, by default `thefuck.conf.DEFAULT_RULES`;
-* `require_confirmation` &ndash; requires confirmation before running new command, by default `False`;
+* `rules` &ndash; list of enabled rules, by default `thefuck.const.DEFAULT_RULES`;
+* `exclude_rules` &ndash; list of disabled rules, by default `[]`;
+* `require_confirmation` &ndash; requires confirmation before running new command, by default `True`;
 * `wait_command` &ndash; max amount of time in seconds for getting previous command output;
 * `no_colors` &ndash; disable colored output;
-* `priority` &ndash; dict with rules priorities, rule with lower `priority` will be matched first.
+* `priority` &ndash; dict with rules priorities, rule with lower `priority` will be matched first;
+* `debug` &ndash; enables debug output, by default `False`;
+* `history_limit` &ndash; numeric value of how many history commands will be scanned, like `2000`;
+* `alter_history` &ndash; push fixed command to history, by default `True`;
+* `wait_slow_command` &ndash; max amount of time in seconds for getting previous command output if it in `slow_commands` list;
+* `slow_commands` &ndash; list of slow commands;
+* `num_close_matches` &ndash; maximum number of close matches to suggest, by default `3`.
 
-Example of `settings.py`:
+An example of `settings.py`:
 
 ```python
 rules = ['sudo', 'no_command']
+exclude_rules = ['git_push']
 require_confirmation = True
 wait_command = 10
 no_colors = False
 priority = {'sudo': 100, 'no_command': 9999}
+debug = False
+history_limit = 9999
+wait_slow_command = 20
+slow_commands = ['react-native', 'gradle']
+num_close_matches = 5
 ```
 
 Or via environment variables:
 
 * `THEFUCK_RULES` &ndash; list of enabled rules, like `DEFAULT_RULES:rm_root` or `sudo:no_command`;
+* `THEFUCK_EXCLUDE_RULES` &ndash; list of disabled rules, like `git_pull:git_push`;
 * `THEFUCK_REQUIRE_CONFIRMATION` &ndash; require confirmation before running new command, `true/false`;
 * `THEFUCK_WAIT_COMMAND` &ndash; max amount of time in seconds for getting previous command output;
 * `THEFUCK_NO_COLORS` &ndash; disable colored output, `true/false`;
 * `THEFUCK_PRIORITY` &ndash; priority of the rules, like `no_command=9999:apt_get=100`,
-rule with lower `priority` will be matched first.
+rule with lower `priority` will be matched first;
+* `THEFUCK_DEBUG` &ndash; enables debug output, `true/false`;
+* `THEFUCK_HISTORY_LIMIT` &ndash; how many history commands will be scanned, like `2000`;
+* `THEFUCK_ALTER_HISTORY` &ndash; push fixed command to history `true/false`;
+* `THEFUCK_WAIT_SLOW_COMMAND` &ndash; max amount of time in seconds for getting previous command output if it in `slow_commands` list;
+* `THEFUCK_SLOW_COMMANDS` &ndash; list of slow commands, like `lein:gradle`;
+* `THEFUCK_NUM_CLOSE_MATCHES` &ndash; maximum number of close matches to suggest, like `5`.
 
 For example:
 
 ```bash
 export THEFUCK_RULES='sudo:no_command'
+export THEFUCK_EXCLUDE_RULES='git_pull:git_push'
 export THEFUCK_REQUIRE_CONFIRMATION='true'
 export THEFUCK_WAIT_COMMAND=10
 export THEFUCK_NO_COLORS='false'
 export THEFUCK_PRIORITY='no_command=9999:apt_get=100'
+export THEFUCK_HISTORY_LIMIT='2000'
+export THEFUCK_NUM_CLOSE_MATCHES='5'
+```
+
+## Third-party packages with rules
+
+If you'd like to make a specific set of non-public rules, but would still like
+to share them with others, create a package named `thefuck_contrib_*` with
+the following structure:
+
+```
+thefuck_contrib_foo
+  thefuck_contrib_foo
+    rules
+      __init__.py
+      *third-party rules*
+    __init__.py
+    *third-party-utils*
+  setup.py
+```
+
+*The Fuck* will find rules located in the `rules` module.
+
+## Experimental instant mode
+
+The default behavior of *The Fuck* requires time to re-run previous commands.
+When in instant mode, *The Fuck* saves time by logging output with [script](https://en.wikipedia.org/wiki/Script_(Unix)),
+then reading the log.
+
+[![gif with instant mode][instant-mode-gif-link]][instant-mode-gif-link]
+
+Currently, instant mode only supports Python 3 with bash or zsh. zsh's autocorrect function also needs to be disabled in order for thefuck to work properly.
+
+To enable instant mode, add `--enable-experimental-instant-mode`
+to the alias initialization in `.bashrc`, `.bash_profile` or `.zshrc`.
+
+For example:
+
+```bash
+eval $(thefuck --alias --enable-experimental-instant-mode)
 ```
