+# Report issues
+If you have any issue with The Fuck, sorry about that, but we will do what we
+can to fix that. Actually, maybe we already have, so first thing to do is to
+update The Fuck and see if the bug is still there.
+
+If it is (sorry again), check if the problem has not already been reported and
+if not, just open an issue on [GitHub](https://github.com/nvbn/thefuck) with
+the following basic information:
+  - the output of `thefuck --version` (something like `The Fuck 3.1 using
+    Python 3.5.0`);
+  - your shell and its version (`bash`, `zsh`, *Windows PowerShell*, etc.);
+  - your system (Debian 7, ArchLinux, Windows, etc.);
+  - how to reproduce the bug;
+  - the output of The Fuck with `THEFUCK_DEBUG=true` exported (typically execute
+    `export THEFUCK_DEBUG=true` in your shell before The Fuck);
+  - if the bug only appears with a specific application, the output of that
+    application and its version;
+  - anything else you think is relevant.
+
+It's only with enough information that we can do something to fix the problem.
+
+# Make a pull request
+We gladly accept pull request on the [official
+repository](https://github.com/nvbn/thefuck) for new rules, new features, bug
+fixes, etc.

 ## 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`.
+in `~/.config/thefuck/rules`. The rule should contain two functions:
+
+```python
+match(command: Command) -> bool
+get_new_command(command: Command) -> str | list[str]
+```
+
+Also the rule can contain an optional function
+
+```python
+side_effect(old_command: Command, fixed_command: str) -> None
+```
+and optional `enabled_by_default`, `requires_output` and `priority` variables.
 
 `Command` has three attributes: `script`, `stdout` and `stderr`.
 
-`Settings` is `~/.thefuck/settings.py`.
+*Rules api changed in 3.0:* For accessing settings in rule you need to import it with `from thefuck.conf import settings`.
+`settings` is a special object filled with `~/.config/thefuck/settings.py` and values from env ([see more below](#settings)).
 
 Simple example of the rule for running script with `sudo`:
 
 ```python
-def match(command, settings):
+def match(command):
     return ('permission denied' in command.stderr.lower()
             or 'EACCES' in command.stderr)
 
 
-def get_new_command(command, settings):
+def get_new_command(command):
     return 'sudo {}'.format(command.script)
+
+# Optional:
+enabled_by_default = True
+
+def side_effect(command, fixed_command):
+    subprocess.call('chmod 777 .', shell=True)
+
+priority = 1000  # Lower first, default is 1000
+
+requires_output = True
 ```

-* `require_confirmation` &ndash; require confirmation before running new command, by default `False`; 
-* `wait_command` &ndash; max amount of time in seconds for getting previous command output.

+* `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`;

+* `wait_slow_command` &ndash; max amount of time in seconds for getting previous command output if it in `slow_commands` list;

+
+apt-get is a simple command line interface for downloading and
+installing packages. The most frequently used commands are update
+and install.
+
+Commands:
+   update - Retrieve new lists of packages
+   upgrade - Perform an upgrade
+   install - Install new packages (pkg is libc6 not libc6.deb)
+   remove - Remove packages
+   autoremove - Remove automatically all unused packages
+   purge - Remove packages and config files
+   source - Download source archives
+   build-dep - Configure build-dependencies for source packages
+   dist-upgrade - Distribution upgrade, see apt-get(8)
+   dselect-upgrade - Follow dselect selections
+   clean - Erase downloaded archive files
+   autoclean - Erase old downloaded archive files
+   check - Verify that there are no broken dependencies
+   changelog - Download and display the changelog for the given package
+   download - Download the binary package into the current directory
+
+Options:
+  -h  This help text.
+  -q  Loggable output - no progress indicator
+  -qq No output except for errors
+  -d  Download only - do NOT install or unpack archives
+  -s  No-act. Perform ordering simulation
+  -y  Assume Yes to all queries and do not prompt
+  -f  Attempt to correct a system with broken dependencies in place
+  -m  Attempt to continue if archives are unlocatable
+  -u  Show a list of upgraded packages as well
+  -b  Build the source package after fetching it
+  -V  Show verbose version numbers
+  -c=? Read this configuration file
+  -o=? Set an arbitrary configuration option, eg -o dir::cache=/tmp
+See the apt-get(8), sources.list(5) and apt.conf(5) manual
+pages for more information and options.
+                       This APT has Super Cow Powers.
