+# 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.

+   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
