+The Fuck tries to match a rule for the previous command, creates a new command
+using the matched rule and runs it. Rules enabled by default are as follows:
 
-* `brew_unknown_command` – fixes wrong brew commands, for example `brew docto/brew doctor`;
-* `cd_parent` – changes `cd..` to `cd ..`;
+* `cd_correction` – spellchecks and correct failed cd commands;
 * `cd_mkdir` – creates directories before cd'ing into them;
+* `cd_parent` – changes `cd..` to `cd ..`;
+* `composer_not_command` – fixes composer command name;
 * `cp_omitting_directory` – adds `-a` when you `cp` directory;
+* `cpp11` – add missing `-std=c++11` to `g++` or `clang++`;
+* `dry` – fix repetitions like "git git push";
 * `fix_alt_space` – replaces Alt+Space with Space character;
+* `git_add` – fix *"Did you forget to 'git add'?"*;
+* `git_checkout` – creates the branch before checking-out;
 * `git_no_command` – fixes wrong git commands like `git brnch`;
+* `git_pull` – sets upstream before executing previous `git pull`;
 * `git_push` – adds `--set-upstream origin $branch` to previous failed `git push`;
+* `git_stash` – stashes you local modifications before rebasing or switching branch;
+* `grep_recursive` – adds `-r` when you trying to grep directory; 
 * `has_exists_script` – prepends `./` when script/binary exists;
 * `lein_not_task` – fixes wrong `lein` tasks like `lein rpl`;
+* `ls_lah` – adds -lah to ls;
+* `man_no_space` – fixes man commands without spaces, for example `mandiff`;
 * `mkdir_p` – adds `-p` when you trying to create directory without parent;
 * `no_command` – fixes wrong console commands, for example `vom/vim`;
+* `no_such_file` – creates missing directories with `mv` and `cp` commands;
 * `pip_unknown_command` – fixes wrong pip commands, for example `pip instatl/pip install`;
 * `python_command` – prepends `python` when you trying to run not executable/without `./` python script;
-* `sl_ls` – changes `sl` to `ls`;
 * `rm_dir` – adds `-rf` when you trying to remove directory;
+* `sl_ls` – changes `sl` to `ls`;
 * `ssh_known_hosts` – removes host from `known_hosts` on warning;
 * `sudo` – prepends `sudo` to previous command if it failed because of permissions;
 * `switch_layout` – switches command from your local layout to en;
+* `whois` – fixes `whois` command.
+
+Enabled by default only on specific platforms:
+
 * `apt_get` – installs app from apt if it not installed;
 * `brew_install` – fixes formula name for `brew install`;
-* `composer_not_command` – fixes composer command name.
+* `brew_unknown_command` – fixes wrong brew commands, for example `brew docto/brew doctor`;
+* `pacman` – installs app with `pacman` or `yaourt` if it is not installed.
 
 Bundled, but not enabled by default:
 
-* `ls_lah` – adds -lah to ls;
 * `rm_root` – adds `--no-preserve-root` to `rm -rf /` command.
