 Prelude. It also adds an additional keymap that binds many of those
 extensions to keybindings.
 
+### Keymap
+
+#### Global
+
+* `C-M-h` - `backward-kill-word` (as in Bash/Zsh)
+* `C-x \` - `align-regexp`
+* `C-+` - `text-scale-increase`
+* `C--` - `text-scale-decrease`
+* `C-x O` - return you to the previous window (the inverse of `other-window` (`C-x o`))
+* `C-x ^` - `join-line`
+* `C-x p` - `proced` (manage processes form Emacs, works only in Linux)
+* `C-x m` - start eshell
+* `C-x M-m` - start your default shell
+* `C-x C-m` - sames as `M-x`
+* `C-h A` - `apropos` (search in all Emacs symbols)
+* `M-\` - `hippie-expand` (a replacement for the default `dabbrev-expand`)
+* `C-x C-b` - `ibuffer` (a replacement for the default `buffer-list`)
+* `F12` - toggle the Emacs menu bar
+* `C-x g` - open Magit's status buffer
+* `C-=` - `expand-region` (incremental text selection)
+
+#### Prelude Mode
+
+* `C-c o` - open the currently visited file with external program
+* `C-c g` - search in Google for the thing under point (or an interactive query)
+* `shift+return` - insert an empty line and indent it properly (as in most IDEs)
+* `control+shift+up` - move the current line up
+* `control+shift+down` - move the current line down
+* `C-c n` - fix indentation in buffer and strip whitespace
+* `C-c f` - open recently visitted file
+* `C-M-\` - indent region (if selected) or the entire buffer
+* `C-c u` - open URL in your default browser
+* `C-c e` - eval a bit of Emacs Lisp code and replace it with its result
+* `C-c s` - swap two active windows
+* `C-c d` - duplicate the current line (or region)
+* `C-c r` - rename the currently visited file and buffer
+* `C-c t` - open a terminal emulator (`ansi-term`)
+* `C-c k` - kill all open buffers except the one you're currently in
+* `C-c h` - open Helm (a useful means of navigating your buffers and project files)
+
+#### Projectile
+
+Here's a list of the interactive Emacs Lisp functions, provided by projectile:
+
+* `projectile-find-file` <kbd>C-c p f</kbd>
+* `projectile-grep` <kbd>C-c p g</kbd>
+* `projectile-switch-to-buffer` <kbd>C-c p b</kbd>
+* `projectile-multi-occur` <kbd>C-c p o</kbd>
+* `projectile-replace` <kbd>C-c p r</kbd>
+* `projectile-invalidate-cache` <kbd>C-c p i</kbd>
+* `projectile-regenerate-tags` <kbd>C-c p t</kbd>
+* `projectile-kill-buffers` <kbd>C-c p k</kbd>
+* `projectile-dired` <kbd>C-c p d</kbd>
+* `projectile-recentf` <kbd>C-c p e</kbd>
+* `projectile-ack` <kbd>C-c p a</kbd>
+* `projectile-compile-project` <kbd>C-c p l</kbd>
+* `projectile-test-project` <kbd>C-c p p</kbd>
