+# Micro help text
+
+### Keybindings
+
+These are the default keybindings, along with their actions.
+
+#### Editor bindings
+
+* Ctrl-q:   Quit
+* Ctrl-e:   Execute a command
+* Ctrl-g:   Toggle help text
+* Ctrl-b:   Run a shell command
+
+#### Buffer bindings
+
+* Ctrl-s:   Save
+* Ctrl-o:   Open file
+
+* Ctrl-z:   Undo
+* Ctrl-y:   Redo
+
+* Ctrl-f:   Find
+* Ctrl-n:   Find next
+* Ctrl-p:   Find previous
+
+* Ctrl-a:   Select all
+
+* Ctrl-c:   Copy
+* Ctrl-x:   Cut
+* Ctrl-k:   Cut line
+* Ctrl-v:   Paste
+
+* Ctrl-u:   Half page up
+* Ctrl-d:   Half page down
+* PageUp:   Page up
+* PageDown: Page down
+
+* Home:     Go to beginning of file
+* End:      Go to end of file
+
+* Ctrl-r:   Toggle line numbers
+
+The buffer bindings may be rebound using the `~/.config/micro/bindings.json` file. Each key is bound to an action.
+
+For example, to bind `Ctrl-y` to undo and `Ctrl-z` to redo, you could put the following in the `bindings.json` file.
+
+```json
+{
+    "CtrlY": "Undo",
+    "CtrlZ": "Redo"
+}
+```
+
+### Possible commands
+
+You can execute an editor command by pressing `Ctrl-e` followed by the command.
+Here are the possible commands that you can use.
+
+* `quit`: Quits micro.
+* `save`: Saves the current buffer.
+
+`replace "search" "value"`: This will replace `search` with `value`.
+Note that `search` must be a valid regex.  If one of the arguments
+does not have any spaces in it, you may omit the quotes.
+
+`set option value`: sets the option to value. Please see the next section for a list of options you can set.
+
+`run sh-command`: runs the given shell command in the background. The command's output will be displayed
+in one line when it finishes running.
+
+### Options
+
+Micro stores all of the user configuration in its configuration directory.
+
+Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per the XDG spec,
+if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as the config directory.
+
+Here are the options that you can set:
+
+`colorscheme`: loads the colorscheme stored in $(configDir)/colorschemes/`option`.micro
+	default value: `default`
+	Note that the default colorschemes (default, solarized, and solarized-tc) are not located in configDir,
+	because they are embedded in the micro binary
+
+`tabsize`: sets the tab size to `option`
+	default value: `4`
+
+`syntax`: turns syntax on or off
+	default value: `on`
+
+`tabsToSpaces`: use spaces instead of tabs
+	default value: `off`
+
+`autoindent`: when creating a new line use the same indentation as the previous line
+    default value: `on`
+
+`ruler`: display line numbers
+    default value: `on`
+
+`gofmt`: Run `gofmt` whenever the file is saved (this only applies to `.go` files)
+    default value: `off`
+
+`goimports`: run `goimports` whenever the file is saved (this only applies to `.go` files)
+    default value: `off`
+
+In the future, the `gofmt` and `goimports` will be refactored using a plugin system. However,
+currently they just make it easier to program micro in micro.
