+
+[::b]SYNOPSIS
+	[::b]Normal Mode: Navigate around the containers with hjkl.
+	Perform some usual commands inside text box input, as pasting, moving cursor or such.
+	Press ESC anywhere to return to normal mode.
+
+	[::b]Insert Mode: Type inside box input, perform actions inside chatview.
+	Insert without any key restriction inside the text box using insert mode.
+	Inside chat view, perform useful commands such as editing message "i" or replying to user "a"
+
+	[::b]Visual Mode: Move around everywhere with vim keys.
+	This mode allows to use hjkl pretty much anywhere inside the app. Due to some restrictions, this is
+	the only mode that officially supports using hjkl anywhere.
+	Also allows using same commands as insert mode inside chat view, or selecting text inside text input.
+
+
+[::b]DESCRIPTION
+	This is a minor mode for vim. See all the shorcuts with Ctrl K, and edit them inside shortcuts/shortcuts.go`
