			--
			-- The easiest way to use Telescope, is to start by doing something like:
			--  :Telescope help_tags
			--
			-- After running this command, a window will open up and you're able to

			-- Two important keymaps to use while in Telescope are:
			--  - Insert mode: <c-/>
			--  - Normal mode: ?
			--
			-- This opens a window that shows you all of the keymaps for the current
			-- Telescope picker. This is really useful to discover what Telescope can
			-- do as well as how to actually do it!
