 ---@brief [[
---- A collection of builtin pickers for telescope.
----
---- Meant for both example and for easy startup.
+--- Telescope Builtins is a collection of community maintained pickers to support common workflows. It can be used as
+--- reference when writing PRs, Telescope extensions, your own custom pickers, or just as a discovery tool for all of
+--- the amazing pickers already shipped with Telescope!
 ---
 --- Any of these functions can just be called directly by doing:
 ---
---- :lua require('telescope.builtin').$NAME()
+--- :lua require('telescope.builtin').$NAME_OF_PICKER()
+---
+--- To use any of Telescope's default options or any picker-specific options, call your desired picker by passing a lua
+--- table to the picker with all of the options you want to use. Here's an example with the live_grep picker:
 ---
---- This will use the default configuration options.
----   Other configuration options are still in flux at the moment
+--- <pre>
+--- :lua require('telescope.builtin').live_grep({
+---    prompt_title = 'find string in open buffers...',
+---    grep_open_files = true
+---  })
+--- </pre>
+---
+--- This will use the default configuration options. Other configuration options are still in flux at the moment
