 -- A declarative API to connect signals for the AwesomeWM.
 -- It completes the native `gears.signal` module to make signal connection
 -- easier to manage.
+--
+-- Usage example
+-- ---
+--
+-- Tis module allows to create Slot objects. These object can connect to any
+-- signals from Awesome WM's `gears.object`s and module level signals.
+--
+-- In the following example, we create a slot that connects to the `client`
+-- global `"request::default_keybindings"` signal to attach keybindings to
+-- clients.
+--
+-- The `slot.slots.client.append_keybindings` function is part of this module
+-- and is defined as a function iterating over the `keybindings` parameter to
+-- register all defined keybindings with the `awful.keyboard.append_client_keybindings`
+-- function.
+--
+--    local client_keybinding = slot {
+--      id = "CLIENT_KEY_BINDINGS",
+--      connect = true,
+--      target = capi.client,
+--      signal = "request::default_keybindings",
+--      slot = slot.slots.client.append_keybindings,
+--      slot_params = {
+--        keybindings = {
+--          awful.key({ "Mod4" }, "f",
+--            function(client)
+--             client.fullscreen = not client.fullscreen
+--             client:raise()
+--            end,
+--            { description = "toggle fullscreen", group = "client" }),
+--          },
+--          -- ...
+--        },
