 # Lapis
 A Roblox DataStore abstraction that offers:
-- Caching
-- Session locking
-- Validation (rejects incorrect data)
-- Migrations
-- Retries
-- Throttling
-- Promise based API
-- Immutability
+- **Session Locking** - Documents can only be accessed from one server at a time. This prevents some bugs and duping methods.
+- **Validation** - Ensure your data is correct before saving it.
+- **Migrations** - Update the structure of your data over time.
+- **Retries** - Failed DataStore requests will be retried.
+- **Throttling** - DataStore requests will never exceed their budget and throw an error.
+- **Promise-based API** - Promises are used instead of yielding.
+- **Immutability** - Documents must be updated immutably.
+- **Save Batching** - Pending `Document:save()` and `Document:close()` calls are combined into one DataStore request when possible.
+- **Auto Save** - Documents are automatically saved every 5 minutes.
+- **BindToClose** - All documents are automatically closed when the game shuts down.
 
 This library was inspired by [Quicksave](https://github.com/evaera/Quicksave).

+# Example Usage
+The following code is an example of how you would load and close player data:
+```lua
+local DEFAULT_DATA = { coins = 100 }
+
+local collection = Lapis.createCollection("PlayerData", {
+	defaultData = DEFAULT_DATA,
+	-- You can use t by osyrisrblx to type check your data at runtime.
+	validate = t.strictInterface({ coins = t.integer }),
+})
+local documents = {}
+
+local function onPlayerAdded(player)
+	-- The second argument associates the document with the player's UserId which is useful
+	-- for GDPR compliance.
+	collection
+		:load(`Player{player.UserId}`, { player.UserId })
+		:andThen(function(document)
+			if player.Parent == nil then
+				-- The player might have left before the document finished loading.
+				-- The document needs to be closed because PlayerRemoving won't fire at this point.
+				document:close():catch(warn)
+			else
+				documents[player] = document
+			end
+		end)
+		:catch(function(message)
+			warn(`Player {player.Name}'s data failed to load: {message}`)
+
+			-- Optionally, you can kick the player when their data fails to load:
+			player:Kick("Data failed to load.")
+		end)
+end
+
+local function onPlayerRemoving(player)
+	local document = documents[player]
+
+	-- The document won't be added to the dictionary if PlayerRemoving fires bofore it finishes loading.
+	if document ~= nil then
+		documents[player] = nil
+		document:close():catch(warn)
+	end
+end
+
+Players.PlayerAdded:Connect(onPlayerAdded)
+Players.PlayerRemoving:Connect(onPlayerRemoving)
+
+for _, player in Players:GetPlayers() do
+	onPlayerAdded(player)
+end
+```
+:::info
+You do not need to handle `game:BindToClose` or auto saving. Lapis automatically does both of those.

+# Writing Migrations
+Migrations allow you to update the structure of your data over time. You can add new keys, remove ones you no longer need, or change the way you store something.
+
+Here is an example of a few migrations:
+```lua
+local MIGRATIONS = {
+    -- Migrate from version 1 to 2.
+    function(old)
+        return Dictionary.merge(old, {
+            coins = 0, -- Add a key called coins to the data.
+        })
+    end,
+    -- Migrate from version 2 to 3.
+    function(old)
+        -- We no longer need the playTime key, so we remove it.
+        return Dictionary.removeKey(old, "playTime")
+    end,
+}
+
+local collection = Lapis.createCollection("collection", {
+    migrations = MIGRATIONS,
+    validate = validate,
+    defaultData = DEFAULT_DATA,
+})
+```
