+Scripting
+===
+
+Basic [Lua scripting](http://redis.io/commands/EVAL) is supported by the `IServer.ScriptLoad(Async)`, `IServer.ScriptExists(Async)`, `IServer.ScriptExists(Async)`, `IDatabase.ScriptEvaluate`, and `IDatabaseAsync.ScriptEvaluateAsync` methods.
+These methods expose the basic commands neccessary to submit and execute Lua scripts to redis.
+
+More sophisticated scripting is available through the `LuaScript` class.  The `LuaScript` class makes it simpler to prepare and submit parameters along with a script, as well as allowing you to use 
+cleaner variables names.
+
+An example use of the `LuaScript`:
+
+```
+	const string Script = "redis.call('set', @key, @value)";
+
+	using (ConnectionMultiplexer conn = /* init code */)
+	{
+		var db = conn.GetDatabase(0);
+
+		var prepared = LuaScript.Prepare(Script);
+		db.ScriptEvaluate(prepared, new { key = (RedisKey)"mykey", value = 123 });
+	}
+```
+
+The `LuaScript` class rewrites variables in scripts of the form `@myVar` into the appropriate `ARGV[someIndex]` required by redis.  If the 
+parameter passed is of type `RedisKey` it will be sent as part of the `KEYS` collection automatically.
+
+Any object that exposes field or property members with the same name as @-prefixed variables in the Lua script can be used as a paramter hash to
+`Evaluate` calls.  Supported member types are the following:
+
+ - int(?)
+ - long(?)
+ - double(?)
+ - string
+ - byte[]
+ - bool(?)
+ - RedisKey
+ - RedisValue
+
+
+To avoid retransmitting the Lua script to redis each time it is evaluated, `LuaScript` objects can be converted into `LoadedLuaScript`s via `LuaScript.Load(IServer)`.
+`LoadedLuaScripts` are evaluated with the [`EVALSHA`](http://redis.io/commands/evalsha), and referred to by hash.
+
+An example use of `LoadedLuaScript`:
+
+```
+	const string Script = "redis.call('set', @key, @value)";
+
+	using (ConnectionMultiplexer conn = /* init code */)
+	{
+		var db = conn.GetDatabase(0);
+		var server = conn.GetServer(/* appropriate parameters*/);
+
+		var prepared = LuaScript.Prepare(Script);
+		var loaded = prepared.Load(server);
+		loaded.Evaluate(db, new { key = (RedisKey)"mykey", value = 123 });
+	}
+```
+
+All methods on both `LuaScript` and `LoadedLuaScript` have Async alternatives, and expose the actual script submitted to redis as the `ExecutableScript` property.
