+
+## Command Definitions
+
+Commands that are directly supported by **RediStack** will use the same spelling and naming as found in Redis,
+and are defined as static functions.
+
+For the full list of Redis commands, reference the [Redis Command documentation](https://redis.io/commands).
+
+Some commands are available directly as extensions on ``RedisClient``.
+
+## Custom Commands
+
+If a command is not directly supported by **RediStack**, you can write your own extension on ``RedisCommand`` and use
+the various initializers.
+
+While the `ResultType` of the command is a concrete Swift type, such as an enum, it needs to first be parsed from
+the raw ``RESPValue`` Redis response, which is done with the `mapValueToResult` closure of ``init(keyword:arguments:mapValueToResult:)``.
+
+For types conforming to ``RESPValueConvertible``, this done automatically with the `init(keyword:arguments)` initializer.
