+## 🏁 Getting started
+
+### Starting Redis
+
+Before writing any code you'll need a Redis instance with the appropriate Redis modules! The quickest way to get this is with Docker:
+
+```sh
+docker run -p 6379:6379 -p 8001:8001 redis/redis-stack
+```
+
+This launches the [redis-stack](https://redis.io/docs/stack/) an extension of Redis that adds all manner of modern data structures to Redis. You'll also notice that if you open up http://localhost:8001 you'll have access to the redis-insight GUI, a GUI you can use to visualize and work with your data in Redis.
