+## Setting up Redis With Docker
+
+**NOTE:**
+
+This is just a starting point for using redis within docker. Eventually we'll
+need to set up an image that utilizes nodejs/npm to install our backend
+dependencies, postgresql, and redis to all work within a single container. See
+[this helpful tutorial](https://geshan.com.np/blog/2022/01/redis-docker/).
+
+To run this simple container, simply invoke:
+
+```
+docker-compose -f docker-compose.yml up -d
+```
+
+And if you want to interact with the redis instance via the cli:
+
+// NOTE FOR POSTGRES, EDIT THIS:
+
+```
+docker exec -it <CONTAINER_ID> psql -U <USERNAME>
+```
