+## Setting up Redis
+
+In order to utilize server side caching, a Redis instance must be available and running. Redis installation and quick-start documentation can be found [here](https://redis.io/docs/getting-started/). Make sure to keep a redis instance running whenever the application is utilizing server side caching to avoid running into issues.
+
+To connect Obsidian to Redis, create a .env file in the root directory of the application with the following information:
+
+```javascript
+REDIS_HOST= //string of redis host name, typically defaulted to '127.0.0.1' by Redis
+```
+Be sure to also specify the Redis TCP port by passing in the port number as an argument into Obsidian Router (see Selecting options for the Router above).
