 ## Running
 
-To run `shortenit`, first we need to have a running database. Shortenit uses [CouchDB](https://couchdb.apache.org/) as a database. CouchDB can run as a docker container.
-
-```text
-$ docker run -p 5984:5984 -e COUCHDB_USER=root -e COUCHDB_PASSWORD=root -d couchdb 
-```
-
-At this point, visit the local instance link [http://localhost:5984](http://localhost:5984/) and create the user credentials configured in [config/config.yaml](config/config.yaml).
-
-Once the database is up and running and the credentials have been created, shortenit can be ran.
+To run `shortenit`, edit the configuration file found in [config/config.yaml](config/config.yaml) then run the following commands.
 
 ```text
 $ pip install -e .
