 All of the above can also be run through Docker with `docker-compose`.
 
 ## Running it
+
 ### Backend
+
 - `cp example.env .env` and modify environment variables as required
 - `docker-compose build`
 - `docker-compose up -d phoenix`
   - if you don't specify `phoenix`, it'll also start `gephi` which should only be run as a regular one-off job
+
 ### Frontend
+
 - `cd frontend && yarn install`
 - `yarn start`
 
 ## Commands
+
 ### Backend
 
 After running the backend in Docker:
+
 - `docker-compose run gephi java -Xmx1g -jar build/libs/graphBuilder.jar` lays out the graph
 
 `./gradlew shadowJar` compiles the graph layout program. `java -Xmx1g -jar build/libs/graphBuilder.jar` runs it.
 
 ### Frontend
+
 - `yarn build` to create an optimized build for deployment
