-## Start a local opencpu server

-* run `docker-compose up -d` in the `dev_local` directory of this repository
-  * run `docker-compose down` to stop the server
-* open `http://localhost:80/ocpu/` in your browser to see the opencpu server

+You can test how any changes you make to the fearbase R package affect the deployment of the OpenCPU server by running an
+OpenCPU server locally.
+
+
+### Start the OpenCPU server:
+
+In the `dev_local` directory of this repository run:
+
+```bash
+docker compose up -d --build
+```
+
+### Stop the OpenCPU server
+
+```php
+docker compose down
+```
+
+### Update the OpenCPU server 
+After making changes to the fearbase package. Simply run
+```php
+docker compose up -d --build
+```
+again.
+If you **don't see any changes** it might be the browser caching an old state of the Docker container.
+In that case either delete your browser cache or open the OpenCPU API Explorer in a new **private/icognito session**.
+
+### Testing on the OpenCPU server
+
+Open [http://localhost/ocpu/](http://localhost:80/ocpu/) in your browser to access the OpenCPU API Explorer interface.
+
+In the interface you can run any functions and access included data of the fearbase package by making requests in `../library/fearbase/`. 
+Check the [OpenCPU API docs](https://www.opencpu.org/api.html#api-methods) for information on how to use the OpenCPU API Explorer
