 ## Manual trigger
 
 You can also trigger a build from **Actions → Build and Deploy Lithops Runtime → Run workflow**.

+## Customisation
+
+### Changing the runtime name
+
+The runtime is named `cubed-runtime` by default. To use a different name, edit the `RUNTIME_NAME` env var at the top of `.github/workflows/build-runtime.yml`:
+
+```yaml
+env:
+  RUNTIME_NAME: 'my-runtime-name'
+```
+
+Remember to also update the `runtime` key in your local Lithops config if you change this.
+
+### Using the latest Cubed from GitHub
+
+To use the latest development version of Cubed from the `main` branch instead of the PyPI release, replace the `cubed` line in the `Dockerfile`:
+
+```dockerfile
+RUN pip install \
+        'git+https://github.com/cubed-dev/cubed.git#egg=cubed' \
+        obstore
+```
