+
+|Command|Description|

+|`./run.sh api`|Runs the API locally for development.|
+|`./run.sh app`|Runs the app locally for development.|
+|`./run.sh clean`|Cleans all projects of build artefacts and other temporary files.|
+|`./run.sh build`|Builds all projects to produce artefacts for final usage.|
