 These diagrams are the core of the ATDB documentation.
 Currently they are still mostly the original ATDB diagrams. They will be adapted and kept in sync once the ATDB-LDV structure solifies a bit more.

+## Manual deploy in Docker
 For the `master' branch there is a CI/CD pipeline in place which builds and deploys the backend at https://sdc.astron.nl:5554/atdb/ 
 The deploy step requires pushing the 'play' button in the gitlab pipelines section. 
 This is done to not have a mandatory deploy for every minor commmit.
