+ATDB-LDV is the Django backend application for LDV.
+It's main purpose is to hold the state of all the tasks that are in progress for LDV.
+ATDB does not control the flow itself, that is handled by a cloud of micro services.
+Communication is done through the REST API.

 ## CI/CD (semi) automatic 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/ 
+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.
