# Use-Cases

The hackathon consists of four use-cases. These use-cases focus on the FHIR `Task` resource. This Resource is the core of Koppeltaal and references other important Resources. At the end of the hackathon, we would like to see the following use-cases working:

1. Assign a `Task` to a `Patient` as a `Practitioner`.
2. Launch a `Task` from a patient portal using [HTI](/technische-howto/launchen.md).
3. Launch a `Task` from a patient portal using [SMART HTI On FHIR](https://github.com/Koppeltaal/Koppeltaal-2.0-Hackathon-Dev-Guide/blob/master/hackathon-use-cases/crud-task/broken-reference/README.md).
