Getting Started

Adding/changing detector geometry

Hint: Use the CI/CD pipelines.

To avoid dealing with setting up all the software, we recommend using the CI/CD to make changes. Any feedback to help this process is appreciated.

Here is how to begin:

1. Look at existing detector constructions and reuse if possible. Note that "compact detector descriptions" -> xml files, and "detector construction" -> cpp file.
2. Modify xml file or detector construction.
3. Create a WIP (or draft) merge request and look at the CI output for debugging. Then go to back to 2 if changes are needed.
4. Remove the WIP/Draft part of the merge request if you would like to see your changes merged into the master.

Compiling (avoid it)

First, see if the use case above is best for you. It most likely is and can save a lot of time for newcomers. To run the simulation locally, we suggest using the singularity image. More details can be found at the links below:
