The devops services used to support the devGaido app include:
| DevOps Service | Directory | Purpose |
|---|---|---|
| App runtime | runtime | Application runtime configuration |
| DevOps automation | runtime | Automation scripts and configuration |
| Documentation | docs | App and DevOps documentation |
Issues should be reported on the main GitHub repo for the devGaido App sto consolidate all issues in one location. Similarly, wiki entries should be created on the main repo for the same reason.
