 ## Extending the IDP builder
 In the future we hope to allow for a pluggable interface to allow for extending the IDP builder with additional argo apps. For now you simply need to add additional apps in the [Embedded Apps](https://github.com/cnoe-io/idpbuilder/blob/4b0f8ecdd7266083373da51d5add1bca73e05a33/pkg/apps/resources.go#L20-L32) and also add the resources they will deploy in the `srv` folder: [pkg/apps/srv](https://github.com/cnoe-io/idpbuilder/blob/4b0f8ecdd7266083373da51d5add1bca73e05a33/pkg/apps/srv/)

+## Testing
+
+This project includes different test cases (unit, integration) which can be executed using the command `make test` or directly within your favorite IDE.
+
+**Remark**: As some tests require to access docker, then this is a prerequisite to launch it first !
