+## Development
+
+Development of OneChart does not differ from developing a regular Helm chart.
+
+The source for OneChart is under `charts/onechart` where you can locate the `Chart.yaml`, `values.yaml` and the templates.
+
+We write unit tests for our helm charts. Pull requests are only accepted with proper test coverage.
+
+The tests are located under `charts/onechart/test` and use the https://github.com/DataDog/helm-unittest.git Helm plugin to run the tests.
+
+For installation, refer to the CI workflow at `.github/workflows/build.yaml`
+TODO: move it to the Makefile
+
+## Release
+
+`make all` to test and package the Helm chart.
+The chart archives are put under `docs/` together with the Helm repository manifest (index.yaml)
+It is then served with Github Pages on https://chart.onechart.dev
