+# OpenTelemetry Collector distributions by jpkrohling
+
+This repository has a personal collection of OpenTelemetry Collector distributions curated by [@jpkrohling](https://github.com/jpkrohling).
+
+At every new version of the Collector, distributions are updated and published.
+
+## Adding a new distribution
+
+To add a new distribution to this repository:
+
+1) create a directory under `distributions` and place the `manifest.yaml` there
+2) add `./github/workflows/ci-<distribution>.yaml` and `./github/workflows/release-<distribution>.yaml` files based on one of the existing distributions
+
+You can test your new distribution with:
+
+```console
+./test/test.sh -d YOUR_DISTRIBUTION
+```
+
+Or, to run everything the CI would run:
+
+```console
+make ci
+```
