+## Bazel Central Repository -- Unfinished documentation
+
+Documentation: 
+https://github.com/bazelbuild/bazel-central-registry/blob/main/docs/README.md
+
+
+PH-Tree build target:
+```
+bazel build //:phtree
+```
+
+#### Start
+
+Checkout personal fork of bazel-central-registry.
+Create branch `phtree-cpp@1.6.2`.
+
+#### After modifying any file
+
+Recreate hashes for `source.json`
+```shell
+bazel run -- //tools:update_integrity phtree-cpp
+```
+ This also accepts `--version` but defaults to latest version.
+
+#### Validate 
+
+```shell
+bazel run -- //tools:bcr_validation --check=phtree-cpp@1.6.2
+```
+
+#### Test locally
+
+```bash
+bazel run //tools:setup_presubmit_repos -- --module phtree-cpp@1.6.2
+```
+
+There is also a GitHub action for release automation:
+https://github.com/bazel-contrib/publish-to-bcr
+
+
+#### Test with Test repos
+
+Check out `test-phtree-cpp-bazel` and run:
+
+```shell
+bazel shutdown && bazel build --enable_bzlmod --registry="file:///home/.../bazel-central-registry" --lockfile_mode=off @phtree-cpp//:phtree-cpp
+--> Target might be incorrect
+```
