+# BCR Publisher
+
+This document explains how to use the `publish-to-bcr.sh` script to publish `googleapis` to the Bazel Central Registry (BCR).
+
+## Usage
+
+The `publish-to-bcr.sh` script is used to automate the process of creating a new version of the `googleapis` module in the BCR.
+
+### Arguments
+
+The script accepts the following arguments:
+
+*   `-r`, `--ref`: **(Required)** The git ref (commit SHA, tag, or branch) of `googleapis` to be published.
+*   `-t`, `--templates_ref`: The git ref to use for the templates. Defaults to the value of `--ref`.
+*   `-o`, `--org`: The GitHub organization. Defaults to `googleapis`.
+*   `-p`, `--protobuf_version`: The version of protobuf to use. Defaults to `21.7`.
+*   `-b`, `--bcr_organization`: The GitHub organization for the Bazel Central Registry. Defaults to `bazelbuild`.
+*   `-f`, `--bcr_folder`: The local path to a fork of the `bazel-central-registry` repository. If not provided, the script will clone it from `https://github.com/{bcr_organization}/bazel-central-registry`.
+
+### Example
+
+```bash
+./publish-to-bcr.sh --ref <your-commit-sha>
+```
+
+### After running the script
+
+After the script is executed, it will perform the following actions:
+
+1.  A new branch will be created in your local fork of `bazel-central-registry`.
+2.  The script will prompt you to create a Pull Request. If you agree, a new PR will be created in the `bazelbuild/bazel-central-registry` repository.
+3.  The script will automatically add a comment to the PR with the content: `@bazel-io skip_check unstable_url`. This is necessary to bypass the URL stability check.
+
+Once the Pull Request has been created and all Continuous Integration (CI) checks are passing, a maintainer of the Bazel Central Registry will review and merge it.
+
+#### Note on re-running the script
+
+During development, you may need to run the script several times.
+Between each call, it's strongly recommended to reset your local fork of bazel-central-registry.
+For this, you can run the following command:
+
+```bash
+pushd "${fork_location}"
+git reset --hard
+git checkout main
+git clean -d -f
+popd
+```
+
+## Testing
+
+To run the unit tests for the script, use the following command:
+
+```bash
+./publish-to-bcr_test.sh
+```
