+### 1.4 [Optional] Create a PR to [AOC Repo](https://github.com/aws-observability/aws-otel-collector) and record the version number
+
+This is optional item, only do it if your goal is to add a component or fix a bug into the AOC Repo. Everytime when you create a PR to AOC repo, there will be a workflow to be running in this PR to do regression test and also, build testing artifacts[rpm, image, etc] for your code. Every PR will have a separate version number which you will be able to use it in the testing framework to verify whether your new code can pass your new testing suite.
+
+1. create a branch in [AOC Repo](https://github.com/aws-observability/aws-otel-collector). [please don't fork at this moment, just create a branch directly in the AOC Repo]. [todo, after the repo becomes public, you can use fork instead of creating branch]
+
+2. create a PR to merge the new branch to the `main` branch.
+
+3. Waiting for the workflow checking in the PR to be finished.
+
+4. find out the version number, click into the workflow page, click `e2etest-preparation` step, and click `Versioning for testing`, record the version number. Ex(v0.1.12-299946851).
+
+5. provide your testing aws account id to Ying(wangmyin@), so that he will give permission to your aws account to fetch the testing image from a private ECR. [todo, once we migrate to dockerhub, you don't need this step]
