-## PR Checklist
+## Purpose
 
-- [] I ran `pre-commit run --all-files` locally before creating this PR. (Read [DEVELOPMENT.md](https://github.com/aws/deep-learning-containers/blob/main/DEVELOPMENT.md) for details).
+## Test Plan
+
+## Test Result

+
+<details>
+<summary>Toggle if you are merging into master Branch</summary>
+
+By default, docker image builds and tests are disabled. Two ways to run builds and tests:
+
+1. Using dlc_developer_config.toml
+1. Using this PR description (currently only supported for PyTorch, TensorFlow, vllm, and base images)
+
+<details>
+<summary>How to use the helper utility for updating dlc_developer_config.toml</summary>
+
+Assuming your remote is called `origin` (you can find out more with `git remote -v`)...
+
+- Run default builds and tests for a particular buildspec - also commits and pushes changes to remote; Example:
+
+`python src/prepare_dlc_dev_environment.py -b </path/to/buildspec.yml> -cp origin`
+
+- Enable specific tests for a buildspec or set of buildspecs - also commits and pushes changes to remote; Example:
+
+`python src/prepare_dlc_dev_environment.py -b </path/to/buildspec.yml> -t sanity_tests -cp origin`
 
-## Description
+- Restore TOML file when ready to merge
 
-<!-- Briefly describe the changes in this PR -->
+`python src/prepare_dlc_dev_environment.py -rcp origin`
 
-## Changes Made
+**NOTE: If you are creating a PR for a new framework version, please ensure success of the local, standard, rc, and efa sagemaker tests by updating the dlc_developer_config.toml file:**
+
+- [ ] `sagemaker_remote_tests = true`
+- [ ] `sagemaker_efa_tests = true`
+- [ ] `sagemaker_rc_tests = true`
+- [ ] `sagemaker_local_tests = true`
+

+
+<details>
+<summary>How to use PR description</summary>
+Use the code block below to uncomment commands and run the PR CodeBuild jobs. There are two commands available:
+
+- `# /buildspec <buildspec_path>`
+  - e.g.: `# /buildspec pytorch/training/buildspec.yml`
+  - If this line is commented out, dlc_developer_config.toml will be used.
+- `# /tests <test_list>`
+  - e.g.: `# /tests sanity security ec2`
+  - If this line is commented out, it will run the default set of tests (same as the defaults in dlc_developer_config.toml): `sanity, security, ec2, ecs, eks, sagemaker, sagemaker-local`.
