+### Checkin
+
+- Do checkin source (src)
+- Do checkin a single index.js file after running `ncc`
+- Do not checking node_modules
+
+### NCC
+
+In order to avoid uploading `node_modules` to the repository, we use [zeit/ncc](https://github.com/zeit/ncc) to create multiple `index.js` files that gets saved under `dist/`.
+There are two main files that get created
+- `dist/setup/index.js`
+   - Core `setup-java` logic that downloads and installs an appropriate version of Java 
+   - Handling creating a `settings.xml` file to make it easier to publish packages
+- `dist/cleanup/index/js`
+   -  Extra cleanup script that is used to remove GPG keys (needed for certain self-hosted runner scenarios)
+
+If you're developing locally, after doing `npm install`, you can use the following commands
+```yaml
+npm run build # runs tsc along with ncc
+npm run format # runs prettier --write
+npm run format-check # runs prettier --check
+npm run test # runs jest
+npm run release # add all the necessary ncc files under dist/* to the git staging area
+```
+
+Any files generated using `tsc` will be added to `lib/*`, however those files also are not uploaded to the repository and are excluded using `.gitignore`.
+
+### Testing
+
+Tests are included under `_tests_/*` and can be run using `npm run-script test`.
+
+We ask that you include a link to a successful run that utilizes the changes you are working on. For example, if your changes are in the branch `newAwesomeFeature`, then show an example run that uses `setup-python@newAwesomeFeature` or `my-fork@newAwesomeFeature`. This will help speed up testing and help us confirm that there are no breaking changes or bugs.

+
+If `gpg-private-key` input is provided, the private key will be written to a file in the runner's temp directory, the private key file will be imported into the GPG keychain, and then the file will be promptly removed before proceeding with the rest of the setup process. A cleanup step will remove the imported private key from the GPG keychain after the job completes regardless of the job status. This ensures that the private key is no longer accessible on self-hosted runners and cannot "leak" between jobs (hosted runners are always clean instances).

-- Do not checking node_modules
-
-### NCC
-
-In order to avoid uploading `node_modules` to the repository, we use [zeit/ncc](https://github.com/zeit/ncc) to create a single `index.js` file that gets saved in `dist/`.
-
-If you're developing locally you can run
-```
-npm install
-tsc
-ncc build
-```
-You can also do
-```
-npm run-script build # runs tsc
-npm run-script format # runs prettier --write
-npm run-script format-check # runs prettier --check
-npm run-script test # runs jest
-npm run-script release # runs ncc build
-```
-
-Any files generated using `tsc` will be added to `lib/*`, however those files also are not uploaded to the repository and are excluded using `.gitignore`.
-
-### Testing
-
-Tests are included under `_tests_/*` and can be run using `npm run-script test`.
-
-We ask that you include a link to a successful run that utilizes the changes you are working on. For example, if your changes are in the branch `newAwesomeFeature`, then show an example run that uses `setup-python@newAwesomeFeature` or `my-fork@newAwesomeFeature`. This will help speed up testing and help us confirm that there are no breaking changes or bugs.
