+## Build & Release
+To build a new copy of this workflow for development:
+
+<br />
+
+### Install
+
+```shell
+npm install
+```
+
+<br />
+
+### New Github Release
+To push a new release, first run eslint locally to check for issues
+```shell
+npm run lint
+```
+
+<br />
 
+Then open the `package.json` and bump the version. Then push the updated `package.json` file to the repo:
+```json
+{
+    "name": "delete-deployment-environment",
+    "version": "3.0.1",
+}
+```
+
+<br />
+
+Run the workflow `release-publish.yml` from https://github.com/Aetherinox/delete-deploy-env-action/actions.
+
+<br />
+
+Once you run the publish workflow, a second workflow will be ran: `.github\workflows\release-publish-tag-latest.yml`. This will create an additional new release with the tag `latest` so that you can use the workflow in your .yml file under the `latest` tag:
+
+```yml
+jobs:
+    cleanup:
+        runs-on: ubuntu-latest
+        permissions: write-all
+  
+        steps:
