+## Prerequisites
+
+1. NodeJS and preferably Node Version Manager to be able to swap between supported versions
+2. Yarn
+
+## Running locally
+
+To run `rotten-deps` with a predefined configuration file you can:
+1. Use command `yarn install` to install dependencies.
+2. Use command `yarn run start`  which will build and then run `rotten-deps` using config [sample-config.json](./sample-config.json).
+
+If you would like to have more control over the arguments and configuration used:
+1. Use command `yarn install` to install dependencies
+2. Use command `yarn run build` to compile and build the application
+3. Use command `node ./bin/rotten-deps [args]` to run it locally. 
+
+## Testing
+
+Use `yarn test` to run CLI and API tests
+
+## Submitting changes for review
+
+When you feel like your changes are at a point where you'd like feedback, or if you feel they are ready for show time, create a pull request.
+This will run the tests and other CI checks as well as signaling to the maintainers it is ready to go.
+
+Once you've created a pull request It would be nice if you could update the [CHANGELOG.md](./CHANGELOG.md) and add a bullet about your change
+to the unreleased section with a link to your pull request. See the 'Keeping a changelog' section for more details.

+## Keeping a changelog
+
+This project will use https://keepachangelog.com/en/1.0.0/ as the format for it's change log
+
+## Release
+
+We're investigating automating this release and publish process but for now here are the steps to generating a release.
+
+1. Checkout branch `main` and make sure it is up to date
+2. Run command `yarn install` then `yarn run build` to prep the application for deployment
+3. Update [CHANGELOG.md](./CHANGELOG.md) and change the [UNRELEASED] section to reflect your next semver version (v1.0.0, v1.2.3, v2.3.4-beta001).
+4. Stage the CHANGELOG.md changes in git but using command `git add CHANGELOG.md`
+5. Double check that your working directory is clean other than the CHANGELOG.md change using `git status` or `git diff`. The following
+command is dangerous and will add any dirty changes.
+6. Use the command `npm version --force <semver>`
+  * `--force` is what will include the CHANGELOG.md changes in this release commit and tag
+7. Use the command `npm publish --access public` to publish
+
