#!/usr/bin/env bash
# Description: This is a script to make the release process easier
# Run it with `yarn release:prep` and it will do the following:
# 1. Check that you have gh installed and that you're signed in
# 2. Update the version of code-server (package.json, docs, etc.)
# 3. Update the code coverage badge in the README
# 4. Open a draft PR using the release_template.md and view in browser
# If you want to perform a dry run of this script run DRY_RUN=1 yarn release:prep
