+# Contributing to VSCode CSSVar extension
+[Draft]
+
+Thanks for your support and taking time to contribute! 🎉👍
+
+## Prerequisites
+
+## Release/Deployments
+
+Currently Deployments are managed manually by @phoenisx. I might make this more public in future, for now
+keeping it manual was the most easiest way for me.
+
+### Releasing a new version
+
+It's a two step process (and has a lot of room for improvement)
+
+I maintain two custom scripts:
+
+**`src/scripts/create-changelog.js`**
+This is required to automate creating changelog once all the changes are merged to `main` and are about to be released.
+This script assumes that we already have previous release version tag present in git history where the command is run.
+
+We can run the following:
+```sh
+node src/scripts/create-changelog.js v2.6.4..HEAD | pbcopy
+```
+to generate changelog between previous release and latest commit.
+If the generated content is copied to clipboard we can use that content to modify our `CHANGELOG.md`.
+
+Once we are satisfied with the updated CHANGELOG, we can commit the changes and create a new release on Github
+
+**`src/scripts/publish.js`**
+
+Publishing our release to VSCode/OVSX extension marketplaces.
+We need the private tokens for both these marketplaces for this command to work.
+Running this script will than auto publish our changes to both these marketplaces.
