This is a quick & dirty experiment to show sketchtool running on GitHub Actions.

Whenever a .sketch document is pushed or merged to master, a GitHub Action will run and:

• Download & install the latest Sketch version
• Run sketchtool export to extract all the exportable assets in your document
• Archive all those assets in an assets.zip file
• Create a new release in the repo, and attach assets.zip to it

All the paths are hardcoded, but the code is trivial enough to modify for your particular needs. See .github/workflows/sketchtool.yml for more details.

Huge props to @mathieudutour for his help with the release process.
