1. Go to VS Marketplace.
2. Click on the "Install" button.
3. Then select a theme. The GitHub themes try to match the themes available in github.com's settings:
   • GitHub Light Default
   • GitHub Dark Default
   • GitHub Dark Dimmed
   • GitHub Dark High Contrast ✨ new ✨

Additionally, there are also two older themes. Note: They won't get updated anymore and are kept for legacy reasons:

• GitHub Light (legacy)
• GitHub Dark (legacy)

To quickly test something, you can also override this (or any other) theme in your personal config file. Please follow the guide in the color theme documentation.

1. Clone and open this repo in VS Code
2. Run npm install to install the Primer CSS color reference and run npm start to run the converter.
3. Press F5 to open a new window with your extension loaded
4. Open Code > Preferences > Color Theme [⌘k ⌘t] and pick the "GitHub Light" or "GitHub Dark" theme
5. Make changes to the /src/theme.js file.
   • UI: For all changes to the "outer UI", like (status bar, file navigation etc.), take a look at the Theme Color reference.
   • Syntax: For changes to the "code highlighting", examine the syntax scopes by invoking the Developer: Inspect Editor Tokens and Scopes command from the Command Palette (Ctrl+Shift+P or Cmd+Shift+P on Mac) in the Extension Development Host window.
6. Commit your changes and open a PR.

Note:

• If possible use colors from Primer's color system.
• Changes to the theme files are automatically applied to the Extension Development Host window, so no reloading should be necessary.

Note: Publishing a new version of this theme is only meant for maintainers.

Prerequisite: Please follow this guide to install and login to vsce. Ask an existing maintainer how to get the "Personal Access Token".

1. Merge any PR that is ready to be published into master.
2. Run npm run build to generate the themes with the new changes.
3. Update CHANGELOG.md + commit the changes.
4. Run vsce publish [version]. Follow the SemVer convention and replace [version] with one of the following options:
   • patch for bug fixes
   • minor for improvements
   • major for breaking or bigger changes
5. Push the commits and make a new release.
