Usage

This theme requires that you use a user styles extension for your browser, such as Stylus (available for Firefox, Chrome, and Opera).

Desktop App

No official support. Workarounds exist.

• dark-slack cli
• slack-theme-cli

🛑 READ FIRST: Most workarounds will request the compiled CSS file from this repository. You are strongly discouraged from using a remote CSS file. It's recommended that you create your own copy. An XSS attack could put your Slack client at risk.
