The easiest way to install it is directly from WordPress.org. Visit the official plugin page.

Or download from GitHub

  1. Go to the Releases page and open the latest release.
  2. Under Assets, click Source code (zip) to download.
  3. Inside the extracted folder, you’ll find another folder with the same name — that’s the plugin. Its name has the version tag appended (e.g. simple-course-creator-v1.2.3). Remove the version suffix so the folder is named just simple-course-creator.
  4. Re-zip that folder. That’s your installable plugin file.
  5. In your WordPress admin, go to Plugins > Add New Plugin > Upload Plugin, select your zip, and install.

GitHub will always have the latest active development in the branches. However, a tagged release should match the WordPress.org version exactly.
