About GitHub releases

The releases page contains the code and installation files for all development builds of Scratch Addons, as well as the mirror of the store builds.

Cloning the repository

This is the recommended way to install Scratch Addons for development purposes. This assumes you have Git installed.

To download the repository, simply clone https://github.com/ScratchAddons/ScratchAddons.git.

$ git clone https://github.com/ScratchAddons/ScratchAddons.git

To update Scratch Addons, first cd into its folder, and then run the following commands.

$ git fetch
$ git pull

This will update Scratch Addons and get it ready for code editing. Note that you will need to see the finish updating section here if you are using Google Chrome.

Downloading the zipball

If you don’t have Git installed, you can try this method instead. Note that you will need to manually repeat this process every time you want to update Scratch Addons.

  1. Go to the repository and find the download code button.

  5. The extension should now be loaded.

Note: Firefox temporary add-ons are actually temporary. Restarting Firefox will remove them, so if you want to use the development version of Scratch Addons all the time, it is recommended that you use a Chromium-based browser like Google Chrome.
