+## Installation (Binary Builds)

+Development builds are now available that should work stand-alone without Anaconda. Click on the newest build with a green checkmark [here](https://github.com/jmwright/CQ-editor/actions?query=workflow%3Abuild), wait for the _Artifacts_ section at the bottom of the page to load, and then click on the appropriate download for your operating system. Extract the archive file and run the shell (*nix) or batch (Windows) script in the root CQ-editor directory. The CQ-editor window should launch.

+A stable version of these builds will be provided in the future, but are not available currently.
