+## Csound 7
+The latest beta release installers for MacOS, iOS, and Windows can be downloaded from the relevant [github actions page](https://github.com/csound/csound/actions/workflows/csound_builds.yml). Look for the latest workflow run which has the "develop" label. Clicking on the title brings a page with the download artefacts at the bottom.
 
 ## Building from source
 Building Csound from source or from the git develop branch is not very difficult on Linux, and can also be done on Mac and Windows. How-to descriptions can be found in the BUILD.md file included with the Csound sources, also available online [here](https://github.com/csound/csound/blob/develop/BUILD.md).
