+**If you are a musician looking to use Surge, please download the appropriate binary
+[from our website](https://surge-synthesizer.github.io). The Surge developer team makes regular releases for all supported platforms.**

+**If you are a developer looking to compile a stable production version of Surge, please do not
+use the main branch; instead use a release tag (such as `release_1.9.0`) or branch (such as
+`release/1.9.0`). Surge is undergoing substantial 
+development right now, and the `main` branch is currently an 
+incomplete alpha version for our fall 2021 release.**
