 # citron-nightly
 
-Automatically generated nightly releases for Citron
+Steamdeck optimized nightly builds of the [Citron] emulator.
+
+## How are these optimized?
+
+Compilation is performed with LTO and O2 compilation as well as with all of the
+feature sets supported by the steamdeck processor. So, it's optimized :smile:
+
+## How do I download these? 
+
+Releases are published nightly on our [releases](https://git.rgst.io/jaredallard/citron-nightly/releases) page.
+
+These releases are created automatically through [actions](https://git.rgst.io/jaredallard/citron-nightly/actions). Although
+they run every day, a release will only be published once for a given commit.
