+## How to get a build
+
+Click on the Actions tab above, this will take you to a list of builds.
+
+Choose the latest build from the `x64` branch, as builds older than ninety days have their artifacts automatically removed.
+
+> Make sure it has the "SteamWorks.ext Build" subtext!
+
+Pick the artifact that suits what your server is running on.
+
+Click on the download icon _(down arrow with tray)_ to download the artifact,
+if the icon is not visible, you have to sign in to GitHub in order for it to let you download them.
+
+## Differences in Linux builds
+
+The `ubuntu-22.04` and `ubuntu-24.04` builds differ in the environment they
+were built in. Meaning that the version of `glibc` which they are using and expect as a minimum in order to run differs.
+
+For reference:
+
+`ubuntu-22.04` uses glibc 2.35.
+
+`ubuntu-24.04` uses glibc 2.39.
