+### Installation
+
+Go to [the latest release](https://github.com/lstrojny/prometheus-weathermen/releases/latest) and download the
+appropriate binary for your platform.
+
+The following platforms are supported:
+
+| Platform     | Use case                          |
+| ------------ | --------------------------------- |
+| arm-linux    | 32 bit armhf, e.g. Raspberry Pi   |
+| arm64-linux  | 64 bit arm, Raspberry Pi 4        |
+| x86_64-linux | 64 bit X86 architecture for Linux |
+| intel-mac    | Intel based Macs                  |
+| arm-mac      | M1/M2 based ARM Macs              |
+
+Please open an issue if your favorite platform is missing. It’s probably not terribly much work to get it going.
+
+There are `dbg` (debug) variants of the binaries. These are unstripped debug builds. If you don’t know what that is, you
+don’t want it.
+
+For the Linux builds, `static` variants based on [musl libc](https://www.musl-libc.org/) are available. These are
+statically linked binaries that can be used to run `prometheus-weathermen` in a container with minimal fuzz. The non-static
+counterparts for Linux are build against glibc.
