 # AMD GPU management tools
 
 This repository holds couple tools for AMD graphic cards
 
-* `amdfand` - fan speed daemon
-* `amdvold` - voltage and overclocking tool
-* `amdmond` - monitor daemon
-* `amdguid` - GUI manager
-* `amdgui-helper` - daemon with elevated privileges to scan for `amdfand` daemons, reload them and save config files
+* `amdfand` - fan speed daemon (MUSL)

+## Supported OS
+
+Only Linux is supported.
+
+BSD OS may work if compiled from source, but it wasn't tested.
+I also don't know how to enable all amd gpu features on BSD.
+
+### Officially supported
+
+* Arch Linux
+* Ubuntu 18.04
+* Ubuntu 20.04
+
+### Other
+
+It should be possible to run MUSL programs on any Linux distribution.
+
+GLIBC applications depends on shared glibc libraries and version of this library MUST match.
+
+If you have other version you may download linked version and place it in application directory.
+
+Or you can compile it from source
+
+#### Compile
+
+```bash
+./scripts/build.sh
+```
+
+#### Download missing shared libraries
+
+##### Check linked versions
+
+```bash
+ldd ./amdguid
+```
+

+
+```bash
