 # RyzenAdj
-Adjust power management settings for Ryzen Processors
+Adjust power management settings for Ryzen Processors.
+
+Based on: [FlyGoat/ryzen_nb_smu](https://github.com/flygoat/ryzen_nb_smu)
+
+## Usage
+The command line interface is identical on both Windows and Unix-Like OS.
+
+You should run it with Administrator on Windows or root on Linux.
+
+You can write a shell script or bat to do it automaticly.
+
+```
+$./ryzenadj -h
+
+Usage: ryzenadj [options] [[--] args]
+   or: ryzenadj [options]
+
+ Ryzen Power Management adjust tool.
+
+    -h, --help                show this help message and exit
+
+Options
+    -i, --info                Show information (W.I.P.)
+
+Settings
+    -a, --stapm-limit=<u32>   Sustained power limit (10e-3 W)
+    -b, --fast-limit=<u32>    Fast PPT power limit (10e-3 W)
+    -c, --slow-limit=<u32>    Slow PPT power limit (10e-3 W)
+    -d, --slow-time=<u32>     Slow PPT constant time
+    -e, --stapm-time=<u32>    STAMP constant time
+    -f, --tctl-temp=<u32>     Tctl temperature (℃)
+``` 
+
+### demo
+If I'm going to set all the Power Limit to 45W, and Tctl to 90 ℃,
+then the command line should be:
+```
+./ryzenadj --stapm-limit=45000 --fast-limit=45000 --slow-limit=45000 --tctl-temp=90
+```
+
+## Build
+### Linux
+This project is using cmake, you can search for guides online about how to compile a cmake based program.
+
+Please ensure you have libpci depdency before compile.
+
+### Windows
+It can be built by Visual Studio automaticly. However, as for now, MingW can't be used to compile for some reason.
+
+Required dll is included in ./prebuilt of source tree. Please put the dll library and sys driver in the same folder with ryzenadj.exe.
+
+## TODO
+- Determine the unit of time
+- Add more options
+- Code cleanup (The original program was written in C but now it's C++ in order to call VC++ library)
