 ### WORK IN PROGRESS
 This is still early WIP. Many features are not implemented yet and quite a few are still unstable. Right now Clapper can only play single file. So if you want to test it, start it from terminal like this:
 ```shell
-clapper video.mp4
+com.github.rafostar.Clapper "video.mp4"
 ```

 ## Requirements
 Clapper uses `GStreamer` bindings from `GI` repository, so if your repo ships them as separate package, they must be installed first.

 ## Installation
 Run in terminal:
-```sh
-sudo ./install.sh
+```shell

+sudo meson install -C builddir
 ```
-I know that this should be done using some sort of build system (like `meson`), but the player is still far from finished and a basic install script should be sufficient for the time being, if anyone wishes to test it.
 
 ## Hardware acceleration
 Using hardware acceleration is highly recommended. As stated in `GStreamer` wiki:
