+#### Behavior
+
+If you are building a client app, and you don't know the processor achitecture.
+
+By creating a folder `x64` and `x86` in the `root` directory, the lib will automatically try to use either `/root/{ARCH}/(ffmpeg|ffprobe).exe`.
+
+If these folders are not defined, it will try to find the binaries in `/root/(ffmpeg|ffprobe.exe)`
