Requesting Help Installing a Build - No experience

NullForce made this wonderful scrolling app for OBS, but I’m confused I never used Dot net before. I tried to install dot net and copypaste the command and it keeps coming up with
C:\Users\User>dotnet run --project src/Nullforce.StreamTools.ImageScrollerdotnet run --project src/Nullforce.StreamTools.ImageScroller
MSBUILD : error MSB1009: Project file does not exist.
Switch: src/Nullforce.StreamTools.ImageScrollerdotnet

The build failed. Fix the build errors and run again. "

Not sure what to do since I havent been able to get past that step in the Read Me… I have 0 exp with any sort of code and such. I just get very confused very fast if its not an install .exe (I’m a bit dull I know lol)

So if someone could explain in simple terms or an simple video it would be heavily appericated
