Note that you can also do it entirely via github without having to use git yourself, assuming this applies to only one file. Just go to the docs of rawproc (<https://nim-lang.org/docs/system.html#rawProc%2CT>) and click on the edit button. You'll get to an edit surface provided by github themselves. Look for `rawProc` and edit the doc comment there.
You can improve the situation even further by also writing a runnableExample (<https://nim-lang.org/docs/system.html#runnableExamples%2Cstring%2Cuntyped>) for the correct useage in there! You'll see whether that works or not in the test-runs nim will start afterwards.
