I would like to suggest changes to the Help files. I have very limited experience using Github. Might someone take the time to walk me through the community's preferred process and I promise to reciprocate with many suggestions for changes to Help files.
for small simple changes you can edit the schelp file directly on github and when saving it will fork and create a branch for you, allow you to send a pull request.
but if you mess with tags or formatting in the help file then its easy to break the file. so you would need to edit the original schelp source files and make sure that they compile and show up in the help browser. then make a pull request
