Update on user guide

[PanSwift]

Thank you for the comprehensive guide, I found it quite useful by including the following tweaks.

1. for the variable , delete "25000", as it may not be the case for everyone.
   your may find your course id at
   https:///api/v1/courses?access_token=&per_page=10000

2. update canvas api to "https:///api/v1/" as some school may prefer to host their canvas locally, not using the ".instructure.com" domain.

3. I have also change the course id to exactly the "name" retreived from the "/api/v1/course" object in the course API.

I have tried CanvasSync, canvasFileSync so far, and this is the only one I have successfully downloaded a file from canvas.

Thank you very much!

I don't know why it behaves like so!
