Changes to the documentation

[Tanaya9299]

A more detailed documentation should be uploaded on the website with all the 32 Fiducials and their details
Also in the documentation
The sequence be mentioned as

1. creating the new markup fiducial
   Labelling all the 32 fiducials
2. creating ACPC transform and midline
   Copying the required fiducials
3. registration (here it will be nice to mention to toggle the eye icon as most of the times after clicking apply only the fiducials are visible and for like the first couple of times I thought I missed something or did it incorrectly and had to start again)
4. Transform
   Also it should contain a FAQ section for the most common areas of mistakes and their solutions as I mentioned for registration.
   Personally I think it will reduce most of the confusion and simplify the learning process.

Thanks for your comments, @Tanaya9299. If you have specific ideas on how to go about this, consider opening a PR. Over the coming months, we hope to work with a technical writer as part of the Google Summer of Docs program to solve some of these ambiguities.
