Improve Login Switch project page

Below are some ideas for some areas of improvement around the documentation of the module:

Project page, could be a little bit more detailed:

1 - Project page description:
We could certainly add more information about the module's configuration.

• Introduction: one liner to let users know what this module does (200 chars max).
• Features: what the module can do.
• Implementation: how the module does what it does.
• Troubleshooting (Known Theme issues): For example, potentially conflicting modules, related with the Core User login pages or the login/authentication process.
• Review recommendations at: Project page template, Module documentation guidelines, Tips for a great project page, Best practices for creating and maintaining projects and README Template.
• Similar projects: other modules that do more or less the same things as this one.
• Many other sections: see the sections suggested by the Project page template, README Template and Tips for a great project page documents, for example, Troubleshooting, Known issues, Future developments, etc...

2 - Screenshots:
Consider adding screenshots that could demonstrate module's features:

• Backend settings form with all options expanded and example values in the fields.
• Front end display of the feature with the different routes overrides.

 
Examples of documented project pages:

• Block Attributes
• Image Link Formatter

Feel free to let me know if you would have any comments, feedback, questions, issues, objections, suggestions, additions or concerns on this task, I would surely be glad to provide more information or explain in more details.

Thanks in advance to everyone for your testing, reviews, feedback and comments on this issue.
Cheers!
