Improvements to the home page

• SOURCE TYPE should be required
• "This can be URL or File. (Note: Internet access is required for URL source)". It cannot be a directory. Also a File is a binary and I don't think that's what you mean. I think you mean "This can be URL or a local file/directory path". Note that the dot should be at the end of sentence (ie after parenthesis).
• "URL to the git repository. (e.g. https://github.com/Haxsen/TestRepo.wiki.git)". --> "URL to a git repository (e.g. https://github.com/Haxsen/TestRepo.wiki.git)."
• "URL to the git repository. (e.g. https://github.com/Haxsen/TestRepo.wiki.git)" --> please provide a better example with a real repo.
• "This can be oauth / token / password used for authentication." --> "This can be an oauth, token or password to be used for authentication."
• "The username used for authenticating with password.". Does this mean this field is only used when the previous one is a password? How do you know it's password that was specified?
• "The syntax of the pages will be converted to the Default Page Syntax which is set in Syntaxes (Administration)." --> "Imported pages will be converted to the default page syntax (see the Syntaxes section in the Administration)."
• "Create the pages hierarchically according to their level defined in Sidebar (if exists)." --> "Organize the imported pages hierarchically, following the heading levels defined in the GitHub Pages Sidebar (if it exists)."
• Last but not least, this home page is missing some introduction text to explain what it does.

Thanks
