Hi Muhammad,

From my experience and the others around, just use it for a document/paper/thesis... Take a template and write your document. When you have a problem, you will find plenty of solution on the web.

The answer may seem too simple, but it is actually how a latex user I know learnt how to use it....

Here are some links to get you started:

Prepare a paper using latex. Just do it.

Thank you Jonathan, Artur and Deyuan
