Editing the Quick Start Docs

[braim23]

Fixed some bits and small details. added articles such as "a", "an" and "the" when needed and deleting them when they weren't needed.

For example: There is one source code that we'll talk about and it is specific. So we'll say:
"You can find the* source code of the completed application".

Also, when we say:

"Go to the blabla.cs file"

'file' is a noun, and since we used a noun, we are supposed to add an article 'the'. Same goes if we say 'class', 'project', etc. instead of 'file'.

But when we say:
"Go to blabla.cs"

We didn't use a noun here, so we don't need to add 'the' at all, and this explains why I removed some "the"s.
