* Vocabulary corrections on the first two paragraphs
Added some portuguese grammar elements; the document is written in brazilian portuguese (a derivate from portuguese itself), however it may benefit the most if converted into regular portuguese.
* small format and word changes for the PR
* fixed typo in first line
There was becuase instead of because!
* Removed second typo.
I've removed the second type as requested, thank you I've totally not seen this at first!
There's an error in the HTML Anchor link. Link's description has no Anchor reference.
The other corrections aim to create a more "natural language" translation.
