Check and fix website text

I have a small website written in English but I am not a native English speaker. I need someone to check the text and fix the grammar errors that I probably made. I would also want the worker to re-write or partially write the explanations that may not sound well to native English speakers. The website is the following: [login to view URL] Most of the contents are under the documentation tab. ## Deliverables I will send the worker the necessary files (most of them HTML) to edit the contents directly on this files. It is not needed to understand HTML as text can be easily edited in this files. Thechnical skills (or at least understand the context of the website) are highly appreciated although not a must.
