Contributors management

I learned a lot during my Hacktoberfest participation, especially how I like my contributions to be handled.

Here are some guidelines:

• Write clear issues: the context, where to start in the code, some suggestions on the design
• Give precise review: don't only give an overall feedback of the code, point piece of code and give fix examples
• Be consistent in your requests
• Review the surrounding code when you make a comment (the code may have changed since the last time you had a look at it)
• Try to be regular or considerate when you answer
