Playing with words and clarifying the "mission" of Exercism

Assuming I __do__ understand the intent, I think these changes make it a bit clearer and simpler to read.
Admittedly, there is more that can be done.

If you like my writing style just relate to me the point(s) you want to get across and I will work on this a bit more.

I am very proud to contribute to this wonderful project.
