FIX: README update with error fixes

[mishmanners]

Hey thanks for tagging your repo in my post: https://dev.to/mishmanners/four-projects-to-contribute-to-this-hacktoberfest-pep

I came here to read all about your project and couldn't help but make some fixes. You have some spelling errors, and a couple of sentences that didn't make sense. Fixed them all up. Also, open source is two words :wink:

I didn't do it for the giveaway. It did it for the community.
