I am very happy that you found this page and are willing to contribute to this project.
The following is a short incomplete list of things I am most in need of help with.
No matter how many times I reread my own writing I find errors. I also think my writing is at times clucky and hard to read. If you can make my content better please submit a pull request.
If any of the explainations I have are incorrect or incomplete please submit a pull request. I try my best to provide accurate information but I am very capable of making mistakes.
