Thank you for your contribution. Some notes:

1. Do not enter site_url if it is not a website or similar
2. Some names do not match the repository
3. In the name field, replace the - character with a space

I should fixed everything as you reported.

For site_url I started from another project where I saw that it was the same url for the repository so I did the same.
