Where can I report bugs which I find on CI4 (official) Documentation?

For example here https://codeigniter.com/user_guide/helpe...#url_title

This line: $url_title = url_title($title, 'underscore');

should be corrected to (if I'm not wrong?) $url_title = url_title($title, '_');

Here is good, that part have accidentally been copied from CI3. I will fix that.

You can use our Github (if you have an account), if you find any more bugs.
https://github.com/codeigniter4/CodeIgniter4/issues

And always feel free to jump in and make the corrections and submit a PR! We love that.
