If you have a Github account, you can simply submit a pull request if you've made a change to the text that you'd like me to consider, or open an issue if there's something you'd like to request but you haven't made the change to the text.
I do review all issues and pull requests that are submitted, but because of health issues it might take me a few days. If you haven't heard back in a week, please drop me a note to remind me!
If you don't have a Github account, please email me at noelle AT noelle.codes to suggest changes to the Guide!
Right now, what the Guide needs most is translations into other languages besides English. My knowledge of most non-English languages isn't strong enough to translate the text myself, and I welcome any multilingual readers to take matters into their own hands! (You may note that this is the lone standing issue that I haven't resolved!)
