If you want to help write content, I created a long wishlist of things I would like better documented or at all.
The README on the Github repo is a good place to start.
If you want to bring up an issue about a page or the site generally.
Create an Issue: If you are familiar with github, you can create an issue on the repo.
There are many equivalent ways of doing this, depending on your communication style:
Edit this page: Every page has a link in the upper right corner that can click on to see the page in github.
Comment: At the bottom of every article, there is a comments section that is tied to github issues.
Email: If you do not want to use github, you can interact with the contributors by emailing tshark_dev[АТ]fire.fundersclub.com. This will make a github issue that functions like an email chain from your perspective.
Contact: If you do not want your issue to be public, you can contact me directly at rj[АТ]tshark.dev
Support this website to get a link to a pdf that stays current with new content.
