Interacting with the community is important, so we can help out each other, build stuff together and overall accelerate development. Here's an overview of the various ways to interact with each other. At the bottom are the wiki pages tagged with
Matrix and IRC
If you are new to the project, a good place to say hi are the various live chat rooms that you can connect to with matrix and irc clients (there's also a matrix web browser client, so no need to install anything). We have various channels ranging from offtopic, to development chatting, to lowlevel firmware hacking.
Mostly used for technical development discussions, bug reports and feature requests (e.g. pmbootstrap, pmaports). But also meta-discussions about the direction the project is heading, new blog posts, about the infrastructure and what not (the postmarketos.org project). GitLab has a nice all issues page.
It's possible to get e-mail notifications for new issue posts by opening the whole postmarketOS GitLab organization (alternatively, click on a project from that page). Then find the Notification Settings below the logo, where it probably says "Global" if you did not modify it. Click it and switch to your desired level (e.g. "Watch").
People with general interest in the project hang out in the Subreddit (not necessary developers), and new posts show up in their news feeds as they are browsing Reddit. Good place to share cool new experiments you are doing, ideally with photos or videos. Or posting links to topics that relate to postmarketOS, but do not directly come from the postmarketOS community.
Mastodon and Twitter
If you are into social networks with short message feeds, have a look at:
How about $yourfavoritemedium?
This is the website you are viewing right now. Use it to document everything you figure out as you are porting or using postmarketOS on your device. This helps the next person, and it wouldn't be the first time that someone started a device specific port, and another person came with the same device and built upon it. Wiki related discussions are not done in the wiki (like it is done in most other MediaWiki installations), but instead in the wiki project over at GitLab. The GitLab project also serves as full backup of the wiki (updated hourly).
