I've now pushed our new Wiki to be the default one. While it's far from ready to be considered a definitive resource, I think it is an improvement over the old one. Further -- I think that the only way it's going to improve is if it is publicly visible and users can work on it.
I have added some posts to it and a few team members have done some work on it, but we unfortunately have a limited amount of time. We would greatly appreciate it if the community could help further the Wiki.
The new Wiki is built on top of Discourse: so editing it is as simple as editing or creating a new post here. If this is something you think you'd be interested in, please let us know here and we will get you set up.
Creating a wiki post
Create a post in the General category with the tag [Wiki] in the title.
We will then read it and move it to the wiki category and it will then go live on https://osmc.tv/wiki.
The wiki is read only so we can vet posts before they go live on https://osmc.tv/wiki.
Contribute to a current wiki post
If you want to add/correct something on a wiki post you can locate it on https://osmc.tv/wiki and press "Make this page better" in the top right corner.
It will send you to the corresponding post on discourse where you can reply with corrections or new lines, which we then will add to the post.
