(I'm creating a starting guide post here. Have patience, it will take some time...)
Disclaimer: I am new to Lemmy like most of you. Still finding my way. If you see something that isn't right, let me know. Also additions, please comment!
Welcome!
Welcome to Lemmy (on whichever server you're reading this)
About Lemmy
Lemmy is a federated platform for news aggregagtion / discussion. It's being developed by the Lemmy devs: https://github.com/LemmyNet
About Federation
What does this federation mean?
It means Lemmy is using a protocol (Activitypub) which makes it possible for all Lemmy servers to interact.
You can search and view communities on remote servers from here
You can create posts in remote communities
You can respond to remote posts
You will be notified (if you wish) of comments on your remote posts
You can follow Lemmy users/communities on other platforms that also use Activitypub (like Mastodon, Calckey etc) (There's currently a known issue with that, see here
Please note that a server only starts indexing a server/community once it has been interacted with by a user of this server.
A list of Lemmy servers and their statistics can be found at FediDB
Quick start guide
Account
You can use your account you created to log in to the server on which you created it. Not on other servers. Content is federated to other servers, users/accounts are not.
Searching
In the top menu, you'll see the search icon. There, you can search for posts, communities etc.
You can just enter a search-word and it will find the Post-titles, post-content, communities etc containing that word that the server knows of. So any content any user of this server ever interacted with.
You can also search for a community by it's link, e.g. !Netherlands@lemmy.nl. Even if the server hasn't ever seen that community, it will look it up remotely. Sometimes it takes some time for it to fetch the info (and displays 'No results' meanwhile..) so just be patient and search a second time after a few seconds.
Creating communities
First, make sure the community doesn't already exist. Use search (see above). Also try https://browse.feddit.de/ to see if there are remote communities on other Lemmy instances that aren't known to Lemmy.world yet.
If you're sure it doesn't exist yet, go to the homepage and click 'Create a Community'.
It will open up the following page:
Here you can fill out:
Name: should be all lowercase letters. This will be the /c/
Display name: As to be expected, this will be the displayed name.
You can upload an icon and banner image. Looks pretty.
The sidebar should contain things like description, rules, links etc. You can use Markdown (yey!)
If the community will contain mainly NSFW content, check the NSFW mark. NSFW is allowed as long as it doesn't break the rules
If you only want moderators to be able to post, check that checkbox.
Select any language you want people to be able to post in. Apparently you shouldn't de-select 'Undetermined'. I was told some apps use 'Undetermined' as default language so don't work if you don't have it selected
Reading
I think the reading is obvious. Just click the post and you can read it. SOmetimes when there are many comments, they will partly be collapsed.
Posting
When viewing a community, you can create a new post in it. First of all make sure to check the community's rules, probably stated in the sidebar.
In the Create Post page these are the fields:
URL: Here you can paste a link which will be shown at the top of the post. Also the thumbnail of the post will link there. Alternatively you can upload an image using the image icon to the right of the field. That image will also be displayed as thumbnail for the post.
Title: The title of the post.
Body: Here you can type your post. You can use Markdown if you want.
Community: select the community where you want this post created, defaults to the community you were in when you clicked 'create post'
NSFW: Select this if you post any NSFW material, this blurs the thumbnail and displays 'NSFW' behind the post title.
Known issues can be found in the beforementioned post, one of the most annoying ones is the fact that post/reply in a somewhat larger community can take up to 10 seconds. It seems like that's related to the number of subscribers of the community.
I'll be looking into that one, and hope the devs are too.
I'm a dev interested in getting involved. I've followed on GitHub and I'm about to start diving into the various repos. Where is development being coordinated?
Github is the right place s most of the development is discussed in the issues and PRs there. There's also the Matrix space https://matrix.to/#/#lemmy-space:matrix.org which has various chat rooms regarding Lemmy/Jerboa development.
Also you're... me? :D At least our taste in usernames is very similar.
So funny story. I just spent 20 minutes trying to figure out why I couldn't log in. I hadn't realized I typoed Colonel. I didn't do a pw request - just logged in with the email instead - but apologies if you got spammed with login attempts lol. Nice username! I'm not familiar with Matrix so I'll check it out and join.
I've been reading through the GitHub docs. Sounds like the Matrix space is probably what I'm looking for. PRs and issues are great for discussions specific to them but I feel awkward submitting feature requests as issues just to open discussion, ya know? Or like, discussing how to coordinate time so we don't have multiple people tackling the same thing - or could work together on them if so. So probably that. Thanks and I'll see ya there! I'll use a different username to avoid confusion lol
