Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support ActivityPub. What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.
Pleroma is written in Elixir and uses PostgresSQL for data storage. It's efficient enough to be ran on low-power devices like Raspberry Pi (though we wouldn't recommend storing the database on the internal SD card ;) but can scale well when ran on more powerful hardware (albeit only single-node for now).
For clients it supports the Mastodon client API with Pleroma extensions (see the API section on https://docs-develop.pleroma.social).
If you are running Linux (glibc or musl) on x86/arm, the recommended way to install Pleroma is by using OTP releases. OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it. The installation instructions are available here.
If your platform is not supported, or you just want to be able to edit the source code easily, you may install Pleroma from source.

Currently Pleroma is packaged for YunoHost, NixOS, Gentoo through GURU and Archlinux through AUR. You may find more at https://repology.org/project/pleroma/versions.
If you want to package Pleroma for any OS/Distros, we can guide you through the process on our community channels. If you want to change default options in your Pleroma package, please discuss it with us first.
While we don’t provide docker files, other people have written very good ones. Take a look at https://github.com/angristan/docker-pleroma or https://glitch.sh/sn0w/pleroma-docker.
Community maintained Raspberry Pi image that you can flash and run Pleroma on your Raspberry Pi. Available here https://github.com/guysoft/PleromaPi.
If you ever encounter compilation issues during the updating of Pleroma, you can try these commands and see if they fix things:
mix deps.clean --allmix local.rebarmix local.hexrm -r _build
If you are not developing Pleroma, it is better to use the OTP release, which comes with everything precompiled.
