+# Otter
+
+Otter is a standalone implementation of the [Gpodder.net
+API](https://gpoddernet.readthedocs.io/en/latest/). Its goal is to be a
+lightweight self-hostable alternative to [gpodder.net](https://gpodder.net) for
+synchronizing podcast subscriptions and episode states between compatible
+clients.

+## Easy to install
+
+Otter is distributed as a single statically compiled binary, allowing it to be
+used in any Linux-based context, be it as a Systemd service or in a Docker
+container.
+

+
+## Simple to configure
+
+Only a small amount of configuration is required to get Otter up and running,
+all of which can be done from a config file, environment variables, or CLI
+arguments.
+

+
+## Multi-user
+
+Otter supports multiple users and provides functionality for making your server
+either public or private, along with easy ways of inviting new users to your
+server. Host it for yourself, your friends, or start a public instance!
