+# Dergchat
+
+This is Dergchat, a small chat client for the XMPP protocol. It is written in Rust, based on `xmpp-rs` and Dioxus.
+
+## State of the project
+
+This project is extremely early-days. Do not use this for anything serious.
+
+## Building
+
+Currently, simply open the development shell defined in the flake.nix file; this should give you a shell
+with all the dependencies installed. Then, run `cargo build` to build the project, and `cargo run` to run it.
+
+Installation without Nix is not supported at this time, but you should be able to install the dependencies
+through `apt` or a similar package manager.
