+# forge
+A simple remote build system. Consists of a client (`forge-client`) and server (`forge-server`).
+
+## Server
+On first run, `forge-server` will create a configuration file for you in the default location (e.g. `~/.config/forge/config.toml`).
+Use this to configure options, such as the IP & port to bind on, and whether to use authentication (along with a password).
+
+Authentication will use *Argon2id* to hash and verify passwords.
+
+Actually building stuff is a **WIP**.
+
+## Client
+Fully **WIP**. Right now it just sends test data.
+
+Eventually, everything will be specified via command arguments, using [clap](https://lib.rs/crates/clap) for parsing.
+
