+# Building Noita Proxy
+
+Rust toolchain can be acquired from https://rustup.rs
+
+Another option is to use your distributions rust toolchain, but it might be too old. Proxy is currently built with rustc 1.77.1.
+
+Next, run `cargo build` (or `cargo build --release` for a faster release version) in noita-proxy directory.
+
+You also might need to add steam dynamic library. The easiest way to get one is from the latest mod release.
+
+# Running several instances locally
+
+Address 127.0.0.1:21251 is used to communicate between proxy and local Noita instance by default.
+However, because generally ports can't be used by several apps at once, only one proxy instance can use the default address:port pair.
+
+This address can be changed using enviromental variable NP_NOITA_ADDR. Example (on linux):
+```bash
+NP_DISABLE_STEAM=1 NP_NOITA_ADDR=127.0.0.1:21252 cargo run --release # To start the proxy
+NP_NOITA_ADDR=127.0.0.1:21252 wine noita.exe # To start Noita
+```
