+# BIMR
+
+[BIMR](https://bimr.net) is a text-based Building Information Modeler.
+
+This is the central repository for building BIMR from source.
+
+## Prerequisites
+
+- Rust with the `wasm32-unknown-unknown` target
+- Node.js (latest) and pnpm
+- `wasm-bindgen-cli` (0.2.114) and `wasm-opt`

+## Serve
+
+Serve the web editor
+
+```bash
+make serve 
+```
