+There are two ways to build pyodide ifcopenshell Python wrapper wheel.
+
+1. Using pyodide build system (`build_pyodide.yml` does it):
+
+- install prebuilt pyodide build and emscripten environment (see `build_pyodide.sh`)
+- clone IfcOpenShell to `IfcOpenShell` folder
+- create `packages/ifcopenshell` folder that will be used by pyodide build system
+- from `IfcOpenShell` move building recipe `pyodide/meta.yaml` to `packages/ifcopenshell`
+- run `pyodide build-recipes ifcopenshell --install`, it will
+    - execute `meta.yaml` recipe - it will:
+        - copy IfcOpenShell source to build folder `packages/ifcopenhell/build/ifcopenshell-0.8.0`
+        - build ifcopenshell and its dependencies
+        - note that rerunning `pyodide build-recipes` will remove previous build folder and rebuild all dependencies.  
+        The way to avoid it, if build fails, is to use `pyodide build-recipes-no-deps ifcopenshell --continue` instead.
+    - run `setup.py` in `IfcOpenShell` root, producing a wheel in `IfcOpenShell/dist`
+    - copy that wheel to `packages/ifcopenshell/dist`
+    - `--install` it to current build envrionment
+        - copy the wheel next to `dist` folder (in root directory, next to `packages`)
+        - add wheel to `dist/pyodide-lock.json`
+
+2. Build it outside of pyodide build system.
+
+Building inside pyodide build system should be preferred, option to build it outside is useful for debugging purposes,
+since it's pure cmake without any additional moving parts.
+
+- setup pyodide environment, see above
+- clone IfcOpenShell repo next to it to `IfcOpenShell` folder
+- run `python nix/build-all.py -wasm -py-313` in `IfcOpenShell`
+    - it will produce Python package in `IfcOpenShell/ifcopenshell`
+- run `pyodide build`
+    - it will produce a wheel in `IfcOpenShell/dist`
