+# Installation - (x86_64) Windows (with WinPython), build with MSYS2
 
 ## Prerequisites
 
 - Download and install [WinPython](https://winpython.github.io)
+
+## From wheel
+
+- Download latest wheel from [LASP releases](https://code.ascee.nl/ASCEE/lasp/releases/latest/) and
+download the latest `.whl`. Then install with `pip`.
+
+## From source
+
 - Download and install [MSYS2](https://msys2.org). Make sure to install the
   x86_64 version.
-- Download and install [Git for Windows](https://git-scm.com)
-
 - When unzipping WinPython, make sure to choose a proper and simple path, i.e.
   C:\winpython
-- Append C:\winpython\ to the PATH environment variable.
-- Run Python and install Pybind11
-    - `python -m pip install pybind11`
-
-
-- Open a msys2 **MINGW64** terminal. And run:
-
-    - `pacman -S git`
-
-- Then clone the LASP repo:
-
-    - `git clone https://code.ascee.nl/ascee/lasp`
-    - `cd lasp`
-
-- Configure MSYS2 further, and run cmake:
-
-    - `scripts/install_msys2_buiddeps.sh`
-    - `scripts/configur_cmake_msys2.sh`
+- Download and install [Git for Windows](https://git-scm.com)
+- Open an MSYS2 **MINGW64** terminal, and install some tools we require:
+  - `$ pacman -S git`
+- Create a new virtualenv:
+  - `$ /c/winpython/<py-distr-dir>/python.exe -m venv venv`
+- Add the venv-python to the path (eases a lot of commands)
+  - `$ export PATH=$PATH:~/venv/Scripts`
+- Install `build`:
+  - `$ pip install build`
+- Clone LASP:
+  - `$ git clone --recurse-submodules https://code.ascee.nl/ascee/lasp && cd lasp`
+- If run for the first time, we have to install the libraries we depend on in
+  MSYS2 (this only has to be done on a fresh MSYS2 installation):
+  - `$ scripts/install_msys2_builddeps.sh`
+- Copy over required DLL's to be included in distribution:
+  - `scripts/copy_windows_dlls.sh`
+- And... build!
+  - `pyproject-build`
+- Lastly: the generated wheel can be installed in the current virtualenv:
+  - `pip install dist/lasp*.whl`
