+Based on @celogeek's instructions: https://github.com/darodi/kcc/issues/4#issuecomment-1364553511
 
-I figure out a way to build it on M1.
-Here the result: https://static.celogeek.com/KCC/M1/KindleComicConverter_osx_5.5.3b17.dmg
+# Requirements
+- [Homebrew](https://brew.sh) installed
+- Python 3.9-3.11. In this tutorial, we will use Python 3.9. If you use other versions, remember to change it in the commands.
 
-So to do that:
-I use pyenv.
+# Steps
+1. Create a new Python environment.
 
-So for the repo
 ```
-pyenv install 3.9.16
-pyenv virtualenv 3.9.16  kindle
-pyenv activate kindle
+python3.9 -m venv kindle
+```
 
-brew install pyqt@5 boost-python3 cmake
-export PYTHONPATH=/opt/homebrew/Cellar/pyqt@5/5.15.7_1/lib/python3.9/site-packages
-pip install -r requirements.txt
-pip install pyinstaller 
+3. Activate new environment.
+
+```
+source kindle/bin/activate
+```
+4. Install dependencies from Homebrew. Remember the `pyqt@5` version installed. At the time of writing, the latest version is `5.15.7_2`.
+
+```
+brew install pyqt@5 boost-python3 cmake node
+```
+
+5. Install `appdmg` for packaging.
+
+```
 npm install -g appdmg
 ```
 
-You need a m1 compatible version of 7z:
+6. Bind `pyqt@5` to Python. Change the version number of `pyqt@5` if necessary.
+
+```
+export PYTHONPATH=/opt/homebrew/Cellar/pyqt@5/5.15.7_2/lib/python3.9/site-packages
+```
+
+To check if `PyQt5` is correctly binded, run `pip freeze | grep PyQt5` and see if `PyQt5` shows up.
+
+7. In repo folder, install Python dependencies and `pyinstaller`.
+
+```
+pip install -r requirements.txt
+pip install pyinstaller 
+```
+
+8. Compile 7z.
+
 ```
 git clone https://github.com/p7zip-project/p7zip.git

-rm -rf dist
 python setup.py build_binary
