 ## Setup development environment
 
 ### Install ultimateALPR SDK
-#### Use already built wheel
-I have already built the ultimateALPR SDK for x86_64 and ARM64 and included the python3.10 wheel in the wheel folder.
-You can install the wheel using : ``pip install wheel/*.whl``
 #### Manually build the wheel
 If you want to build the wheel yourself, you can use the ``build_and_setup_ultimatealvr.sh`` script. It will create a new
 directory ``tmp`` and build the wheel in there. It also includes the assets and libs folders needed when developing.
+> [!IMPORTANT]
+> Make sure to install the package python3-dev (APT) python3-devel (RPM) before running the build and setup script.

 ### Copy necessary files/folders
-Then you need to copy the ``assets`` and ``libs`` folders to the same directory as the script.

-If you built the wheel in the previous step, you can copy the ``assets`` and ``libs`` folders from the ``tmp`` directory.
-If you used the already built wheel, you can find the 'assets' and 'libs' folders on the [GitHub repository](https://github.com/DoubangoTelecom/ultimateALPR-SDK/tree/master/assets)
