The manual was written for QGIS version 3.10 (A Coruna), which is the current Long Term Release version. Because there are enough differences between versions you should download and install 3.10 if you are taking the workshop.
- MS Windows users: QGIS 3.10 (32 bit) - or - QGIS 3.10 (64 bit)
- MAC users (OS X High Sierra and newer): Download and install the dmg image QGIS 3.10.
- Linux users should consult the QGIS download page and follow the instructions to download the 3.10 release version for your distro.
