  QGIS has many different versions and the updates go fast.
  
  In this course we use QGIS 3.22 LTR. LTR means Long Term Release, which means that it is stable and bugs are fixed over a longer time than other versions. There are newer versions, which are great to test new features. However, these versions also might have new bugs and are therefore not recommended for operational use or courses.
  
  There are two ways to install QGIS:
  
  Standalone installer. This is the easiest way, but requires a good internet connection, because you need to download 1GB.
  
  OSGeo4W installer. With this installer, you'll install only what we need, so it needs to download less MBs. However, there are more steps to follow.
  
  Standalone installer
  Watch this video to learn how to use the Standalone installer.
