Hint
Looking for documentation of versions newer than the 3.34 Long Term Release? Have a look at the testing docs.
Note
QGIS documentation is available in various languages and versions. Expand the QGIS Documentation menu at the bottom of the sidebar to see the list.
Welcome to the official documentation of QGIS, the free and open source community-driven GIS software! If you are new to this documentation, the table of contents below and in the sidebar should let you easily access the documentation for your topic of interest. You can also use the search function in the top left corner.
Besides the online documentation, the QGIS project also provides materials that you can download for offline reading. They are accessible from the QGIS Documentation menu at the bottom of the sidebar, as:
HTML zipped files that you can extract and use as paths from within the software
PDF files
