Consider adding a doc page for using QGreenland 'offline' / in the field. It would cover topics like:

• Disclaimer
• Recommend downloading the QGIS user manual in advance for reference. (https://docs.qgis.org/3.28/pdf/). We have some doc pages that cover common operations (e.g., spatial selection of vector features) but these are no substitute for a full QGIS user-guide
• link to other relevant docs, e.g., the "Creating New Vector Layers from Scratch" how-to
• ?
