+  curl --proto '=https' --tlsv1.2 -sSf \
+    -L https://install.determinate.systems/nix \
+    | sh -s -- install
+```
+
+Then, run one of the following commands to automatically build and run QGIS.
+
+Run QGIS from Git:
+
+```sh
+nix run github:qgis/QGIS#qgis             # run latest version from master
