+## Two-way Variables for Mixed-platform Farms
+
+Variables are not just used to point to specific things, like `blender` above.
+They can also tell Flamenco that the path `/media/shared/flamenco` on Linux is
+the same as `S:\flamenco` on Windows, or `/Volumes/shared/flamenco` on macOS.
+This is documented further in [Two-way Variables for Multi-Platform Support][two-way].

+## Custom Job Types
+
+This documentation section focuses on pre-existing variables, `blender` and
+`blenderArgs`. There is nothing special about these. Apart from being part of
+Flamenco's default configuration, that is. When you go the more advanced route
+of creating your own [custom job types][jobtypes] you're free to create your own
+set of variables to suit your needs.
