+To test FUSE with xfstests¹:
+
+1.  copy the `mount.fuse.passthrough` file into
+  `/sbin` and edit the `PASSTHROUGH_PATH`, `SCRATCH_SOURCE` and `TEST_SOURCE` variables as needed.
+
+2.  Make sure that the `SCRATCH_SOURCE` and `TEST_SOURCE` directories
+exist.
+
+3. Copy `local.config` into your xfstests directory
+
+Tests can then be run with e.g.:
+
+```sh
+# make
+# sudo ./check -fuse -b
+```
