 With `lfs --json` (shortened in `lfs -j`) you get a JSON structure that can be used in other programs.
 
-# Raw output
+# JSON output
 
-Here's a sample, that I could get with `lfs -j > disks.json`:
+The normal output is an array of all filesystem matching the filter.
+
+In order to make a sample fitting this site, I extracted the first filesystem with
+
+```bash
+lfs -j | jq '.[0]' > disk.json
+```
+
+Here it is:
 
 ```JSON
