+## How can disk space be recovered?
+
+Disk space can be freed in the VM by removing containers or running `docker system prune`.
+However, it will not reflect on the host on Colima versions v0.4.x or lower.
+
+### Automatic
+
+For Colima v0.5.0 and above, unused disk space in the VM is released on startup. A restart would suffice.
+
+### Manual
+
+For Colima v0.5.0 and above, user can manually recover the disk space by running `sudo fstrim -a` in the VM.
+
+```sh
+# '-v' may be added for verbose output
+colima ssh -- sudo fstrim -a
+```

 ## Are Lima overrides supported?
 
 Yes, however this should only be done by advanced users.
