+## DEPRECATION NOTICE
+
+I no longer use Truenas for the following reasons
+
+1. Upgrades breaking VMs
+2. Upgrades breaking app compatibility
+3. Opaque process for backing up and restoring the "ix-*" directories
+4. Opaque process for snapshotting app data
+5. Difficulty decrypting nested datasets with multiple keys
+6. Truenas not exporting the correct JSON key format to decrypt nested datasets
+7. Lack standard support for libvirt
+8. Incredibly slow loading of snapshots in the UI
+
 ## Bios settings
 
 You can check the bios version with `dmidecode -t bios -q`
