+_General **WARNINGS**_
+* _The packages included in Tails are carefully tested for security. Installing additional packages **might break the security built in Tails**, so [be careful with what you install](https://tails.net/doc/persistent_storage/additional_software/index.en.html#warning)._
+* _Configuring additional APT repositories **might break the security built in Tails** and might install software that has not even been approved by Debian. Be even more careful with what you install._ 
+* _USB drives break easily, get lost etc. **Make use of [Persistent storage backup feature](https://tails.net/doc/persistent_storage/backup/index.en.html) immediately after registering** new messenger accounts to be able to restore access to accounts and keep backing up regularly (=at least once a week) to minimize data loss. No backup, no mercy. Do not forget to [manually upgrade Tails on your backups](https://tails.net/upgrade/clone/index.en.html#verify-other) as well_

 ## Signal
 Signal Desktop is a slave client for using Signal with an already registered account. Accounts can be registered only with a master client, either an Android or iOS device or using [signal-cli](https://github.com/AsamK/signal-cli) as master. [Signal Desktop will keep linked forever](https://whispersystems.discoursehosting.net/t/will-linked-signal-desktop-keep-working-if-primary-phone-app-isnt-in-use/20465) even when not using/uninstalling the master Signal (e.g smartphone) **if Signal Desktop is used at least once a month, otherwise you'll loose the coupling to your Signal account**. Also re-registering the number decouples your Signal Desktop.
 ### Full Signal registration and usage only on Tails&Tor
