-### How can I transfer a Briar account from my Android device?
-
-By using [_adb_](https://developer.android.com/studio/command-line/adb),
-you can copy the database and keys from a Briar Android installation.
-Note that your smartphone needs to be rooted for this.
-
-You shouldn't use this technique to clone your Briar account to another device and
-then use the same account on both devices. If you do this, you open up yourself to many
-possible threats. See
-[this comment on Briar's issue tracker](https://code.briarproject.org/briar/briar/issues/110#note_34386)
-for more information. Therefore, make sure to delete the old copy
-of your Briar account after you've transferred it to another device to protect
-yourself against attacks circumventing forward secrecy.
-
-In case you just want to transfer contacts from one account to another,
-better use the "contact introduction feature" which is already available on Android
-devices and which is planned to land in python-briar-wrapper, too.
-
-You can either use the script at 
-[tools/copy-db-from-android.sh](tools/copy-db-from-android.sh) or do it manually:
-
-1. Start _briar-gtk_ and register a dummy account. This will create
-the needed directory structure at _~/.briar/_. Close the program afterwards.
-2. Enable _adb_ on your smartphone and give it root permissions.
-3. Connect via _adb_ and gain root permissions using `adb root`.
-4. Copy all important files using `adb pull`:
-_/data/data/org.briarproject.briar.android/app_db/db.mv.db_,
-_/data/data/org.briarproject.briar.android/app_key/db.key_,
-_/data/data/org.briarproject.briar.android/app_key/db.key.bak_
-5. Replace the respecting files in _~/.briar/db_ and _~/.briar/key_.
