 ### Double puppeting (recommended)
 
-You can replace the Matrix puppet of your Slack account with your Matrix account. When you do so, messages that you send from other Slack clients will be sent from your Matrix account instead of the default puppet user.
-
-How to get virgin Access-token: Use <https://gitlab.com/vurpo/matrix-login/> for currently most effortless method.
-
-As with the Slack account login, you must do this in a private chat with the bridge bot.
-
-- Log in with `login-matrix <access token>`
-- After logging in, the default Matrix puppet of your Slack account should leave rooms and your account should join all rooms the puppet was in automatically.
