 ## "abra server ls" shows the wrong details?
 
-TODO.
+You can use `abra server rm` to remove the incorrect details. Make sure to take a backup of your `~/.abra/servers/<domain>` first.
+
+However, if you have Docker installed on the same machine you have `abra`, then there might be some confusion. If you run `docker context ls` you'll see that Docker uses context connection strings also. `abra` simply uses this approach. Sometimes, your Docker defined context details & your `abra` context details can get out of sync. You can use `docker context rm` to resolve this.
+
+If you need to create a new context from Docker, you can do:
+
+```
+docker context create <domain> --docker "host=ssh://<user>@<domain>:<port>"
+```
+
+(This is what we used to before we wrote `abra` to make it more convenient.)
