+If you selected an alternate flavour on installation, 
+you _may_ need to specify `--flavour`, in the same way as 
+[when installing](../../installation/otp_en#detecting-flavour).

 ## For from source installations (using git)
 
 1. Go to the working directory of Akkoma (default is `/opt/akkoma`)

 Use the following mapping to figure out your flavour:

 Other similar distributions will _probably_ work, but if it is not listed above, there is no official
 support.
