 #### Steam doesn't work.
-Steam doesn't work out of the box due to security features in the shim kernel preventing the `bwrap` library from working. See [issue #12](https://github.com/ading2210/shimboot/issues/26#issuecomment-2151893062) for more info. 
+Steam should be installed using the `sudo apt install steam` command, however it doesn't work out of the box due to security features in the shim kernel preventing the `bwrap` library from working. See [issue #12](https://github.com/ading2210/shimboot/issues/26#issuecomment-2151893062) for more info. 
 
 To get Steam running, install and run it normally. It will fail and show a message saying that "Steam now requires user namespaces to be enabled." Run `fix_bwrap` in your terminal, relaunch Steam, and it should be working again.
