 The primary use-case for BubbleBox is running applications that you do not trust enough
 to give them full access to hour home directory, and in particular the secret keys stored there.
-In this regard it is similar to [firejail] and [bubblejail], but less powerful and in exchange hopefully easier to configure.
 BubbleBox is based on [bubblewrap] and [xdg-dbus-proxy] which do all of the heavy lifting.
 
+The goals of this project are similar to [firejail], but I found firejail's configuration to be extremely hard to maintain and debug.
+BubbleBox is meant for people that are comfortable editing its Python source code to adjust it to their needs;
+if you are looking for something with a more out-of-the-box experience, try [bubblejail].
