I assume this is what is meant:

                       | Works Perfectly | Mostly Works | Has Lots Of Bugs
    -------------------+-----------------+--------------+-----------------
    Default Install    |                 |              |
    -------------------+-----------------+--------------+-----------------
    With Add-Ons       |       X         |              |
    -------------------+-----------------+--------------+-----------------
    Major Config Work  |                 |              |

i.e. Declare its working quality after the install is done. The install may take multiple steps. (In this case, copying some files over, apparently.)
