I'd read that as 1.006 which means its done. Strictly speaking you should take another reading in 2-3 days to check it hasn't gone any lower (if it doesn't move over 2-3 days you know its finished fermenting as it hasn't moved).
Worth leaving another few days or a week before bottling/kegging even if it is done fermenting. The yeast cleans up after itself once finished fermenting and the beer will clear a bit more if left a little longer so you get a clearer beer, faster in the bottle/keg.
Good, low final gravity that, well done !
