 µBlock is its own thing, it doesn't try to be Adblock Plus or any other.
 
-Regular expression-based filters are not supported. At time of writing I see three such filters in _EasyList_, and none in _EasyPrivacy_. So rather uncommon. I may support them if there is really a need, but only for those which will have the `domain` filter option set: otherwise it's just impossible to implement efficiently such filters, and µBlock won't encourage their use by supporting these. For all the instances I have seen, it is possible to translate them into more efficient non-regex-based filters.

-**Read carefully:** Not supporting regex-based filters has absolutely **nothing** to do with µBlock being more efficient than ABP. It's a myth. It's BS. It's pure disinformation. There is no truth to this. If you hear that somewhere, you are being completely dis-informed.
+For all the instances I have seen, it is possible to translate them into more efficient non-regex-based filters. For example, the following regex-based filters found in _EasyList_:

 The `$document` filter option is not supported, see [issue #405](https://github.com/gorhill/uBlock/issues/405). At time of writing, I see 10 such filters in _EasyList_.
