Notes

The 2 artificial relay is forcing to 3NT;
the 2 artificial relay is invitational: partner declines with 2
In third position, these weak openings may have one less card than stated, might be weaker or stronger than the nominal range and may conceal a four-card major
After 1 – 1/1, opener rebids 2/2 to show both minors
(2 showing three-card support for responder's major).
After 1 – 1NT, opener rebids 2NT to show both minors.
