+
+h3 Basic rules
+
+p.
+  There are no captures in this game: only unions of pieces,
+  which are released when replaced by another friendly piece.
+  The goal is to create an union with the enemy king.
+  I like to think of unions as "pieces dancing together", so both
+  terms will be used on this page.

+  figcaption Some union pieces.
+
+p.
+  At each turn, a player chooses either one of his pieces or an union piece;
+  let's write this piece A.
+ul
+  li.
+    Case 1: A is a dancing piece. Then, it's only allowed to move
+    to a vacant square according to our piece's type.
+  li.
+    Case 2: A is a standard piece.
+    It can then be moved anywhere but on our own (normal) pieces.
+    "Capturing" an enemy piece creates an union composed of both pieces.
+    "Capturing" an union releases our piece formerly in union,
+    which has to be moved immediately by the same player. It can in turn
+    release another piece, thus following a chain of unions.
+
+p
+  | This may appear confusing at first reading, but is simpler than it seems.
+  | See for example this 
+  a(href="https://www.youtube.com/watch?v=tQ2JLsFvfxI") gameplay video
+  | , or another one from the same YouTube channel.

+
+h3 Special moves, additional notes
+
+p.
+  "Capturing" an union en passant releases our dancing piece from the
+  intermediate square.
+
+p Promotion occur when any pawn (in union or not) reaches its final rank.
+
+p.
+  Attacks on the king are ignored in this implementation: you can run
+  or remain into "check". So, castling conditions are quite permissive.
+  Also, if you form an union with your king but end dancing with the
+  other king on the other end of the chain, the game is a draw. 
+  span.warning This does not follow (at all) the official rules.

+    Left: Bd3(+) can be covered by Right: h6xg5 (releasing the knight), Ne4.
+
+p.
+  Canceling an union move is forbidden. For example if a bishop is
+  dancing with a queen, and makes the move e5 to g3, the other player cannot
+  move it back to e5 just after. This is also non-official.
