+    #First phase: Building
 
-    #title
+    In
+    this phase, first the blue and then the red player can build, upgrade, and destroy
+    their towers. The players can choose a tower from the bottom-side bar and place
+    it on any of the highlighted squares if they have enough money. On the right
+    side of the screen are shown the stats of the selected tower. If a tower from
+    the gamefield is selected, the players can also upgrade it, or destroy it for
+    a refund.

+    #Second phase: Unit training
 
-    #title
+    In the second phase, following
+    the team order stated in the first phase, the players can buy units and plan
+    their route to the enemy''s castle. Choosing a unit is similar to choosing a
+    tower, but after clicking on one of them from the bottom bar, if the player has
+    enough money, the unit gets queued up in one of the barracks and will be spawned
+    in the last phase. When clicking on one of the barracks, the players can add
+    a checkpoint to those units'' paths that will spawn from that barrack by clicking
+    on a reachable tile with a left-click, or remove a checkpoint with a right-click.
+    The brightness of the checkpoints indicates their order: the brightest checkpoint
+    is the last before the enemy castle. Note that the players have the same budget
+    for the towers and the units, and they have to manage it accordingly to succeed.

+    #Third
+    phase: Attacking
+
+    In this phase, the players can only inspect their fight.
+    The units that are left alive from the previous rounds continue their journey
+    into the enemy base, while the ones purchased in this round start to deploy from
+    the barracks. When a unit reaches its destination, it damages it and gets destroyed.
+    If one castle gets destroyed until the end of the round, the enemy team wins.
+    If both get destroyed, the game is tied.
+
+    When hovering the cursor over
+    a unit or a castle, a healthbar appears, showing its current health.'
