How to play Wrath of Fire Mountain

About Wrath of Fire Mountain, from BoardGameGeek:

Welcome to the land of Fire Mountain, a primordial land of ever shifting terrain where tribes vie for control using the power of their dinosaurs and the blessing of the volcano. Each turn in Wrath of Fire Mountain, you roll the dice Yahtzee-style, then take actions with the die results. For each volcano, place one of your cave people on the volcano tile; for each egg, place a cave person on the dinosaur-hatching region; for each cave or hut, place a cave person on the matching tile on the 4x4 game board; for each foot, move one of your cave people one space, passing through water (but not stopping there) and avoiding the volcano completely as you occupy the grass and jungle tiles. If you have enough cave people on the dinosaur-hatching region, you can take one of the dinosaurs from this area and add them to your supply, placing them on a cave or hut, then moving them among the tiles like a person. Each dinosaur has a special power, such as letting you roll an extra die, occupying water spaces, or flying to any tile. If you have the most people on the volcano tile (or are tied for the most), you can push the tiles in the row or column with the volcano one space, placing the tile ejected from the 4x4 grid into the now empty space at the end of the row/column. Finally, if all of the volcano spaces are filled, the volcano erupts and players are rewarded for their presence on the land. Look at each separate forest, grass, and water area; whoever has the most presence in an area (or is tied for the most), scores points equal to the number of tiles in the area, then they return all of their pieces in this area to their supply. Players also score based on their presence at the volcano, which is also emptied. After a volcano scoring, if a player has reached a point threshold that's based on the number of players, the game ends, and whoever has the most points wins.
