+ * Introduction
+ * ============================================================================
+ *
+ * This plugin enables you to set which tiles are slippery tiles through either
+ * regions or notetags. To use regions, change the parameter setting to which
+ * region ID you would like to associate with a slippery tile.
+ *
+ * ============================================================================
+ * Notetags
+ * ============================================================================
+ *
+ * You can use these notetags to add slippery tiles to your tilesets.
+ *
+ * Tileset Notetag:
+ *   <Slippery Tile: x>
+ *   <Slippery Tile: x, x, x>
+ *   Tiles with terrain ID x will be designated as slippery tiles.
+ *
+ * ============================================================================

+ * - Updated for RPG Maker MV version 1.5.0.
