+# Features
+
+1. Compare combined item costs of players based on their position
+    * Drag & Drop champion images to re-order players in their respective teams
+2. Compare combined item costs of both teams
+3. Choose between two different type of gold stats:
+    1. "Total Gold" - The combined worth of **all** items in a players inventory
+    2. "Non Consumable Only" - The combined worth of items excluding one-time consumable (such as potions and wards)
+4. Display every player's stats as well as their "unspent" stats, i.e., kills/assists/deaths since they last purchased an item
+    * _GoldDiff_ has no access to the current amount of unspent gold; unspent stats allow for a rough estimation of how much gold players have up their sleeves
+    * Both the player stats as well as the unspent stats can be turned off in the settings
+    * Also applies to the overall team stats
+5. "Power Play" indicator for Baron Nashor and the Elder Dragon
+    * _GoldDiff_ displays the relative growth of the gold advantage while the Baron or Elder Dragon Buff is active - much like in pro play!
+6. Inhibitor respawn timers
+7. Gold advantage over time (Gold Chart)
+    * _GoldDiff_ visualizes the gold differences over the duration of your game
+
+### Limitations
+
+Currently, _GoldDiff_ supports only games played on Summoners Rift in the classic 5 vs. 5 game mode (including Blind Pick, Draft Pick, Ranked Solo/Duo, Team Ranked, Custom Games, Practice Tool).
+Other maps/game modes, such as ARAM oder special event modes, are currently not supported.
