+
+### Flea market
+
+_/fleaMarket_ endpoint for game shop operations.
+
+- _/fleaMarket_ and _/fleaMarket/:_id_ GET: get all flea market items available or info about specific one
+- _/fleaMarket/buy_ POST: buy an item from the flea market for the logged-in user clan = move an item from market to stock. 
+  Notice, that it will start the voting process between the clan members, since the money spent on the item are common for all clan members.
+  There are no restrictions of who can buy an item, as long as this player is within some clan.
+  The min acceptance percent for an item to be purchased is 51.
+  Here is the process diagram of the [buying process](https://github.com/Alt-Org/Altzone-Server/blob/dev/doc/img/flea_market/flea_market_items.svg) and here is the diagram of [voting process](https://github.com/Alt-Org/Altzone-Server/blob/dev/doc/img/voting/voting.svg).
+- _/fleaMarket/sell_ POST: sell an item from the flea market for the logged-in user clan = move item from stock to flea market.
+  Notice, that it will start the voting process between the clan members, since the item is common for all clan members.
+  There are no restrictions of who can sell an item, as long as this player is within some clan.
+  The min acceptance percent for an item to be sold is 51.
+  Here is the process diagram of the [selling process](https://github.com/Alt-Org/Altzone-Server/blob/dev/doc/img/flea_market/flea_market_items.svg) and here is the diagram of [voting process](https://github.com/Alt-Org/Altzone-Server/blob/dev/doc/img/voting/voting.svg).

+- _/voting_ and _/voting/:_id_ GET: get info about logged-in player votings, where he/she can participate/participated.
+- _/voting_ PUT: send a vote of the logged.in player
+
+Notice that in order to get hot updates of the ongoing voting(s) a MQTT protocol must be used. Topics for voting updates are:
+ - /clan/{clan_id}/voting/# for all clan votings
+ - /clan/{clan_id}/voting/{voting_id} for a particular voting
+

+
+### Logged-in user info retrieval
+
+As it was requested for a long time the endpoint, _/profile/info_ GET, for retrieving data of the logged-in user is added.

+
+For the stock they are:

+
+        unityKey: ItemName.ARMCHAIR_RAKKAUS,
+        ...
+    },
+    {
+        unityKey: ItemName.FLOORLAMP_RAKKAUS,
