+Naming Convention
+=================
+
+Catalyst introduces a standardized naming convention for all asset pairs 
+trading on any exchange in the following form:
+
+
+    **{market_currency}_{base_currency}**
+
+Where {market_currency} is the asset to be traded using {base_currency} as 
+the reference, both written in lowercase and separated with an underscore.
+
+This standardization is needed to overcome the lack of consistency in the 
+naming of assets across different exchanges, and making it easier to the user
+to refer to the asset pairs that you want to trade.
+
+Catalyst maintains a `Market Coverage Overview <https://www.enigma.co/catalyst/status>`_ 
+where you can check the mapping between Catalyst naming pairs and that of each 
+exchange. Catalyst will always expect in all its functions that you will refer to 
+the asset pairs by using the Catalyst naming convention.
+
+If at any point, you input the wrong name for an asset pair, you will get an error 
+of that pair not found in the given exchange, and a list of pairs available on that exchange:

+In the example above, exchange Poloniex does not use USD, but uses instead the 
+USDT cryptocurrency asset that is issued on the Bitcoin blockchain via the Omni
+Layer Protocol. Each USDT unit is backed by a U.S Dollar held in the reserves of 
+Tether Limited. USDT can be transferred, stored, and spent, just like bitcoins 
+or any other cryptocurrency. Given its 1:1 mapping to the USD, is a viable alternative.
