-Lang is 2 sumbols code, i.e. en, ru, be.
+Lang is 2 symbol code, i.e. 'en', 'ru', 'be'.
 
 How to install:
     1) cabal install
 
 Usage example:
-    1) gtc en ru test
-    2) gtc en ru This is test
+    $ gtc en ru test
+    $ gtc en ru This is test
+    $ gtc en ru
+    <interactive line-based mode>
