 Getting Minecraft Player Information from Mojang API.
 
 ## Usage
-1. Add the mcuuid.py file to your Python path.
+1. `pip install mcuuid`
 2. Use the module like this:
 
+### API
 ```
-from mcuuid import GetPlayerData
+from mcuuid.api import GetPlayerData
 
-player = GetPlayerData(username)
+player = GetPlayerData(identifier)
 
 if player.valid is True:
     uuid = player.uuid
     name = player.username
 ```
 
-Read `test.py` for some explaination.
+Identifier can be a username or a UUID.
 
-When `username = "gronkh"`:
+When `identifier = "gronkh"`:
 `uuid` will be `"a2080281c2784181b961d99ed2f3347c"`
 and `name` will be `"Gronkh"`
 
+
+```
+player = GetPlayerData(identifier, timestamp)
+```
+
+Some names are time-sensitive. (When they are changed)
+So you can choose a special time.
+
+It even works with UUIDs. They respond the username at the given time.
+
+### Tools
+Syntax check of username
+```
+from mcuuid.tools import is_valid_minecraft_username
+
+if is_valid_minecraft_username('gronkh'):
+  print('Valid')
+```
+
+Syntaxcheck of UUID
+```
+from mcuuid.tools import is_valid_mojang_uuid
+
+if is_valid_mojang_uuid('a2080281c2784181b961d99ed2f3347c'):
+  print('Valid')
+```
