 ### Usage
 
+If you have a TeamTalk SDK license, you can pass it when instantiating the bot so
+the SDK is initialized with your credentials. Both `license_name` and
+`license_key` must be provided together; otherwise the library raises a
+`ValueError`. The TeamTalk SDK license is process-wide, so all bot instances in
+the same process must reuse the same credentials.
+
 ```python
 import pytalk
 
-bot = pytalk.TeamTalkBot()
+bot = pytalk.TeamTalkBot(
+    client_name="PyTalk",
+    # Optional: apply your TeamTalk SDK license if you have one
+    license_name="Your Company",
+    license_key="XXXXX-XXXXX-XXXXX-XXXXX",

 Quick Start
 -----------
 
+If you own a TeamTalk SDK license, you can supply it at initialization so the
+SDK is unlocked with your credentials. Both ``license_name`` and
+``license_key`` must be provided together, and the license is process-wide, so
+all bot instances must share the same credentials. Otherwise, you can omit
+them.
+
 To quickly get started with Pytalk, you can use the following code snippet:
 
 .. code-block::
 
     import pytalk
 
-bot = pytalk.TeamTalkBot()
+bot = pytalk.TeamTalkBot(
+    # Optional: apply your TeamTalk SDK license details if you have them
+    license_name="Your Company",
+    license_key="XXXXX-XXXXX-XXXXX-XXXXX",
+)
