 In development you might want to enable some settings to make it easier to spot problems. Enabling `track.debug` will log debugging info to the Python logger. You can also add an `on_error` handler to specifically print out the response you’re seeing from our API.
 ```

+def on_error(error, items):
     print("An error occurred:", error)

 track.debug = True
 track.on_error = on_error

+|Settings name|Type|Default value|Description|

+|debug|bool|False|To turn on debug logging|
+|timeout|int|10|Timout for track API calls|
+|max_retries|int|3|Number of API retries in case API call fails due to some error|
+|max_queue_size|int|10000|Max Queue size|
+|on_error|function|None|Callback function which is called whenever an error occurs in **asynchronous** mode

+## Identify
 The `identify` lets you tie a user to their actions and record traits about them. It includes a unique **User ID** or **Phone Number and Country Code** any optional traits you know about them.
 
-Either of the two for user identification is required:
-
- - **user_id**
- - **phone_number** with **country_code**

+The `identify` call has the following fields:
+|Field|Data type|Description|
+|--|--|--|
+|user_id|str or int|The ID for the user in your database.|
+|country_code|str|country code for the phone_number (default value is "+91")|
+|phone_number|str|phone_number without country_code (eg: "9876598765")|
+|traits|dict|A dict of traits you know about the user. Things like: `email`, `name` or `age`|
 
-# Event
-`event` lets you record the actions your users perform. Every action triggers what we call an “event”, which can also have associated properties.
+**NOTE:** Atleast of these two is required for user identification :
+
+ - **user_id**, OR
+ - **phone_number** with **country_code**
+
+

+## Event
+`event` track API lets you record the actions your users perform. Every action triggers what we call an “event”, which can also have associated properties.
 
 Example `event` call:
 ```
 track.event(
-	user_id="<USER_ID>",
-	event="Add to Cart",
-	traits={"amount": 200}
+	user_id="changu_mangu",
+	event="Product Added",
+	traits={"price": 200}
 )
 ```
+The `event` call has the following fields:
+|Field|Data type|Description|
+|--|--|--|
+|user_id|str or int|The ID for the user in your database.|
+|event|str|Name of the event you want to track, For eg: "Product Added".|
+|traits|dict|dictionary of properties for the event. If the event was **Product Added**, it might have properties like `price` or `product_name`.|
