 ## Preliminary
 
 cid: chat_id

 mid: message_id
 
 ## Scenario
 
-1. A user sends us a message, named MSG-A
+1. A user sends us a message containing a task to be completed, referred to as MSG-A.
 
 2. We first reply to MSG-A with a progress updating message, named MSG-UPDATE. (Like "Processing your request...")
 
-3. Then we construct a special message (Named MSG-B) which can trigger the function of the third-party bot (bridgebot).
-   We log the chat_id (MSG-A's cid) and message_id (MSG-A's mid) to #ID tag in the MSG-B, format: #ID=(MSG-A's cid, MSG-A's mid)
-   And log the MSG-UPDATE tag in this format: #PROGRESS=(MSG-UPDATE's cid, MSG-UPDATE's mid) to MSG-B
-   More info can also be logged in MSG-B, like #URL, ...
+3. Then we construct a special message (named MSG-B) which can trigger the task of the third-party bot (bridgebot).
+
+   We log the `cid` and `mid` of MSG-A into MSG-B in this format: #ID=(MSG-A's cid,MSG-A's mid)
+
+   And log the `cid` and `mid` of MSG-UPDATE into MSG-B in this format: #PROGRESS=(MSG-UPDATE's cid,MSG-UPDATE's mid)

 4. Send MSG-B to bridgebot to finish the task.
 
 5. After the task is finished, the bridgebot will send us a new message containing the task results, named MSG-RES.
-So, we can retrieve the last message sent from us (MSG-B) to get the #ID tag and MSG-UPDATE tag, and then forward MSG-RES to MSG-A.

+   So, we can retrieve the last message sent from us (MSG-B) to parse the #ID (MSG-A) and #PROGRESS (MSG-UPDATE) info, and then forward MSG-RES to MSG-A.
 
 6. Finally, we delete MSG-UPDATE.
 
-For example, a user send us a douyin link which need to previewed. (MSG-A)
