-As mentioned in the video above, you have to install `nodemon` to run the start script. You can install nodemon globally with `npm i -g nodemon` command.

 ### Send message to group
 
-I was added an example to send a message to groups, but before that we must know the group ID (chat ID). Don't worry, I also add the functionality to help you to get that groups ID.
+You can send the message to any group by using `chatID` or group `name`, chatID will used if you specify the `id` field in the form, so if you want to send by `name`, only use name.
+
+**Paramaters:**
+
+- `id` (optinal if name given): the chat ID
+- `name` (optional): group name
+- `message`: the message
+
+Here the endpoint: `/send-group-message`
 
 Here the way to get the groups info (including ID & name):
 
 - Send a message to the API number `!groups`
 - The API will replying with the groups info
 - Use the ID to send a message
-- Here the endpoint: `/send-group-message`
