To add a colleague circle:
1. Download the Pulse app first and open it.
2. Start registering your account. And fill in your official position or occupation to ensure accuracy, because the software behind is generally about the personal relationship of your position.
3. After entering the pulse, upload the address book and you will get the distribution of contacts.
4. Search and add a colleague's pulse number. After the colleague agrees, you can join the colleague circle.
