# How to add more members? What is an invitation link? In Luffa, adding more members and using invitation links is very convenient, and you can easily migrate an existing group to Luffa. The specific steps are as follows: * **Add more members:** Enter the group details page, click "Add Member" in the member list, and choose your contacts to add them to the group. If the group requires approval for joining, the invited user must wait for the group owner's approval before officially joining the group. If no approval is needed, the invited user will join the group directly. * **Group invitation link:** In the group details page, find and copy the group link. Then, you can send this link to others to invite them to join the group. Any user with Luffa installed can click the link to directly join your group. Users who have not installed Luffa will be automatically redirected to the Luffa download page after clicking the invitation link, and after completing the download and installation, they can join the group. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
