You can bring people into a project at any time, not only when you create it.
Each person gets either edit or view access, so you can share work without
giving everyone the ability to change it.
Before you start
You need access to the project.
You need permission to invite people to it.
Steps
Open the project.
Go to the project you want to add someone to.Start the invite.
Click Invite Team in the upper-right corner, or the + Add button.Find the person.
In the Invite Members window, search by their first name or their email
address.Choose their access.
Pick Can edit to let them make changes, or Can view to let them see
the project without changing anything.Send it.
Click Invite.
Notes / Tips
The person is added straight away with the access level you chose.
You can also see and manage members from the project's Overview tab, on
the right-hand side.Changing your mind later is fine — open the project and adjust their access.
Summary / Next Steps
Once someone has access, they see the project in their own list and can work on
it at the level you granted.
