This is a quick guide about how to add Dropbox to your projects.
Copy the share URL for the folder or file you want to share.
Then, in your Project.co account go to the project you want to embed this tool into and click on "+ Add Tools" from the project dashboard. Then scroll to the 3rd Party Tools section and click on the Dropbox card. Paste the link you copied into the URL input.
Make sure the permissions are set correctly before you finish so that the right people can access the file/folder.
This creates a link tool that will open the Dropbox page in a new browser tab. This makes it quick and easy for people to get to this location from your project.
