3. Copy the chain of symbols and paste it into the manual connection box ("+" -> Enter key or link).
4. Click 'Next'.
Note: if you are using Sync 2.0 - 2.1, be sure to add btsync:// before the chain of symbols.
Headless computers
If this is a clean installation of Sync and you haven't yet created identity, you need to first create it and give it some name
Linux: ./rslsync --identity Name
Windows: "Resilio Sync.exe" /identity Name
Once the identity is created, apply the license file
Linux: ./rslsync --license /path/to/Sync_Home.btskey
Windows: "Resilio Sync.exe" /license C:\path\to\Sync.btskey
Share a License Seat
Once you've applied the multi-seat Business license key to an identity, share the remaining seats with others. On license Owner go to License menu and click to e-mail or copy the link and send it to other device.
- 'Copy' - this will copy license sharing link to clipboard. You can then manually paste the link into an e-mail, text file, message etc which will be sent to another person.
When a person receives the link, they need to paste it to "Manual Connection" field in Sync. License Owner will get request for accessing the seat:

By confirming approval, you will grant one of your seats to that person.
