Deploy DocuSeal on Sliplane

2. Create a Service
- Open Projects (create a new project or use the default one).
- Click Deploy Service (top‑right).
- Select the DocuSeal preset (or use the official Docker image directly).
3. Deploy and Access
- Click Deploy and wait for the service to start.
- The domain will be shown in the service settings, e.g.
service-name.sliplane.app. - Open that URL and follow the on‑screen setup steps in the DocuSeal dashboard.
4. Initial Configuration
After the dashboard setup you’ll have a fully functional DocuSeal instance ready for use.
