# Getting started

Buy a license, install NexCMP, run the setup wizard, update and back up.

- [License and purchase](https://nexcmp.com/docs/getting-started/license-and-purchase/) — How NexCMP licensing works — getting a license key, binding it to a domain, reseller domains, update entitlement, and what happens when a license lapses.
- [Install NexCMP](https://nexcmp.com/docs/getting-started/installation/) — Install NexCMP on Ubuntu with the one-line installer — parameters, what the installer does, TLS and nginx, and how to reach the setup wizard.
