# Introduction

> A self-hosted mini-PaaS for a single Linux VPS.

Source: https://quasar.achaverot.fr/docs/

Quasar turns a blank Linux VPS into a small hosting platform, with one command. You get:

- an admin dashboard on `admin.your-domain.com`,
- containerised applications, each on its own subdomain,
- automatic HTTPS for all of them.

New to it? Start with the [installation](/getting-started/installation/), then read the [concepts](/concepts/) — they are the words the rest of this documentation uses.

## When something breaks

The [troubleshooting page](/troubleshooting/) collects the usual failures and what causes them: a certificate that never arrives, a stack whose domain reaches nothing, a setting that seems to do nothing, a disk filling up.
