These guides provide instructions on how to install, maintain and upgrade Odoo databases.

## Installation

Depending on the intended use case, there are multiple ways to install Odoo - or not install it at
all.

- {doc}`Online <administration/odoo_online>` is the easiest way to use Odoo in production or to try it.
- {doc}`Packaged installers <administration/on_premise/packages>` are suitable for testing Odoo and
  developing modules. They can be used for long-term production with additional deployment and
  maintenance work.
- {doc}`Source install <administration/on_premise/source>` provides greater flexibility, as it
  allows, for example, running multiple Odoo versions on the same system. It is adequate to develop
  modules and can be used as a base for production deployment.
- A [Docker](https://hub.docker.com/_/odoo/) base image is available for development or
  deployment.

## Editions

There are two different editions.

**Odoo Community** is the free and open-source version of the software, licensed under the [GNU
LGPLv3](https://github.com/odoo/odoo/blob/master/LICENSE). It is the core upon which Odoo
Enterprise is built.

**Odoo Enterprise** is the shared source version of the software, giving access to more
functionalities, including functional support, upgrades, and hosting. [Pricing](https://www.odoo.com/pricing-plan) starts from one app free.
