# Welcome

Welcome to Portainer's official documentation site.

## About Portainer

Portainer hides the complexity of managing containers behind an easy-to-use UI. There's no need to touch the CLI, write YAML, or understand manifests - deploying apps and troubleshooting problems is simple enough for anyone to do.

It's a powerful toolset for building and managing containers across Kubernetes, Docker, Docker Swarm, Podman, and Azure ACI. Installing and using Portainer requires a license key - [request three nodes free](https://www.portainer.io/get-a-license) or [purchase a license](https://www.portainer.io/pricing).

Our team is here to help. Business customers get support through our [business support channels](#business-edition-customers), and free tier users can get help through our [community support channels](#five-three-node-free-home-and-student-and-starter-subscription-users).

## Documentation

{% hint style="info" %}
This documentation covers Portainer Business Edition (BE) only. Portainer Community Edition (CE) releases stopped at version 2.45 - for CE documentation, refer to [the 2.45 documentation](/start/install-ce.md).
{% endhint %}

We're working hard to ensure our documentation keeps up with Portainer's continued growth. If you have a question, we encourage you to start with the documentation. If you can't find what you're looking for, please raise a question in one of our support channels.

For more detailed step-by-step guides, we're expanding the [Portainer Academy](https://academy.portainer.io) and our [YouTube channel](https://www.youtube.com/@PortainerIO) with new courses regularly.

### Five/Three Node Free, Home & Student, and Starter subscription users

Five/Three Node Free, Home & Student, and Starter subscription users can get support through the following channels:

* **Ask our AI bot** from our [Ask the AI webpage](https://www.portainer.io/ask-the-ai). Our AI chatbot pulls from a number of sources and is a great place to start when looking for help.
* **Ask questions** either in our [GitHub Discussions](https://github.com/orgs/portainer/discussions/categories/help) forum or the [community Slack channel](https://portainer.io/slack). Other platforms exist (Reddit, Discord, Stack Overflow) but we are less active in those spaces.
* **Log bugs** in [GitHub Issues](https://github.com/portainer/portainer/issues) so they can be properly managed.
* **Report any security vulnerabilities** by emailing <security@portainer.io> or by [opening a vulnerability report in GitHub](https://github.com/portainer/portainer/security/advisories/new) so the issue can be reviewed and addressed as quickly as possible.
* **Flag documentation issues** via our [GitHub documentation channel](https://github.com/portainer/portainer-docs/issues) (or start [contributing](/3.0-sts/help/contribute.md) and make our documentation better!).
