# Tier0 > Tier0 is an agentic industrial platform: a Unified Namespace (UNS) for real-time industrial data, flow-based data collection, an AI app builder, notebooks for analytics, and a launchpad for front-line users. Tier0 is built by FREEZONEX. The UNS organizes data semantically (site / area / equipment / process / order) over MQTT pub/sub. Interact with the platform via the web UI or the `tier0` CLI (npm: @tier0/cli, GitHub: FREEZONEX/Tier0-cli). Agent skills are available via `npx skills add FREEZONEX/Tier0-skill`. ## Documentation Sets - [Abridged documentation](https://docs.tier0.app/llms-small.txt): a compact version of the documentation for Tier0, with non-essential content removed - [Complete documentation](https://docs.tier0.app/llms-full.txt): the full documentation for Tier0 ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation ## Optional - [Tier0 website](https://tier0.app): Product overview, solutions, and pricing - [Tier0 CLI on GitHub](https://github.com/FREEZONEX/Tier0-cli): CLI source, install scripts, and issues - [Tier0-Edge on GitHub](https://github.com/FREEZONEX/Tier0-Edge): Open-source edge edition: source, README, install
