# Glass > Glass is an open-source, Apple TV-style launcher for Fire TV and Android TV, with four ways to install it: the app, the app plus one adb command, a rooted install and a full system install. Runbooks are executable: an agent can follow them step by step against a connected stick, and every step has a verification command with expected output. Guides explain. When a guide and a runbook disagree, trust the runbook and tell the user. Anything marked "coming soon" is not built yet: do not attempt it. Every docs page is also available as raw Markdown by appending .md to its URL. ## Documentation Sets - [Abridged documentation](https://aazainkhan.github.io/glass-os/llms-small.txt): a compact version of the documentation for Glass, with non-essential content removed - [Complete documentation](https://aazainkhan.github.io/glass-os/llms-full.txt): the full documentation for Glass - [Runbooks](https://aazainkhan.github.io/glass-os/_llms-txt/runbooks.txt): step-by-step, verifiable procedures for an agent working on a connected stick - [Install guides](https://aazainkhan.github.io/glass-os/_llms-txt/install-guides.txt): human guides for each way to install Glass ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation
