# Tinka > A Go web framework: a small standard-library core and opt-in first-party packages that share one design language, built for agents to write and people to review. Every page below is also available as Markdown at its address plus `.md`. ## Start - [Introduction](https://tinka.tmuco.dev/start/introduction.md): What Tinka is, who it is for, and what exists in the alpha today. - [Philosophy](https://tinka.tmuco.dev/start/philosophy.md): The nine principles every part of Tinka follows, and why each one exists. - [Install the Tinka CLI](https://tinka.tmuco.dev/start/installation.md): Install the tinka command with go install and check that it works. ## Reference - [Agent mode output](https://tinka.tmuco.dev/reference/cli/agent-mode.md): How Tinka Commands answer when an AI agent runs them, with one JSON result per run. - [tinka version](https://tinka.tmuco.dev/reference/cli/version.md): Print the version of Tinka you are running, with the Go version and platform it was built for.
