# Installation
### Cloud

Then ship it to your workspace:

See the app development guide for objects, views, agents, and logic functions.
Building with a coding agent? Install the official Twenty app skills, which work in Claude Code, Codex, Cursor, Pi, and any other harness supported by the `skills` CLI:
 [code] 
The `agent-skills` branch is created by the first successful publish from `main`. Until then, use the local build instructions. `SKILLS.md` explains the other skill families in this repository and who they are for.
### Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
