# itch.io Publish (butler)

Get a build onto an itch.io page and keep it updated. The page is created in the browser; all
uploads go through **butler**, itch.io's command-line tool, with one command you'll use
forever: `butler push`. butler diffs against the previous build and uploads only what
changed. Deep CI/CD and flag detail lives in `references/butler-ci.md`.

## When to use

- Use when creating/updating an itch.io project page, installing or logging in to butler,
  uploading a build with `butler push`, choosing channel names, versioning uploads, or
  shipping a jam/demo/release build to itch.io.
- Triggers: `butler push`, `butler login`, channels, `.itch.toml`, "publish on itch",
  "upload to itch".
