# self-update.sh

> Move a bootstrapped kit tree to a newer signed kit version.

Source: `kit/self-update.sh` · audience: customer

## When you use this

Move an already-bootstrapped kit tree to a newer kit version, checked against the key recorded in the tree at bootstrap. `--check` reports what an update would do and changes nothing, which is the form to use before an upgrade window rather than during one.

## Usage

Emitted from the `usage()` block in `kit/self-update.sh`.
