# flue update

Last updated Jul 17, 2026[View as Markdown](https://nightly.flueframework.com/docs/cli/update/index.md)

## Synopsis

```bash
flue update <kind> <name|url> [--print]
```

## Description

`flue update` fetches the Markdown implementation guide for a blueprint, for piping to a coding agent that will bring an existing integration up to the current blueprint version. The command does not inspect or modify your project — the guide carries the update instructions, including how to compare the existing integration against the current blueprint and preserve customizations.

[flue add](https://nightly.flueframework.com/docs/cli/add/) emits the same guide; the two commands differ only in intent and argument handling (`flue update` requires both arguments, while `flue add` alone lists the catalog). Output behavior matches `flue add`: the guide prints to stdout for coding agents or with `--print`.

## Arguments

| Argument    | Description                                                                                                              |
| ----------- | ------------------------------------------------------------------------------------------------------------------------ |
| <kind>      | The integration category: channel, database, sandbox, or tooling.                                                        |
| <name\|url> | A blueprint name matched within the kind, or an absolute URL to provider documentation for the build-from-scratch guide. |

## Options

| Option   | Description                                                                  |
| -------- | ---------------------------------------------------------------------------- |
| \--print | Write the blueprint Markdown to stdout regardless of coding-agent detection. |

## Examples

```bash
flue update channel slack --print | claude
flue update database mysql --print | codex

flue update channel https://developers.notion.com/reference/webhooks --print | claude
