<p>Many bundled components are developed by third-party contributors to the Langflow codebase.</p>
|
||
<p>Some providers contribute documentation with their bundles, whereas others document their bundles in their own documentation.
|
||
Some bundles have no documentation.</p>
|
||
<p>To find documentation for a specific bundled component, browse the Langflow docs and your provider's documentation.
|
||
If available, you can also find links to relevant documentation, such as API endpoints, through the component itself:</p>

|
||
<p>The Langflow documentation focuses on using bundles within flows.
|
||
For that reason, it focuses on the Langflow-specific configuration steps for bundled components.

For information about provider-specific features or APIs, see the provider's documentation.</p>

<p>Legacy components are longer supported and can be removed in a future release.

You can continue to use them in existing flows, but it is recommended that you replace them with supported components as soon as possible.

Suggested replacements are included in the <strong>Legacy</strong> banner on components in your flows.
|

They are also given in release notes and Langflow documentation whenever possible.</p>
