| # Legacy components |
| |
| This section contains documentation about components using the legacy component |
| framework ([Components v1][glossary.components-v1]) implemented by `appmgr`. |
| The Fuchsia platform team is currently [migrating legacy components][migration] |
| to the modern component framework ([Components v2][glossary.components-v2]). |
| |
| Note: New component development should use the modern component framework. |
| For more details, see the [Components overview][components-overview]. |
