| # Client libraries | |
| This directory contains client libraries for the Fuchsia SDK. These libraries | |
| are part of the Fuchsia API Surface. | |
| In most cases, these libraries are provided for the convenience of developers | |
| targeting Fuchsia. They typically are not part of the | |
| [system ABI](../../docs/concepts/packages/system.md). Instead, the system ABI is | |
| defined by the underlying [FIDL protocols](../fidl/). |
