| ## Introduction |
| |
| Pepper is an interface that web browsers (specifically, Chromium) provide for |
| implementing browser plugins. Pepper started out as an extension to Mozilla's |
| widely-used [NPAPI](http://en.wikipedia.org/wiki/NPAPI) interface, but Pepper v2 |
| provides a new API that is not an extension to NPAPI. |
| |
| [NaCl's integration with Chromium](chromium_integration.md) is implemented using |
| Pepper. However, NaCl also makes a Pepper-based interface available to web apps |
| over [IPC](imc_sockets.md). |
