 | The Linux Kernel documentation | 
 | ============================== | 
 |  | 
 | This is the top level of the kernel's documentation tree.  Kernel | 
 | documentation, like the kernel itself, is very much a work in progress; | 
 | that is especially true as we work to integrate our many scattered | 
 | documents into a coherent whole.  Please note that improvements to the | 
 | documentation are welcome; join the linux-doc list at vger.kernel.org if | 
 | you want to help out. | 
 |  | 
 | Working with the development community | 
 | ====================================== | 
 |  | 
 | The essential guides for interacting with the kernel's development | 
 | community and getting your work upstream. |

 | Internal API manuals | 
 | ==================== |

 | kernel. |

 | Development tools and processes |

 | User-oriented documentation | 
 | =========================== | 
 |  | 
 | The following manuals are written for *users* of the kernel — those who are | 
 | trying to get it to work optimally on a given system and application | 
 | developers seeking information on the kernel's user-space APIs. | 
 |  | 
 | .. toctree:: | 
 |    :maxdepth: 1 | 
 |  | 
 |    Administration <admin-guide/index> | 
 |    Build system <kbuild/index> |

 |    Userspace tools <tools/index> | 
 |    Userspace API <userspace-api/index> | 
 |  | 
 | See also: the `Linux man pages <https://www.kernel.org/doc/man-pages/>`_, | 
 | which are kept separately from the kernel's own documentation. | 
 |  | 
 | Firmware-related documentation | 
 | ============================== | 
 | The following holds information on the kernel's expectations regarding the | 
 | platform firmwares. |

 | Other documentation | 
 | =================== | 
 |  | 
 | There are several unsorted documents that don't seem to fit on other parts | 
 | of the documentation body, or may require some adjustments and/or conversion | 
 | to reStructuredText format, or are simply too old. |
