Introduction
============

The Yocto Project team is happy for people to experiment with the Yocto
Project. There is a number of places where you can find help if you run into
difficulties or find bugs. This presents information about contributing
and participating in the Yocto Project.

.. _resources-contributions:

Contributions
=============

The Yocto Project gladly accepts contributions. You can submit changes
to the project either by creating and sending pull requests, or by
submitting patches through email. For information on how to do both as
well as information on how to identify the maintainer for each area of
code, see the ":ref:`dev-manual/common-tasks:submitting a change to the yocto project`" section in the
Yocto Project Development Tasks Manual.

.. _resources-bugtracker:

Yocto Project Bugzilla
======================

The Yocto Project uses its own implementation of
:yocto_bugs:`Bugzilla <>` to track defects (bugs).
Implementations of Bugzilla work well for group development because they
track bugs and code changes, can be used to communicate changes and
problems with developers, can be used to submit and review patches, and
can be used to manage quality assurance.

Sometimes it is helpful to submit, investigate, or track a bug against
the Yocto Project itself (e.g. when discovering an issue with some
component of the build system that acts contrary to the documentation or
your expectations).

For a general procedure and guidelines on how to use Bugzilla to submit a bug
against the Yocto Project, see the following:

-  The ":ref:`dev-manual/common-tasks:submitting a defect against the yocto project`"
   section in the Yocto Project Development Tasks Manual.

-  The Yocto Project :yocto_wiki:`Bugzilla wiki page </Bugzilla_Configuration_and_Bug_Tracking>`

For information on Bugzilla in general, see https://www.bugzilla.org/about/.

Links and Related Documentation
===============================

Here is a list of resources you might find helpful:

-  :yocto_home:`The Yocto Project Website <>`\ *:* The home site
   for the Yocto Project.

-  :yocto_wiki:`The Yocto Project Main Wiki Page <>`\ *:* The main wiki page for
   the Yocto Project. This page contains information about project
   planning, release engineering, QA & automation, a reference site map,
   and other resources related to the Yocto Project.

-  :oe_home:`OpenEmbedded <>`\ *:* The build system used by the
   Yocto Project. This project is the upstream, generic, embedded
   distribution from which the Yocto Project derives its build system
   (Poky) and to which it contributes.

-  :oe_wiki:`BitBake </BitBake>`\ *:* The tool used to process metadata.

-  :doc:`BitBake User Manual <bitbake:index>`\ *:* A comprehensive
   guide to the BitBake tool. If you want information on BitBake, see
   this manual.

-  :doc:`/brief-yoctoprojectqs/index` *:* This
   short document lets you experience building an image using the Yocto
   Project without having to understand any concepts or details.

-  :doc:`/overview-manual/index` *:* This manual provides overview
   and conceptual information about the Yocto Project.

-  :doc:`/dev-manual/index` *:* This manual is a "how-to" guide
   that presents procedures useful to both application and system
   developers who use the Yocto Project.

-  :doc:`/sdk-manual/index` *manual :* This
   guide provides information that lets you get going with the standard
   or extensible SDK. An SDK, with its cross-development toolchains,
   allows you to develop projects inside or outside of the Yocto Project
   environment.

-  :doc:`/bsp-guide/bsp` *:* This guide defines the structure
   for BSP components. Having a commonly understood structure encourages
   standardization.

-  :doc:`/kernel-dev/index` *:* This manual describes
   how to work with Linux Yocto kernels as well as provides a bit of
   conceptual information on the construction of the Yocto Linux kernel
   tree.

   Project manuals. It makes it easy to search for phrases and terms used
   in the Yocto Project documentation set.

-  :doc:`/profile-manual/index` *:* This manual presents a set of
   common and generally useful tracing and profiling schemes along with
   their applications (as appropriate) to each tool.
