+=========================================
+What I wish I'd known about Yocto Project
+=========================================
+
+|
+
+.. note::
+
+ Before reading further, make sure you've taken a look at the
+ :yocto_home:`Software Overview</software-overview>` page which presents the
+ definitions for many of the terms referenced here. Also, know that some of the
+ information here won't make sense now, but as you start developing, it is the
+ information you'll want to keep close at hand. These are best known methods for
+ working with Yocto Project and they are updated regularly.
+
+Using the Yocto Project is fairly easy, *until something goes wrong*. Without an
+understanding of how the build process works, you'll find yourself trying to
+troubleshoot "a black box". Here are a few items that new users wished they had
+known before embarking on their first build with Yocto Project. Feel free to
+contact us with other suggestions.
+
+#. **Use Git, not the tarball download:**
+ If you use git the software will be automatically updated with bug updates
+ because of how git works. If you download the tarball instead, you will need
+ to be responsible for your own updates.
+
+#. **Get to know the layer index:**
+ All layers can be found in the `layer index
+ <https://layers.openembedded.org/>`_. Layers which have applied for Yocto
+ Project Compatible status (structure continuity assurance and testing) can be
+ found in the :yocto_home:`Yocto Project Compatible index
+ </software-over/layer/>`. Generally check the Compatible layer index first,
+ and if you don't find the necessary layer check the general layer index. The
+ layer index is an original artifact from the Open Embedded Project. As such,
+ that index doesn't have the curating and testing that the Yocto Project
+ provides on Yocto Project Compatible layer list, but the latter has fewer
+ entries. Know that when you start searching in the layer index that not all
+ layers have the same level of maturity, validation, or usability. Nor do
+ searches prioritize displayed results. There is no easy way to help you
+ through the process of choosing the best layer to suit your needs.
+ Consequently, it is often trial and error, checking the mailing lists, or
+ working with other developers through collaboration rooms that can help you
+ make good choices.
+
+#. **Use existing BSP layers from silicon vendors when possible:**
+ Intel, TI, NXP and others have information on what BSP layers to use with
+ their silicon. These layers have names such as "meta-intel" or "meta-ti". Try
+ not to build layers from scratch. If you do have custom silicon, use one of
+ these layers as a guide or template and familiarize yourself with the
+ :doc:`bsp-guide/bsp-guide`.
+
+#. **Do not put everything into one layer:**
+ Use different layers to logically separate information in your build. As an
+ example, you could have a BSP layer, a GUI layer, a distro configuration,
+ middleware, or an application (e.g. "meta-filesystems", "meta-python",
+ "meta-intel", and so forth). Putting your entire build into one layer limits
+ and complicates future customization and reuse. Isolating information into
+ layers, on the other hand, helps keep simplify future customizations and
+ reuse.
+
+#. **Never modify the POKY layer. Never. Ever. When you update to the next
+ release, you'll lose all of your work. ALL OF IT.**
+
+#. **Don't be fooled by documentation searching results:**
+ Yocto Project documentation is always being updated. Unfortunately, when you
+ use Google to search for Yocto Project concepts or terms, Google consistently
+ searches and retrieves older versions of Yocto Project manuals. For example,
+ searching for a particular topic using Google could result in a "hit" on a
+ Yocto Project manual that is several releases old. To be sure that you are
+ using the most current Yocto Project documentation, use the drop-down menu at
+ the top of any of its page.
+
+ Many developers look through the :yocto_docs:`All-in-one 'Mega' Manual </singleindex.html>`
+ for a concept or term by doing a search through the whole page. This manual
+ is a concatenation of the core set of Yocto Project manual. Thus, a simple
+ string search using Ctrl-F in this manual produces all the "hits" for a
+ desired term or concept. Once you find the area in which you are
+ interested, you can display the actual manual, if desired. It is also
+ possible to use the search bar in the menu or in the left navigation pane.
+
+#. **Understand the basic concepts of how the build system works: the workflow:**
+ Understanding the Yocto Project workflow is important as it can help you both
+ pinpoint where trouble is occurring and how the build is breaking. The
+ workflow breaks down into the following steps:
+
+ #. Fetch – get the source code
+ #. Extract – unpack the sources
+ #. Patch – apply patches for bug fixes and new capability
+ #. Configure – set up your environment specifications
+ #. Build – compile and link
+ #. Install – copy files to target directories
+ #. Package – bundle files for installation
+
+ During "fetch", there may be an inability to find code. During "extract",
+ there is likely an invalid zip or something similar. In other words, the
+ function of a particular part of the workflow gives you an idea of what might
+ be going wrong.

+
+#. **Know that you can generate a dependency graph and learn how to do it:**
+ A dependency graph shows dependencies between recipes, tasks, and targets.
+ You can use the "-g" option with BitBake to generate this graph. When you
+ start a build and the build breaks, you could see packages you have no clue
+ about or have any idea why the build system has included them. The
+ dependency graph can clarify that confusion. You can learn more about
+ dependency graphs and how to generate them in the
+ :ref:`bitbake-user-manual/bitbake-user-manual-intro:generating dependency
+ graphs` section in the BitBake User Manual.
+
+#. **Here's how you decode "magic" folder names in tmp/work:**
+ The build system fetches, unpacks, preprocesses, and builds. If something
+ goes wrong, the build system reports to you directly the path to a folder
+ where the temporary (build/tmp) files and packages reside resulting from the
+ build. For a detailed example of this process, see the :yocto_wiki:`example
+ </Cookbook:Example:Adding_packages_to_your_OS_image>`. Unfortunately this
+ example is on an earlier release of Yocto Project.
+
+ When you perform a build, you can use the "-u" BitBake command-line option to
+ specify a user interface viewer into the dependency graph (e.g. knotty,
+ ncurses, or taskexp) that helps you understand the build dependencies better.
+
+#. **You can build more than just images:**
+ You can build and run a specific task for a specific package (including
+ devshell) or even a single recipe. When developers first start using the
+ Yocto Project, the instructions found in the
+ :doc:`brief-yoctoprojectqs/brief-yoctoprojectqs` show how to create an image
+ and then run or flash that image. However, you can actually build just a
+ single recipe. Thus, if some dependency or recipe isn't working, you can just
+ say "bitbake foo" where "foo" is the name for a specific recipe. As you
+ become more advanced using the Yocto Project, and if builds are failing, it
+ can be useful to make sure the fetch itself works as desired. Here are some
+ valuable links: :ref:`dev-manual/dev-manual-common-tasks:Using a Development
+ Shell` for information on how to build and run a specific task using
+ devshell. Also, the :ref:`SDK manual shows how to build out a specific recipe
+ <sdk-devtool-use-devtool-modify-to-modify-the-source-of-an-existing-component>`.
+
+#. **An ambiguous definition: Package vs Recipe:**
+ A recipe contains instructions the build system uses to create
+ packages. Recipes and Packages are the difference between the front end and
+ the result of the build process.
+
+ As mentioned, the build system takes the recipe and creates packages from the
+ recipe's instructions. The resulting packages are related to the one thing
+ the recipe is building but are different parts (packages) of the build
+ (i.e. the main package, the doc package, the debug symbols package, the
+ separate utilities package, and so forth). The build system splits out the
+ packages so that you don't need to install the packages you don't want or
+ need, which is advantageous because you are building for small devices when
+ developing for embedded and IoT.
+
+#. **You will want to learn about and know what's packaged in rootfs.**
+
+#. **Create your own image recipe:**
+ There are a number of ways to create your own image recipe. We suggest you
+ create your own image recipe as opposed to appending an existing recipe. It
+ is trivial and easy to write an image recipe. Again, do not try appending to
+ an existing image recipe. Create your own and do it right from the start.
+
+#. **Finally, here is a list of the basic skills you will need as a systems
+ developer. You must be able to:**
+
+ * deal with corporate proxies
+ * add a package to an image
+ * understand the difference between a recipe and package
+ * build a package by itself and why that's useful
+ * find out what packages are created by a recipe
+ * find out what files are in a package
+ * find out what files are in an image
+ * add an ssh server to an image (enable transferring of files to target)
+ * know the anatomy of a recipe
+ * know how to create and use layers
+ * find recipes (with the `OpenEmbedded Layer index <https://layers.openembedded.org>`_)
+ * understand difference between machine and distro settings
+ * find and use the right BSP (machine) for your hardware
+ * find examples of distro features and know where to set them
+ * understanding the task pipeline and executing individual tasks
+ * understand devtool and how it simplifies your workflow
+ * improve build speeds with shared downloads and shared state cache
+ * generate and understand a dependency graph
+ * generate and understand bitbake environment
+ * build an Extensible SDK for applications development
+
+#. **Depending on what you primary interests are with the Yocto Project, you
+ could consider any of the following reading:**
+
+ * **Look Through the Yocto Project Development Tasks Manual**: This manual
+ contains procedural information grouped to help you get set up, work with
+ layers, customize images, write new recipes, work with libraries, and use
+ QEMU. The information is task-based and spans the breadth of the Yocto
+ Project. See the :doc:`../dev-manual/dev-manual`.
+
+ * **Look Through the Yocto Project Application Development and the Extensible
+ Software Development Kit (eSDK) manual**: This manual describes how to use
+ both the standard SDK and the extensible SDK, which are used primarily for
+ application development. The :doc:`../sdk-manual/sdk-extensible` also provides
+ example workflows that use devtool. See the section
+ :ref:`sdk-manual/sdk-extensible:using \`\`devtool\`\` in your sdk workflow`
+ for more information.
+
+ * **Learn About Kernel Development**: If you want to see how to work with the
+ kernel and understand Yocto Linux kernels, see the :doc:`../kernel-dev/kernel-dev`.
+ This manual provides information on how to patch the kernel, modify kernel
+ recipes, and configure the kernel.
+
+ * **Learn About Board Support Packages (BSPs)**: If you want to learn about
+ BSPs, see the :doc:`../bsp-guide/bsp-guide`. This manual also provides an
+ example BSP creation workflow. See the :doc:`../bsp-guide/bsp` section.
+
+ * **Learn About Toaster**: Toaster is a web interface to the Yocto Project's
+ OpenEmbedded build system. If you are interested in using this type of
+ interface to create images, see the :doc:`../toaster-manual/toaster-manual`.
+
+ * **Have Available the Yocto Project Reference Manual**: Unlike the rest of
+ the Yocto Project manual set, this manual is comprised of material suited
+ for reference rather than procedures. You can get build details, a closer
+ look at how the pieces of the Yocto Project development environment work
+ together, information on various technical details, guidance on migrating
+ to a newer Yocto Project release, reference material on the directory
+ structure, classes, and tasks. The :doc:`../ref-manual/ref-manual` also
+ contains a fairly comprehensive glossary of variables used within the Yocto
+ Project.
