+
+Note that the default Anonymous permissions are designed to not break existing
+server instances when upgrading, but are not particularly secure defaults. If
+you want to use authentication, it is recommended that you use "--anon-perms
+@read" to only give anonymous users read access, or "--anon-perms @none" to
+give un-authenticated users no access at all.
+
+Setting "--anon-perms @all" or "--anon-perms @user-admin" is not allowed, since
+this would allow anonymous users to manage all users accounts, which is a bad
+idea.
+
+If you are using user authentication, you should run your server in websockets
+mode with an SSL terminating load balancer in front of it (as this server does
+not implement SSL). Otherwise all usernames and passwords will be transmitted
+in the clear. When configured this way, clients can connect using a secure
+websocket, as in "wss://SERVER:PORT"
+
+The following permissions are supported by the server:
+
+    @none       - No permissions
+    @read       - The ability to read equivalent hashes from the server
+    @report     - The ability to report equivalent hashes to the server
+    @db-admin   - Manage the hash database(s). This includes cleaning the
+                  database, removing hashes, etc.
+    @user-admin - The ability to manage user accounts. This includes, creating
+                  users, deleting users, resetting login tokens, and assigning
+                  permissions.

+================
+Variable Context
+================
+
+|
+
+Variables might only have an impact or can be used in certain contexts. Some
+should only be used in global files like ``.conf``, while others are intended only
+for local files like ``.bb``. This chapter aims to describe some important variable
+contexts.
+
+.. _ref-varcontext-configuration:
+
+BitBake's own configuration
+===========================
+
+Variables starting with ``BB_`` usually configure the behaviour of BitBake itself.
+For example, one could configure:
+
+- System resources, like disk space to be used (:term:`BB_DISKMON_DIRS`),
+  or the number of tasks to be run in parallel by BitBake (:term:`BB_NUMBER_THREADS`).
+
+- How the fetchers shall behave, e.g., :term:`BB_FETCH_PREMIRRORONLY` is used
+  by BitBake to determine if BitBake's fetcher shall search only
+  :term:`PREMIRRORS` for files.
+
+Those variables are usually configured globally.
+
+BitBake configuration
+=====================
+
+There are variables:
+
+- Like :term:`B` or :term:`T`, that are used to specify directories used by
+  BitBake during the build of a particular recipe. Those variables are
+  specified in ``bitbake.conf``. Some, like :term:`B`, are quite often
+  overwritten in recipes.
+
+- Starting with ``FAKEROOT``, to configure how the ``fakeroot`` command is
+  handled. Those are usually set by ``bitbake.conf`` and might get adapted in a
+  ``bbclass``.
+
+- Detailing where BitBake will store and fetch information from, for
+  data reuse between build runs like :term:`CACHE`, :term:`DL_DIR` or
+  :term:`PERSISTENT_DIR`. Those are usually global.
+
+
+Layers and files
+================
+
+Variables starting with ``LAYER`` configure how BitBake handles layers.
+Additionally, variables starting with ``BB`` configure how layers and files are
+handled. For example:
+
+- :term:`LAYERDEPENDS` is used to configure on which layers a given layer
+  depends.
+
+- The configured layers are contained in :term:`BBLAYERS` and files in
+  :term:`BBFILES`.
+
+Those variables are often used in the files ``layer.conf`` and ``bblayers.conf``.
+
+Recipes and packages
+====================
+
+Variables handling recipes and packages can be split into:
+
+- :term:`PN`, :term:`PV` or :term:`PF` for example, contain information about
+  the name or revision of a recipe or package. Usually, the default set in
+  ``bitbake.conf`` is used, but those are from time to time overwritten in
+  recipes.
+
+- :term:`SUMMARY`, :term:`DESCRIPTION`, :term:`LICENSE` or :term:`HOMEPAGE`
+  contain the expected information and should be set specifically for every
+  recipe.
+
+- In recipes, variables are also used to control build and runtime
+  dependencies between recipes/packages with other recipes/packages. The
+  most common should be: :term:`PROVIDES`, :term:`RPROVIDES`, :term:`DEPENDS`,
+  and :term:`RDEPENDS`.
+
+- There are further variables starting with ``SRC`` that specify the sources in
+  a recipe like :term:`SRC_URI` or :term:`SRCDATE`. Those are also usually set
+  in recipes.
+
+- Which version or provider of a recipe should be given preference when
+  multiple recipes would provide the same item, is controlled by variables
+  starting with ``PREFERRED_``. Those are normally set in the configuration
+  files of a ``MACHINE`` or ``DISTRO``.

       ``ConfigParsed`` event can set the variable to trigger the re-parse.
       You must be careful to avoid recursive loops with this functionality.
 
+   :term:`BB_LOADFACTOR_MAX`
+      Setting this to a value will cause BitBake to check the system load
+      average before executing new tasks. If the load average is above the
+      the number of CPUs multipled by this factor, no new task will be started
+      unless there is no task executing. A value of "1.5" has been found to
+      work reasonably. This is helpful for systems which don't have pressure
