+Development Version
+-------------------
+.. index:: Git
+
+RTEMS provides open access to it's development processes. The project encouages
+all users to inspect, review, comment and contribute to the code base. The
+processes described here are the same processes the core development team use
+when developing and maintaining RTEMS.
+
+.. warning::
+
+   The development version is not for use in production and it can break from
+   time to time.
+
+.. sidebar:: *GDB and Python*
+
+   RTEMS uses Python in GDB to aid debugging which means GDB needs to be built
+   with Python development libraries. Please check the RSB documentation and
+   install the packages specified for your host. Make sure a python development
+   package is included.
+
+The following procedure assumes you have installed and configured your host
+operating. It also assumes you have installed any dependent packages needed
+when building the tools and the kernel.
+
+You need to select a location to build and install the RTEMS Tool chain and
+RTEMS. Make sure there is plenty of disk space and a fast disk is
+recommended. Our procedure will document building and installing the tools in a
+home directory called :file:`development/rtems`. Using a home directory means
+you can do this without needing to be root. You can also use
+:file:`/opt/rtems/build` if you have access to that path.
+
+The location used to install the tools and kernel is called the `prefix`. It is
+best to have a `prefix` for each different version of RTEMS you are using. If
+you are using RTEMS 4.11 in production it is not a good to install a
+development version of 4.12 over the top. A separate `prefix` for each version
+avoids this.
+
+The RTEMS tool chain changes less often than the RTEMS kernel. One method of
+working with development releases is to have a separate `prefix` for the RTEMS
+tools and a different one for the RTEMS kernel. You can then update each
+without interacting with the other. You can also have a number of RTEMS
+versions available to test with.
+
+This procedure will build a SPARC tool chain.
+
+RTEMS Tools Chain
+~~~~~~~~~~~~~~~~~
+
+Clone the RTEMS Source Builder (RSB) repository:
+
+.. code-block:: shell
+
+  $ cd
+  $ mkdir -p development/rtems
+  $ cd development/rtems
+  $ git clone git://git.rtems.org/rtems-source-builder.git rsb
+  Cloning into 'rsb'...
+  remote: Counting objects: 5837, done.
+  remote: Compressing objects: 100% (2304/2304), done.
+  remote: Total 5837 (delta 4014), reused 5056 (delta 3494)
+  Receiving objects: 100% (5837/5837), 2.48 MiB | 292.00 KiB/s, done.
+  Resolving deltas: 100% (4014/4014), done.
+  Checking connectivity... done.
+
+.. sidebar:: *Downloading the source*
+
+  You need an internet connection to download the source. The downloaded source
+  is cached locally and the RSB checksums it. If you run a build again the
+  download output will be missing. Using the RSB from git will download the
+  source from the upstream project's home site and this could be `http`, `ftp`,
+  or `git`.
+
+Check all the host packages you need are present. Current libraries are not
+checked and this includes checking for the python development libraries GDB
+requires:
+
+.. code-block:: shell
+
+  $ cd rsb
+  $ ./source-builder/sb-check
+  RTEMS Source Builder - Check, 4.12 (e645642255cc)
+  Environment is ok
+
+Build a tool chain for the SPARC architecure. We are using the SPARC
+architecture because GDB has a good simulator that lets us run and test the
+samples RTEMS builds by default. The current development version
+is `4.12` and is on master:

+
+RTEMS Kernel
+~~~~~~~~~~~~
+
+We need to set our path to include the RTEMS tools we built in the previous
+section. The RTEMS tools needs to be first in your path because RTEMS provides
+specific versions of the ``autoconf`` and ``automake`` tools. We want to use
+the RTEMS version and not your host's versions:
+
+
+.. code-block:: shell
+
+  $ export PATH=$HOME/development/rtems/4.12/bin:$PATH
+
+Create a new location to build the RTEMS kernel:
+
+.. code-block:: shell
+
+  $ cd
+  $ cd development/rtems
+  $ mkdir kernel
+  $ cd kernel
+
+Clone the RTEMS respository:
+
+.. code-block:: shell
+
+  $ git clone git://git.rtems.org/rtems.git rtems
+  Cloning into 'rtems'...
+  remote: Counting objects: 483342, done.
+  remote: Compressing objects: 100% (88974/88974), done.

+  Resolving deltas: 100% (390053/390053), done.
+  Checking connectivity... done.
+
+The developers version of the code from git requires ``bootstrapping``. This is
+an ``autoconf`` and ``automake`` bootstrap to create the various files generated
+by ``autoconf`` and ``automake``. RTEMS does not keep these generated files
+under version control. The bootstrap process is slow so to speed it up the RSB
+provides a command that can perform the bootstrap in parallel using your
+available cores:
+
+.. code-block:: shell
+

+We build RTEMS in a directory outside of the source tree we have just cloned
+and ``bootstrapped``. You cannot build RTEMS while in the source tree. Lets
+create a suitable directory using the name of the BSP we are going to build:
+
+.. code-block:: shell
+
+  $ cd ..
+  $ mkdir erc32
+  $ cd erc32
+
+Configure RTEMS using the ``configure`` command. We use a full path to
+``configure`` so the object files built contain the absolute path of the source
+files. If you are source level debugging you will be able to access the source
+code to RTEMS from the debugger. We will build for the ``erc32`` BSP with POSIX
+enabled and the networking stack disabled:
+
+.. code-block:: shell

+All that remains to be done is to install the kernel. Installing RTEMS copies
+the API headers and architecture specific libraries to a locaiton under the
+`prefix` you provide. You can install any number of BSPs under the same
+`prefix`. We recommend you have a separate `prefix` for different versions of
+RTEMS. Do not mix versions of RTEMS under the same `prefix`. Make installs

+Contributing Patches
+~~~~~~~~~~~~~~~~~~~~
+
+RTEMS welcomes fixes to bugs and new features. The RTEMS Project likes to have
+bugs fixed against a ticket created on our :r:url:`devel`. Please raise a
+ticket if you have a bug. Any changes that are made can be tracked against the
+ticket. If you want to add a new a feature please post a message to
+:r:list:`devel` describing what you would like to implement. The RTEMS
+maintainer will help decide if the feature is in the best interest of the
+project. Not everything is and the maintainers need to evalulate how much
+effort it is to maintain the feature. Once accepted into the source tree it
+becomes the responsibility of the maintainers to keep the feature updated and
+working.
+
+Changes to the source tree are tracked using git. If you have not made changes
+and enter the source tree and enter a git status command you will see nothing
+has changed:
+
+.. code-block:: shell
+
+  $ cd ../rtems
+  $ git status
+  On branch master
+  Your branch is up-to-date with 'origin/master'.
+  nothing to commit, working directory clean
+
+We will make a change to the source code. In this example I change the help
+message to the RTEMS shell's ``halt`` command. Running the same git status
+command reports:
+
+.. code-block:: shell
+
+  $ git status
+  On branch master
+  Your branch is up-to-date with 'origin/master'.
+  Changes not staged for commit:
+    (use "git add <file>..." to update what will be committed)
+    (use "git checkout -- <file>..." to discard changes in working directory)
+
+          modified:   cpukit/libmisc/shell/main_halt.c
+
+  no changes added to commit (use "git add" and/or "git commit -a")
+
+As an example I have a ticket open and the ticket number is 9876. I commit the
+change with the follow git command:
+
+.. code-block:: shell
+
+  $ git commit cpukit/libmisc/shell/main_halt.c
+
+An editor is opened and I enter my commit message. The first line is a title
+and the following lines form a body. My message is:
+
+.. code-block:: shell
+
+  shell: Add more help detail to the halt command.
+
+  Closes #9876.
+
+  # Please enter the commit message for your changes. Lines starting
+  # with '#' will be ignored, and an empty message aborts the commit.
+  # Explicit paths specified without -i or -o; assuming --only paths...
+  #
+  # Committer: Chris Johns <chrisj@rtems.org>
+  #
+  # On branch master
+  # Your branch is up-to-date with 'origin/master'.
+  #
+  # Changes to be committed:
+  #       modified:   cpukit/libmisc/shell/main_halt.c
+
+When you save and exit the editor git will report the commit's status:
+
+.. code-block:: shell
+
+  $ git commit cpukit/libmisc/shell/main_halt.c
+  [master 9f44dc9] shell: Add more help detail to the halt command.
+   1 file changed, 1 insertion(+), 1 deletion(-)
+
+You can either email the patch to :r:list:`devel` with the following git
+command:
+
+.. code-block:: shell
+
+  $ git send-email --to=devel@rtems.org -1
+   <add output here>
+
+Or you can ask git to create a patch file using:
+
+.. code-block:: shell
+
+  $ git format-patch -1
+  0001-shell-Add-more-help-detail-to-the-halt-command.patch
+
+This patch can be attached to a ticket.
