+OpenOCD Documentation
+=====================
+
+In addition to the in-tree documentation, the latest manuals may be
+viewed online at the following URLs:
+
+ OpenOCD User's Guide:
+ http://openocd.org/doc/html/index.html
+
+ OpenOCD Developer's Manual:
+ http://openocd.org/doc/doxygen/html/index.html
+
+These reflect the latest development versions, so the following section
+introduces how to build the complete documentation from the package.
+
+For more information, refer to these documents or contact the developers

+
+Building the OpenOCD Documentation
+----------------------------------
+
+By default the OpenOCD build process prepares documentation in the
+"Info format" and installs it the standard way, so that "info openocd"
+can access it.
+
+Additionally, the OpenOCD User's Guide can be produced in the
+following different formats:
+
+ # If PDFVIEWER is set, this creates and views the PDF User Guide.
+ make pdf && ${PDFVIEWER} doc/openocd.pdf
+
+ # If HTMLVIEWER is set, this creates and views the HTML User Guide.
+ make html && ${HTMLVIEWER} doc/openocd.html/index.html
+
+The OpenOCD Developer Manual contains information about the internal
+architecture and other details about the code:
+
+ # NB! make sure doxygen is installed, type doxygen --version
+ make doxygen && ${HTMLVIEWER} doxygen/index.html

+Installing OpenOCD
+==================
+
+A Note to OpenOCD Users
+-----------------------
+
+If you would rather be working "with" OpenOCD rather than "on" it, your
+operating system or JTAG interface supplier may provide binaries for
+you in a convenient-enough package.
+
+Such packages may be more stable than git mainline, where
+bleeding-edge development takes place. These "Packagers" produce
+binary releases of OpenOCD after the developers produces new "release"
+versions of the source code. Previous versions of OpenOCD cannot be
+used to diagnose problems with the current release, so users are
+encouraged to keep in contact with their distribution package
+maintainers or interface vendors to ensure suitable upgrades appear
+regularly.
+
+Users of these binary versions of OpenOCD must contact their Packager to
+ask for support or newer versions of the binaries; the OpenOCD
+developers do not support packages directly.
+
+A Note to OpenOCD Packagers
+---------------------------
+
+You are a PACKAGER of OpenOCD if you:
+
+- Sell dongles and include pre-built binaries;
+- Supply tools or IDEs (a development solution integrating OpenOCD);
+- Build packages (e.g. RPM or DEB files for a GNU/Linux distribution).
+
+As a PACKAGER, you will experience first reports of most issues.
+When you fix those problems for your users, your solution may help
+prevent hundreds (if not thousands) of other questions from other users.
+
+If something does not work for you, please work to inform the OpenOCD
+developers know how to improve the system or documentation to avoid
+future problems, and follow-up to help us ensure the issue will be fully
+resolved in our future releases.
+
+That said, the OpenOCD developers would also like you to follow a few
+suggestions:
+
+- Send patches, including config files, upstream, participate in the
+ discussions;
+- Enable all the options OpenOCD supports, even those unrelated to your
+ particular hardware;
+- Use "ftdi" interface adapter driver for the FTDI-based devices.
+
+
+================
+Building OpenOCD
+================
+
+The INSTALL file contains generic instructions for running 'configure'
+and compiling the OpenOCD source code. That file is provided by
+default for all GNU autotools packages. If you are not familiar with
+the GNU autotools, then you should read those instructions first.
+
+The remainder of this document tries to provide some instructions for
+those looking for a quick-install.
+
+OpenOCD Dependencies
+--------------------
+
+GCC or Clang is currently required to build OpenOCD. The developers
+have begun to enforce strict code warnings (-Wall, -Werror, -Wextra,
+and more) and use C99-specific features: inline functions, named
+initializers, mixing declarations with code, and other tricks. While
+it may be possible to use other compilers, they must be somewhat
+modern and could require extending support to conditionally remove
+GCC-specific extensions.
+
+You'll also need:
+
+- make
+- libtool
+- pkg-config >= 0.23 (or compatible)
+
+Additionally, for building from git:
+
+- autoconf >= 2.64
+- automake >= 1.14
+- texinfo
+
+USB-based adapters depend on libusb-1.0 and some older drivers require
+libusb-0.1 or libusb-compat-0.1. A compatible implementation, such as
+FreeBSD's, additionally needs the corresponding .pc files.
+
+USB-Blaster, ASIX Presto and OpenJTAG interface adapter
+drivers need:
+ - libftdi: http://www.intra2net.com/en/developer/libftdi/index.php
+
+CMSIS-DAP support needs HIDAPI library.
+
+Permissions delegation
+----------------------
+
+Running OpenOCD with root/administrative permissions is strongly
+discouraged for security reasons.
+
+For USB devices on GNU/Linux you should use the contrib/60-openocd.rules
+file. It probably belongs somewhere in /etc/udev/rules.d, but
+consult your operating system documentation to be sure. Do not forget
+to add yourself to the "plugdev" group.
+
+For parallel port adapters on GNU/Linux and FreeBSD please change your
+"ppdev" (parport* or ppi*) device node permissions accordingly.
+
+For parport adapters on Windows you need to run install_giveio.bat
+(it's also possible to use "ioperm" with Cygwin instead) to give
+ordinary users permissions for accessing the "LPT" registers directly.
+
+Compiling OpenOCD
+-----------------
+
+To build OpenOCD, use the following sequence of commands:
+
+ ./bootstrap (when building from the git repository)
+ ./configure [options]
+ make
+ sudo make install
+
+The 'configure' step generates the Makefiles required to build
+OpenOCD, usually with one or more options provided to it. The first
+'make' step will build OpenOCD and place the final executable in
+'./src/'. The final (optional) step, ``make install'', places all of
+the files in the required location.
+
+To see the list of all the supported options, run
+ ./configure --help
+
+Cross-compiling Options
+-----------------------
+
+Cross-compiling is supported the standard autotools way, you just need
+to specify the cross-compiling target triplet in the --host option,
+e.g. for cross-building for Windows 32-bit with MinGW on Debian:
+
+ ./configure --host=i686-w64-mingw32 [options]
+
+To make pkg-config work nicely for cross-compiling, you might need an
+additional wrapper script as described at
+
+ http://www.flameeyes.eu/autotools-mythbuster/pkgconfig/cross-compiling.html
+
+This is needed to tell pkg-config where to look for the target
+libraries that OpenOCD depends on. Alternatively, you can specify
+*_CFLAGS and *_LIBS environment variables directly, see "./configure
+--help" for the details.
+
+Parallel Port Dongles
+---------------------
+
+If you want to access the parallel port using the PPDEV interface you
+have to specify both --enable-parport AND --enable-parport-ppdev, since the
+the later option is an option to the parport driver.
+
+The same is true for the --enable-parport-giveio option, you have to
+use both the --enable-parport AND the --enable-parport-giveio option
+if you want to use giveio instead of ioperm parallel port access
+method.
+
+
+==========================
+Obtaining OpenOCD From GIT
+==========================
+
+You can download the current GIT version with a GIT client of your
+choice from the main repository:
+
+ git://git.code.sf.net/p/openocd/code
+
+You may prefer to use a mirror:
+
+ http://repo.or.cz/r/openocd.git
+ git://repo.or.cz/openocd.git
+
+Using the GIT command line client, you might use the following command
+to set up a local copy of the current repository (make sure there is no
+directory called "openocd" in the current directory):
+
+ git clone git://git.code.sf.net/p/openocd/code openocd
+
+Then you can update that at your convenience using
+
+ git pull
+
+There is also a gitweb interface, which you can use either to browse
+the repository or to download arbitrary snapshots using HTTP:
+
+ http://repo.or.cz/w/openocd.git
+
+Snapshots are compressed tarballs of the source tree, about 1.3 MBytes
+each at this writing.
