+Redistribution and use in source and binary forms, with or without modification, are
+permitted provided that the following conditions are met:
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
+1. Redistributions of source code must retain the above copyright notice, this list of
+conditions and the following disclaimer.
 
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
+2. Redistributions in binary form must reproduce the above copyright notice, this list of
+conditions and the following disclaimer in the documentation and/or other materials
+provided with the distribution.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+3. Neither the name of the copyright holder nor the names of its contributors may be used
+to endorse or promote products derived from this software without specific prior written
+permission.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                            NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.

-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.

-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

+I2P router written in C++.
 
-Requirements for Linux/FreeBSD/OSX
-----------------------------------
+Documentation for config files, command line options, build instructions and more can be found under the doc directory.
 
-GCC 4.6 or newer, Boost 1.46 or newer, crypto++. Clang can be used instead of
-GCC.

-Requirements for Windows
-------------------------
+Official binary releases could be found at:
+http://download.i2p.io/purplei2p/i2pd/releases/
 
-VS2013 (known to work with 12.0.21005.1 or newer), Boost 1.46 or newer,

 Build Statuses
 ---------------
 
-- Linux x64      - [![Build Status](https://jenkins.nordcloud.no/buildStatus/icon?job=i2pd-linux)](https://jenkins.nordcloud.no/job/i2pd-linux/)
-- Linux ARM      - To be added

+- Linux x64      - Maintenance
+- Linux ARM      - Maintenance
+- Mac OS X       - Maintenance
 - Microsoft VC13 - To be added
-
-
-Testing
--------
-
-First, build it.
-
-* $ cd i2pd
-* $ make
-
-Next, find out your public ip. (find it for example at http://www.whatismyip.com/)
-
-Then, run it with:
-
-$ ./i2p --host=YOUR_PUBLIC_IP
-
-The client should now reseed by itself.
-
-To visit an I2P page, you need to find the b32 address of your destination.
-After that, go to the webconsole and add it behind the url. (Remove http:// from the address)
-
-This should resulting in for example:
-http://localhost:7070/4oes3rlgrpbkmzv4lqcfili23h3cvpwslqcfjlk6vvguxyggspwa.b32.i2p
-
-
-Options
--------
-
-* --host=               - The external IP
-* --port=               - The port to listen on
-* --httpport=           - The http port to listen on
-* --log=                - Enable or disable logging to file. 1 for yes, 0 for no.
-* --daemon=             - Enable or disable daemon mode. 1 for yes, 0 for no.
-* --service=            - 1 if uses system folders (/var/run/i2pd.pid, /var/log/i2pd.log, /var/lib/i2pd).
-* --unreachable=        - 1 if router is declared as unreachable and works through introducers.
-* --v6=                 - 1 if supports communication through ipv6, off by default
-* --httpproxyport=      - The port to listen on (HTTP Proxy)
-* --socksproxyport=     - The port to listen on (SOCKS Proxy)
-* --ircport=            - The local port of IRC tunnel to listen on. 6668 by default
-* --ircdest=            - I2P destination address of IRC server. For example irc.postman.i2p
-* --irckeys=            - optional keys file for local destination
-* --eepkeys=            - File name containing destination keys. For example privKeys.dat
-* --eephost=            - Address incoming trafic forward to. 127.0.0.1 by default
-* --eepport=            - Port incoming trafic forward to. 80 by default
-* --samport=            - Port of SAM bridge. Usually 7656. SAM is off if not specified

-Building i2pd for Windows
-=========================
-
-Requirements for building:
-
-* Visual Studio 2013 (tested with VS2013 Update 1, Update 3, and Update 4 RC)
-* Boost (tested with 1.56 and 1.57)
-* Crypto++ (tested with 5.6.2)
-
-
-Building Boost (32-bit)
------------------------
-
-Open a Visual Studio x86 command prompt and run the following:
-
-	cd C:\path\to\boost\sources
-	bootstrap
-	b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\Win32 install --with-filesystem --with-program_options --with-regex --with-date_time
-
-
-Building Boost (64-bit)
------------------------
-
-Open a Visual Studio x64 command prompt and run the following:
-
-	cd C:\path\to\boost\sources
-	bootstrap
-	b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\x64 architecture=x86 address-model=64 install --with-filesystem --with-program_options --with-regex --with-date_time
-
-After Boost is compiled, set the environment variable `BOOST` to the directory
-Boost was installed to. If you followed the instructions outlined here, you
-should set it to `C:\Boost`. Additionally, set the BOOSTVER variable to the
-version of Boost that you're using, but instead of a '.' use a '_'. For
-example, I have `BOOSTVER` set to `1_57`.
-
-Building Crypto++
------------------
-
-* Open the crypttest Solution in VS2013
-* Visual Studio will ask to update the Solution/Project. Allow it.
-* Build the `cryptopp` project, both the Debug and Release targets and for both
-  Win32 and x64.
-* Create a folder called `cryptopp` in the crypto++ source directory, then copy
-  the header files to this new directory.
-* Set the `CRYPTOPP` environment variable pointing to the Crypto++ source directory.
-
-
-Building i2pd
--------------
-
-## Prep work ##
-
-I strongly advise setting up your own `INCLUDES` and `LIBS` instead of relying
-on the settings in the i2pd project file. By using your own settings, if the
-i2pd devs change the paths in the project file, your builds will still work.
-
-To do this, create or edit the file
-`%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user`.
-
-For comparison, my file is reproduced below:
-
-	<?xml version="1.0" encoding="utf-8"?>
-	<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
-	  <ImportGroup Label="PropertySheets">
-	  </ImportGroup>
-	  <PropertyGroup Label="UserMacros" />
-	  <PropertyGroup>
-	    <LibraryPath>$(CRYPTOPP)\$(Platform)\Output\$(Configuration);$(BOOST)\lib\$(Platform);$(LibraryPath)</LibraryPath>
-	    <IncludePath>$(CRYPTOPP);$(BOOST)\include\boost-$(BOOSTVER);$(IncludePath)</IncludePath>
-	  </PropertyGroup>
-	  <ItemDefinitionGroup />
-	  <ItemGroup />
-	</Project>
-
-
-If you want to build x64 binaries as well, you'll want to edit or create the
-file `%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user`. If you
-followed the steps outlined earlier you can copy (or link) the win32 file to
-the x64 one.
-
-## Anti-Climatic End ##
-
-After following the above instructions, you'll be able to build Debug Win32,
-Debug x64, Release Win32, and Release x64 i2pd binaries.
