 i2pd
 ====
 
-I2P router written in C++
+[Русская версия](https://github.com/PurpleI2P/i2pd_docs_ru/blob/master/README.md)
+
+i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.  
+
+I2P (Invisible Internet Protocol) is a universal anonymous network layer.  
+All communications over I2P are anonymous and end-to-end encrypted, participants
+don't reveal their real IP addresses.  
+
+I2P client is a software used for building and using anonymous I2P
+networks. Such networks are commonly used for anonymous peer-to-peer
+applications (filesharing, cryptocurrencies) and anonymous client-server
+applications (websites, instant messengers, chat-servers).  
+
+I2P allows people from all around the world to communicate and share information
+without restrictions.  
+
+Features
+--------
+
+* Distributed anonymous networking framework  
+* End-to-end encrypted communications  
+* Small footprint, simple dependencies, fast performance  
+* Rich set of APIs for developers of secure applications  
+
+Resources
+---------
+
+* [Website](http://i2pd.website)
+* [Documentation](https://i2pd.readthedocs.io/en/latest/)
+* [Wiki](https://github.com/PurpleI2P/i2pd/wiki)
+* [Tickets/Issues](https://github.com/PurpleI2P/i2pd/issues)
+* [Specifications](https://geti2p.net/spec)
+* [Twitter](https://twitter.com/hashtag/i2pd)
+
+Installing
+----------
+
+The easiest way to install i2pd is by using precompiled packages and binaries.
+You can fetch most of them on [release](https://github.com/PurpleI2P/i2pd/releases/latest) page.  
+Please see [documentation](https://i2pd.readthedocs.io/en/latest/user-guide/install/) for more info.
+
+Building
+--------
+See [documentation](https://i2pd.readthedocs.io/en/latest/) for how to build
+i2pd from source on your OS.  
+
+note: i2pd with Qt GUI can be found in [i2pd-qt](https://github.com/PurpleI2P/i2pd-qt) repository and for android in [i2pd-android](https://github.com/PurpleI2P/i2pd-android) repository.

+Using i2pd
+----------
+
+See [documentation](https://i2pd.readthedocs.io/en/latest/user-guide/run/) and
+[example config file](https://github.com/PurpleI2P/i2pd/blob/openssl/contrib/i2pd.conf).
+
+Localization
+------------
+
+You can help us with translation i2pd to your language using Crowdin platform!
+Translation project can be found [here](https://crowdin.com/project/i2pd).
+
+New languages can be requested on project's [discussion page](https://crowdin.com/project/i2pd/discussions).

-Requirements for Linux/FreeBSD/OSX
-----------------------------------
-
-GCC 4.6 or newer, Boost 1.46 or newer, crypto++. Clang can be used instead of
-GCC.
-
-Requirements for Windows
-------------------------
-
-VS2013 (known to work with 12.0.21005.1 or newer), Boost 1.46 or newer,
-crypto++ 5.62. See Win32/README-Build.txt for instructions on how to build i2pd
-and its dependencies.
-
-Downloads
-------------
-
-Official binary releases could be found at:
-http://download.i2p.io/purplei2p/i2pd/releases/

-
-Build Statuses
----------------
-
-- Linux x64      - [![Build Status](https://jenkins.greyhat.no/buildStatus/icon?job=i2pd-linux)](https://jenkins.nordcloud.no/job/i2pd-linux/)
-- Linux ARM      - To be added
-- Mac OS X       - Got it working, but not well tested. (Only works with clang, not GCC.)
-- Microsoft VC13 - To be added
-
-
-Testing
--------
-
-First, build it.
-
-On Ubuntu/Debian based
-* sudo apt-get install libboost-dev libboost-filesystem-dev libboost-program-options-dev libboost-regex-dev libcrypto++-dev libboost-date-time-dev
-* $ cd i2pd
-* $ make
-
-Then, run it:
-
-$ ./i2p
-
-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
-
-
-Cmdline options
----------------
-
-* --host=               - The external IP (deprecated). 
-* --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).
-* --v6=                 - 1 if supports communication through ipv6, off by default
-* --floodfill=          - 1 if router is floodfill, off by default
-* --bandwidth=          - L if bandwidth is limited to 32Kbs/sec, O if not. Always O if floodfill, otherwise L by default.
-* --httpproxyport=      - The port to listen on (HTTP Proxy)
-* --socksproxyport=     - The port to listen on (SOCKS Proxy)
-* --proxykeys=          - optional keys file for proxy's local destination
-* --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 tunnel's local destination 
-* --eepkeys=            - File name containing destination keys, for example privKeys.dat.
-                          The file will be created if it does not already exist (issue #110).
-* --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
-* --bobport=            - Port of BOB command channel. Usually 2827. BOB is off if not specified
-* --i2pcontrolport=     - Port of I2P control service. Usually 7650. I2PControl is off if not specified
-* --conf=               - Config file (default: ~/.i2pd/i2p.conf or /var/lib/i2pd/i2p.conf)
-                          This parameter will be silently ignored if the specified config file does not exist.
-                          Options specified on the command line take precedence over those in the config file.
-
-Config files
-------------
-
-INI-like, syntax is the following : <key> = <value>.
-All command-line parameters are allowed as keys, for example:
-
-i2p.conf:
-
-	log = 1
-	v6 = 0
-	ircdest = irc.postman.i2p
-
-tunnels.cfg (filename of this config is subject of change):
-
-  ; outgoing tunnel sample, to remote service   
-  ; mandatory parameters:   
-  ; * type -- always "client"  
-  ; * port -- local port to listen to   
-  ; * destination -- i2p hostname   
-  ; optional parameters (may be omitted)   
-  ; * keys -- our identity, if unset, will be generated on every startup,   
-  ;     if set and file missing, keys will be generated and placed to this file   
-	[IRC]   
-	type = client   
-	port = 6668   
-	destination = irc.echelon.i2p   
-	keys = irc-keys.dat   
-   
-  ; incoming tunnel sample, for local service   
-  ; mandatory parameters:   
-  ; * type -- always "server"   
-  ; * host -- ip address of our service   
-  ; * port -- port of our service   
-  ; * keys -- file with LeaseSet of address in i2p   
-  ; optional parameters (may be omitted)   
-  ; * inport -- optional, i2p service port, if unset - the same as 'port'   
-  ; * accesslist -- comma-separated list of i2p addresses, allowed to connect   
-  ;    every address is b32 without '.b32.i2p' part   
-	[LOCALSITE]   
-	type = server   
-	host = 127.0.0.1   
-	port = 80   
-	keys = site-keys.dat   
-	inport = 81
