+Cross compilation notes
+=======================
+
+Static 64 bit windows binary on Ubuntu 15.10 (Wily Werewolf)
+---------------------------------------------------------------------
+
+Install cross compiler and friends
+```sh
+sudo apt-get install g++-mingw-w64-x86-64
+```
+Default is to use Win32 threading model which lacks std::mutex and such. So we change defaults
+```sh
+sudo update-alternatives --set x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-posix
+```
+From now on we assume we have everything in `~/dev/`. Get Boost sources unpacked into `~/dev/boost_1_60_0/`
+and change directory to it.
+Now add out cross compiler configuration. Warning: the following will wipe out whatever you had in there.
+```sh
+echo "using gcc : mingw : x86_64-w64-mingw32-g++ ;" > ~/user-config.jam
+```
+Proceed with building Boost normal way, but let's define dedicated staging directory
+```sh
+./bootstrap.sh
+./b2 toolset=gcc-mingw target-os=windows variant=release link=static runtime-link=static address-model=64 \
+  --build-type=minimal --with-filesystem --with-program_options --with-regex --with-date_time \
+  --stagedir=stage-mingw-64
+cd ..
+```
+Now we get & build OpenSSL
+```sh
+git clone https://github.com/openssl/openssl
+cd openssl
+git checkout OpenSSL_1_0_2g
+./Configure mingw64 no-rc2 no-rc4 no-rc5 no-idea no-bf no-cast no-whirlpool no-md2 no-md4 no-ripemd no-mdc2 \
+  no-camellia no-seed no-comp no-krb5 no-gmp no-rfc3779 no-ec2m no-ssl2 no-jpake no-srp no-sctp no-srtp \
+  --prefix=~/dev/stage --cross-compile-prefix=x86_64-w64-mingw32-
+make depend
+make
+make install
+cd ..
+```
+and Zlib
+```sh
+git clone https://github.com/madler/zlib
+cd zlib
+git checkout v1.2.8
+CC=x86_64-w64-mingw32-gcc CFLAGS=-O3 ./configure --static --64 --prefix=~/dev/stage
+make
+make install
+cd ..
+```
+Now we prepare cross toolchain hint file for CMake, let's name it `~/dev/toolchain-mingw.cmake`
+```cmake
+SET(CMAKE_SYSTEM_NAME Windows)
+SET(CMAKE_C_COMPILER x86_64-w64-mingw32-gcc)
+SET(CMAKE_CXX_COMPILER x86_64-w64-mingw32-g++)
+SET(CMAKE_RC_COMPILER x86_64-w64-mingw32-windres)
+SET(CMAKE_FIND_ROOT_PATH /usr/x86_64-w64-mingw32)
+set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
+```
+Download miniupnpc, unpack, and symlink it into `~/dev/miniupnpc/`.
+Finally, we can build i2pd with all that goodness
+```sh
+git clone https://github.com/PurpleI2P/i2pd
+mkdir i2pd-mingw-64-build
+cd i2pd-mingw-64-build
+BOOST_ROOT=~/dev/boost_1_60_0 cmake -G 'Unix Makefiles' ~/dev/i2pd/build -DBUILD_TYPE=Release \
+  -DCMAKE_TOOLCHAIN_FILE=~/dev/toolchain-mingw.cmake -DWITH_AESNI=ON -DWITH_UPNP=ON -DWITH_STATIC=ON \
+  -DWITH_HARDENING=ON -DCMAKE_INSTALL_PREFIX:PATH=~/dev/i2pd-mingw-64-static \
+  -DZLIB_ROOT=~/dev/stage -DBOOST_LIBRARYDIR:PATH=~/dev/boost_1_60_0/stage-mingw-64/lib \
+  -DOPENSSL_ROOT_DIR:PATH=~/dev/stage
+make
+x86_64-w64-mingw32-strip i2pd.exe
+```
+By now, you should have a release build with stripped symbols.

 New family
 -----------
+
 You must create family self-signed certificate and key.  
 The only key type supposted is prime256v1.
-Use the following list of commands:
-openssl ecparam -name prime256v1 -genkey -out <your family name>.key
-openssl req -new -key <your family name>.key -out <your family name>.csr
-touch v3.ext
-openssl x509 -req -days 3650 -in <your family name>.csr -signkey <your family name>.key -out <your family name>.crt -extfile v3.ext
+Use the following list of commands:  
 
-specify <your family name>.family.i2p.net for CN.
+    openssl ecparam -name prime256v1 -genkey -out <your family name>.key

-Once you are done with it place <your family name>.key and <your family name>.crt to <ip2d data>/family folder (for exmple ~/.i2pd/family).
+Specify <your family name>.family.i2p.net for CN (Common Name) when requested.
+
+Once you are done with it place <your-family-name>.key and <your-family-name>.crt to <ip2d data>/family folder (for exmple ~/.i2pd/family).
 You should provide these two files to other members joining your family.
 If you want to register you family and let I2P network recorgnize it, create pull request for you .crt file into contrib/certificate/family.
-It will appear in i2pd and I2P next releases packages. Don't place .key file, it must be shared betwwen you family members only.

-Join existing family
---------------------
-Once you and that family agree to do it, they must give you .key and .crt file and you must place to <ip2d data>/family folder.
+How to join existing family
+---------------------------
+
+Once you and that family agree to do it, they must give you .key and .crt file and you must place in <i2pd datadir>/certificates/family/ folder.
 
 Publish your family
-------------------
-Run i2pd with parameter 'family=<your family name>', make sure you have <your family name>.key and <your family name>.crt in your 'family' folder.
-If everything is set properly, you router.info will contain two new fields: 'family' and 'family.sig'.
