+Build notes
+===========
+
+Common build/install process:
+
+  git clone https://github.com/PrivacySolutions/i2pd.git
+  cd i2pd/build
+  cmake -DCMAKE_BUILD_TYPE=Release <more options> .
+  make
+  make install
+
+Available cmake options:
+
+* CMAKE_BUILD_TYPE -- build profile (Debug/Release)
+* WITH_AESNI -- AES-NI support (ON/OFF)
+* WITH_HARDENING -- enable hardening features (ON/OFF) (gcc only)
+
+Debian
+------
+
+Required "-dev" packages:
+
+* cmake
+* libboost-filesystem-dev
+* libboost-program-options-dev
+* libboost-regex-dev
+* libboost-system-dev
+* libcrypto++-dev
+
+FreeBSD
+-------
+
+Branch 9.X has gcc v4.2, that knows nothing about required c++11 standart.
+
+Required ports:
+
+* devel/cmake
+* devel/boost-libs
+* lang/gcc47 # or later version
+* security/cryptopp
+
+To use newer compiler you should set these variables:
+
+  export CC=/usr/local/bin/gcc47
+  export CXX=/usr/local/bin/g++47
+
+Replace "47" with your actual gcc version
+
+Branch 10.X has more reliable clang version, that can finally build i2pd,
+but i still recommend to use gcc, otherwise you will fight it's bugs by
+your own.
