README-Cygwin.md

+### Installation on Windows
+To use telegram-cli in Windows, you should compile with Cygwin which has POSIX API functionality.
+
+Install [Cygwin](https://www.cygwin.com/) and cygwin's package manager, [apt-cyg](https://github.com/transcode-open/apt-cyg).
+
+In Cygwin Terminal, install compiler and tools :
+
+     apt-cyg install cygwin32-gcc-core cygwin32-gcc-g++ gcc-core gcc-g++ make wget patch diffutils grep tar gzip
+
+Now you have a compiler, but no libraries. You need readline, openssl, libconfig, liblua, python and libjansson to use telegram-cli's full functionality.
+
+
+Then Clone GitHub Repository in Cygwin Terminal
+
+     git clone --recursive https://github.com/vysheng/tg.git
+
+
+In Cygwin Terminal, type: 
+
+     apt-cyg install libevent-devel openssl-devel libreadline-devel lua-devel python3
+(Install package 'python' to use Python 2.7, or install package 'python3' to use Python 3)
+
+libconfig and libjansson is not in cygwin's package, so you should compile yourself.
+
+Compile libconfig
+     
+     wget http://www.hyperrealm.com/libconfig/libconfig-1.5.tar.gz
+     tar xvf libconfig-1.5.tar.gz && cd libconfig-1.5
+     ./configure
+     make && make install && cd ..
+
+Compile libjansson
+
+     wget http://www.digip.org/jansson/releases/jansson-2.7.tar.gz
+     tar xvf jansson-2.7.tar.gz && cd jansson-2.7
+     ./configure
+     make && make install && cd ..
+
+Then, go to tg directory then generate Makefile.
+
+     cd tg
+     ./configure
+     
+We need to patch Makefile and loop.c to compile in cygwin. Download this [patch](https://gist.github.com/ied206/d774a445f36004d263ab) then untar. Then, patch in tg directory.
+
+     patch -p1 < telegram-cli-cygwin.patch
+
+Then
+     make
+
+After compile is done, **telegram-cli.exe** will be generated in **bin** directory.
+
+To run telegram-cli, type
+     
+     bin/telegram-cli -k tg-server.pub
+
+**Caution**: A binary compiled with Cygwin should be run in Cygwin Terminal.
