+REQUIREMENTS:
+============
+
+* cmake (as build system)
+* OpenSSL
+* Pthreads (for POSIX systems it's builtin, for Windows there's a library)
+
+For Linux:
+==========
+
+Install cmake and openssl-devel (or similar name) package. For pthreads
+there should be -lpthreads linker flag added.
+
+## Ubunut 14
+```
+sudo apt-get update
+sudo apt-get upgrade
+sudo apt-get install tclsh pkg-config cmake libssl-dev build-essential
+./configure
+make
+```
+## CentOS 7
+```
+sudo yum update
+sudo yum install tcl pkgconfig openssl-devel cmake gcc gcc-c++ make automake
+./configure
+make
+```
+
+For Mac (Darwin, iOS):
+=====================
+
+Install cmake and openssl with development files from "brew". Note that the
+system version of OpenSSL is inappropriate, although you should be able to
+use any newer version compiled from sources, if you prefer.
+
+For Windows:
+============
+
+1. Install cmake for Windows. The CMake GUI will help you configure the project.
+Note that some variables must be provided explicitly. These are the default
+recommended values (required until some solution for running the `configure`
+script in Windows can be found):
+
+		WITH_OPENSSL_INCLUDEDIR=C:/OpenSSL-Win64/include
+		WITH_OPENSSL_LIBDIR=C:/OpenSSL-win64/lib/VC/static
+		WITH_OPENSSL_LIBRARIES=libeay32MT.lib ssleay32MT.lib
+		WITH_PTHREAD_INCLUDEDIR=C:/pthread-win32/include
+		WITH_PTHREAD_LDFLAGS=C:/pthread-win32/lib/pthread_lib.lib
+
+
+2. Please download and install OpenSSL for Windows.
+
+The 64-bit devel package can be downloaded from here:
+
+     http://slproweb.com/download/Win64OpenSSL-1_0_2a.exe
+
+It's expected to be installed in `C:\OpenSSL-Win64` (see the above variables).
+
+
+3. Compile and install Pthreads for Windows from this submodule:
+
+     submodules/pthread-win32
+
+Please follow the steps:
+
+a. Using Visual Studio 2013, please open this file:
+
+     pthread_lib.2013.vcxproj
+
+b. Make sure to select configuration: `Release` and `x64`.
+
+c. Make sure that the `pthread_lib` project will be built.
+
+d. After building, find the `pthread_lib.lib` file (directory is probably: `bin\x64_MSVC2013.Release`).
+Copy this file to `C:\pthread-win32\lib` (or whatever other location you configured in variables).
+
+e. Copy include files to `C:\pthread-win32\include` - the following ones:
+
+     pthread.h
+     sched.h
+     semaphore.h
+
+(They are in the toplevel directory, there are actually no meaningful subdirs here)
+(NOTE: the win32 is part of the project name. It will become 32 or 64 depending on selection)
