+Building twister

+***************************************************************
+*** THIS IS ALPHA SOFTWARE - THE BUILD SYSTEM IS UNFINISHED ***
+***************************************************************
+
+This software is a proof-of-concept, a forced marriage between
+bitcoin and libtorrent codebases. So don't expect an easy ride.
+Building this thing is quite hacky (but hopefully not complicated).
+
+In order to build twister you need to configure both bitcoin's and
+libtorrent's.
+
+1) Start with libtorrent:
+
+$ cd libtorrent
+$ ./configure --enable-logging --enable-debug --enable-dht
+
+Note1: 64-bit systems may need "--with-boost-libdir=/usr/lib64"
+Note2: disable logging if you want, but at this point it might
+       help to diagnose problems in case anything goes wrong.
+
+2) Then, for bitcoin/twister, you have actually two choices to
+build. Both will produce (almost) the same "twisterd" executable,
+so try which one works for you.
+
+2a) Using qmake
+
+$ qmake
+$ make
+
+2b) Using standard makefile
+
+$ cd src
+$ make -f makefile.unix
+
+
+DEPENDENCIES
+============
+
+OpenSSL, Berkeley DB, Boost and miniupnpc are required.
+
+Please read doc/build-unix.md for a complete list and instructions.
