Clone your coin into debian's home folder using git:

git clone https://github.com/schyczewski/funcoin.git
(Obviously replace my info with yours)

Build base VM:

bin/make-base-vm --lxc --arch amd64 --suite precise

Dependencies (make sure this is done in the gitian-builder directory):

mkdir -p inputs; cd inputs/

wget 'http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.9.20140401.tar.gz' -O 'miniupnpc-1.9.20140401.tar.gz'

wget 'https://svn.boost.org/trac/boost/raw-attachment/ticket/7262/boost-mingw.patch' -O boost-mingw-gas-cross-compile-2013-03-03.patch

Building depencies (in gitian-builder, replace instances of 'funcoin' with whatever you named your clone):

./bin/gbuild ../funcoin/contrib/gitian-descriptors/boost-win32.yml
mv build/out/boost-*.zip inputs/

./bin/gbuild ../funcoin/contrib/gitian-descriptors/deps-win32.yml
mv build/out/bitcoin*.zip inputs/

./bin/gbuild ../funcoin/contrib/gitian-descriptors/qt-win32.yml
mv build/out/qt*.zip inputs/

Compile your coin (remember tag & name change):

./bin/gbuild --commit funcoin=v0.8 ../funcoin/contrib/gitian-descriptors/gitian-win32.yml
