+Gitian building
+================
+
+*Setup instructions for a Gitian build of Monero using a VM or physical system.*
+
+Gitian is the deterministic build process that is used to build the Monero CLI
+executables. It provides a way to be reasonably sure that the
+executables are really built from the git source. It also makes sure that
+the same, tested dependencies are used and statically built into the executable.
+
+Multiple developers build the source code by following a specific descriptor
+("recipe"), cryptographically sign the result, and upload the resulting signature.
+These results are compared and only if they match, the build is accepted and provided
+for download.
+
+More independent Gitian builders are needed, which is why this guide exists.
+It is preferred you follow these steps yourself instead of using someone else's
+VM image to avoid 'contaminating' the build.
+
+Table of Contents
+------------------
+
+Please note that these instructions have been forked from bitcoin's gitian build
+instructions. Please also consult their documentation, when running into problems.
+The signing is left as inherited from bitcoin at the moment.
+

+- [Building Binaries](#building-bitcoin-core)
+- [Signing externally](#signing-externally)
+- [Uploading signatures](#uploading-signatures)
+
+Preparing the Gitian builder host
+---------------------------------
+
+The first step is to prepare the host environment that will be used to perform the Gitian builds.
+This guide explains how to set up the environment, and how to start the builds.
+
+Gitian builds are for now executed on Ubuntu 18.04 "Bionic Beaver". A solution is being worked on to run 
+it in docker in the future. Please run Ubuntu in either a VM, or on your physical machine.
+You need to be logged in as the `gitianuser` in order to build gitian builds. If this user does not exist yet on your system, 
+create it. 
+
+Note that a version of `lxc-execute` higher or equal to 2.1.1 is required.
+You can check the version with `lxc-execute --version`.
+
+First we need to set up dependencies. Type/paste the following in the terminal:
+
+```bash
+sudo apt-get install git ruby apt-cacher-ng qemu-utils debootstrap lxc python-cheetah parted kpartx bridge-utils make ubuntu-archive-keyring curl firewalld
+```
+
+Then set up LXC and the rest with the following, which is a complex jumble of settings and workarounds:
+
+```bash
+sudo -s
+# the version of lxc-start in Debian needs to run as root, so make sure
+# that the build script can execute it without providing a password
+echo "%sudo ALL=NOPASSWD: /usr/bin/lxc-start" > /etc/sudoers.d/gitian-lxc
+echo "%sudo ALL=NOPASSWD: /usr/bin/lxc-execute" >> /etc/sudoers.d/gitian-lxc
+# make /etc/rc.local script that sets up bridge between guest and host
+echo '#!/bin/sh -e' > /etc/rc.local
+echo 'brctl addbr br0' >> /etc/rc.local
+echo 'ip addr add 10.0.3.1/24 broadcast 10.0.3.255 dev br0' >> /etc/rc.local
+echo 'ip link set br0 up' >> /etc/rc.local
+echo 'firewall-cmd --zone=trusted --add-interface=br0' >> /etc/rc.local
+echo 'exit 0' >> /etc/rc.local
+chmod +x /etc/rc.local
+# make sure that USE_LXC is always set when logging in as gitianuser,
+# and configure LXC IP addresses
+echo 'export USE_LXC=1' >> /home/gitianuser/.profile
+echo 'export GITIAN_HOST_IP=10.0.3.1' >> /home/gitianuser/.profile
+echo 'export LXC_GUEST_IP=10.0.3.5' >> /home/gitianuser/.profile
+reboot
+```
+
+This setup is required to enable networking in the container.
+
+
+Manual and Building
+-------------------
+The instructions below use the automated script [gitian-build.py](https://github.com/betcoin/bitcoin/blob/master/contrib/gitian-build.py) which only works in Ubuntu. 
+It calls all available descriptors. Help for the build steps taken can be accessed with `./gitian-build.py --help`.
+
+Initial Gitian Setup
+--------------------
+The `gitian-build.py` script will checkout different release tags, so it's best to copy it:
+
+```bash
+cp monero/contrib/gitian/gitian-build.py .
+```
+
+Setup the required environment, you only need to do this once:
+
+```
+./gitian-build.py --setup fluffypony 0.14.0
+```
+
+Where `fluffypony` is your Github name and `0.14.0` is the version tag you want to build (without `v`).
+
+While gitian and this build script does provide a way for you to sign the build directly, it is recommended to sign in a seperate step. 
+This script is only there for convenience. Seperate steps for building can still be taken.
+In order to sign gitian builds on your host machine, which has your PGP key, 
+fork the gitian.sigs repository and clone it on your host machine, 
+or pass the signed assert file back to your build machine.
+
+```
+git clone git@github.com:monero-project/gitian.sigs.git
+git remote add fluffypony git@github.com:fluffypony/gitian.sigs.git
+```
+
+Build Binaries
+-----------------------------
+To build the most recent tag:
+
+ `./gitian-build.py --detach-sign --no-commit -b fluffypony 0.14.0`
+
+To speed up the build, use `-j 5 -m 5000` as the first arguments, where `5` is the number of CPU's you allocated to the VM plus one, and 5000 is a little bit less than then the MB's of RAM you allocated. If there is memory corruption on your machine, try to tweak these values.
+
+If all went well, this produces a number of (uncommited) `.assert` files in the gitian.sigs repository.
+
+If you do detached, offline signing, you need to copy these uncommited changes to your host machine, where you can sign them. For example:
+
+```
+export NAME=fluffypony
+export VERSION=0.14
+gpg --output $VERSION-linux/$NAME/monero-linux-$VERSION-build.assert.sig --detach-sign $VERSION-linux/$NAME/monero-linux-$VERSION-build.assert
+gpg --output $VERSION-osx-unsigned/$NAME/monero-osx-$VERSION-build.assert.sig --detach-sign $VERSION-osx-unsigned/$NAME/monero-osx-$VERSION-build.assert
+gpg --output $VERSION-win-unsigned/$NAME/monero-win-$VERSION-build.assert.sig --detach-sign $VERSION-win-unsigned/$NAME/monero-win-$VERSION-build.assert
+```
+
+Make a pull request (both the `.assert` and `.assert.sig` files) to the
+[monero-project/gitian.sigs](https://github.com/monero-project/gitian.sigs/) repository:
+
+```
+git checkout -b 0.14.0
+git commit -S -a -m "Add $NAME 0.14.0"
+git push --set-upstream $NAME 0.14.0
+```
+
+```bash
+    gpg --detach-sign ${VERSION}-linux/${SIGNER}/monero-linux-*-build.assert
+    gpg --detach-sign ${VERSION}-win-unsigned/${SIGNER}/monero-win-*-build.assert
+    gpg --detach-sign ${VERSION}-osx-unsigned/${SIGNER}/monero-osx-*-build.assert
+```
