+Usage: $scriptName [-c|u|v|b|s|B|o|h|j|m|] signer version
+
+Run this script from the directory containing the bitcoin, gitian-builder, gitian.sigs, and bitcoin-detached-sigs.
+
+Arguments:
+signer          GPG signer to sign each build assert file
+version		Version number, commit, or branch to build. If building a commit or branch, the -c option must be specified
+
+Options:
+-c|--commit	Indicate that the version argument is for a commit or branch
+-u|--url	Specify the URL of the repository. Default is https://github.com/bitcoin/bitcoin
+-v|--verify 	Verify the gitian build
+-b|--build	Do a gitian build
+-s|--sign	Make signed binaries for Windows and Mac OSX
+-B|--buildsign	Build both signed and unsigned binaries
+-o|--os		Specify which Operating Systems the build is for. Default is lwx. l for linux, w for windows, x for osx
+-j		Number of processes to use. Default 2
+-m		Memory to allocate in MiB. Default 2000
+--kvm           Use KVM instead of LXC
+--setup         Setup the gitian building environment. Uses KVM. If you want to use lxc, use the --lxc option. Only works on Debian-based systems (Ubuntu, Debian)
+--detach-sign   Create the assert file for detached signing. Will not commit anything.
+--no-commit     Do not commit anything to git
+-h|--help	Print this help message

+### Verify Binaries
+
+#### Preparation:
+
+Make sure you obtain the proper release signing key and verify the fingerprint with several independent sources.
+
+```sh
+$ gpg --fingerprint "Bitcoin Core binary release signing key"
+pub   4096R/36C2E964 2015-06-24 [expires: 2017-02-13]
+      Key fingerprint = 01EA 5486 DE18 A882 D4C2  6845 90C8 019E 36C2 E964
+uid                  Wladimir J. van der Laan (Bitcoin Core binary release signing key) <laanwj@gmail.com>
+```
+
+#### Usage:
+
+This script attempts to download the signature file `SHA256SUMS.asc` from https://bitcoin.org.
+
+It first checks if the signature passes, and then downloads the files specified in the file, and checks if the hashes of these files match those that are specified in the signature file.
+
+The script returns 0 if everything passes the checks. It returns 1 if either the signature check or the hash check doesn't pass. If an error occurs the return value is 2.
+
+
+```sh
+./verify.sh bitcoin-core-0.11.2
+./verify.sh bitcoin-core-0.12.0
+./verify.sh bitcoin-core-0.13.0-rc3
+```
+
+If you do not want to keep the downloaded binaries, specify anything as the second parameter.
+
+```sh
+./verify.sh bitcoin-core-0.13.0 delete
+```
