Afterwards you can create the *gdm85/gitian-bitcoin-host* image by running [scripts/create-gitian-bitcoin-host.sh](../scripts/create-gitian-bitcoin-host.sh).
[build-bitcoin.sh](bin/build-bitcoin.sh) is a script that will download & build all the dependencies and then bitcoin itself, for both i386 and amd64 Linux architectures.
In this example we will cover the former case; run [~/sign.sh](bin/sign.sh) script and check that your generated assert file (in a subdirectory of ~/gitian.sigs) matches with those of [other developers](https://github.com/bitcoin/gitian.sigs).
**NOTE:** Only the out_manifest signatures do matter, not all the dependencies.
If signatures do match, you can fork the [gitian sigs repo](https://github.com/bitcoin/gitian.sigs), add & commit your signatures and submit a pull request for inclusion.
