+Next install the [Boost](http://www.boost.org) (1.73.0 - 1.76.0) development package. This can be accomplished via parameterization of the installation script during libbitcoin-system installation and it is recommended to the reader that this approach be used.
 
 Due to the current state of packaging, boost is not provided by the standard packaging system at the required minimum version. This requires either manual source compilation (as is controlled within the installation scripts) or trusting a 3rd party [Personal Package Archive](https://launchpad.net/ubuntu/+ppas). Verification of the build is done against the sources (required for proper use of ICU).
