((("Lightning node software", id="ix_04_node_client-asciidoc0", range="startofrange")))As we have seen in previous chapters, a Lightning node is a computer system that participates in the Lightning Network. The Lightning Network is not a product or company; it is a set of open standards that define a baseline for interoperability. As such, Lightning node software has been built by a variety of companies and community groups. The vast majority of Lightning software is _open source_, meaning that the source code is open and licensed in such a way as to enable collaboration, sharing, and community participation in the development process. Similarly, the Lightning node implementations we will present in this chapter are all open source and are collaboratively developed.
Unlike Bitcoin, where the standard is defined by a _reference implementation_ in software (Bitcoin Core), in ((("BOLT (Basis of Lightning Technology) standards documents")))Lightning the standard is defined by a series of standards documents called _Basis of Lightning Technology_ (_BOLT_), found at the https://github.com/lightningnetwork/lightning-rfc[_lightning-rfc_] repository.

There is no reference implementation of the Lightning Network, but there are several competing, BOLT-compliant, and interoperable implementations developed by different teams and organizations. The teams that develop software for the Lightning Network also contribute in the development and evolution of the BOLT standards.

Because the repository will be kept up-to-date as much as possible, you should always look for the latest version in the online repository instead of copying it from the printed book or the ebook.

This command allows us to specify an application composed of several containers and run the application by launching all the cooperating containers together.
First, let's install +docker-compose+. The https://docs.docker.com/compose/install/[instructions] depend on your operating system.
