At the top is the [command line interface](../command-ref/command-ref.md), translating from invocations of Nix executables to interactions with the underlying layers.
Below that is the [Nix expression language](../expressions/expression-language.md), a [purely functional][purely-functional-programming] configuration language.
It is used to compose expressions which ultimately evaluate to self-contained *build plans*, made up *build tasks* used to derive *build results* from referenced *build inputs*.
