Gleam code is organized into units called modules. A module is a bunch of definitions (of types, functions, etc.) that seem to belong together. For example, the gleam/io module contains a variety of functions for printing, like println .

All gleam code is in some module or other, whose name comes from the name of the file it's in. For example, gleam/io is in a file called io.gleam in a directory called gleam.

For code in one module to access code in another module, we import it using the import keyword, and the name used to refer to it is the last part of the module name. For example, the gleam/io module is referred to as io once imported.

The as keyword can be used to refer to a module by a different name. See how the gleam/string module is referred to as text here.
