# Services

Services are the main unit of organization in the AssemblyLift framework. Primarily, they serve as a logical grouping of related [functions](/master/learn-assemblylift/functions.md).

## Make a New Service

You can create a new service in an existing AssemblyLift application via the `make` command:

```
$ asml make service myservice
```

This will create a directory under `services/` named `myservice` containing a default `service.toml` manifest.

In order for a service to be recognized by `cast`, it must be listed in the  application manifest `assemblylift.toml`.

{% code title="assemblylift.toml" %}

```
[project]
name = "my-amazing-project"
version = 0.0.0

[services]
default = { name = "myservice" }
```

{% endcode %}
