# Authoring

ECS **Entities** can be found in the Scene, and as prefabs as regular GameObjects.

Add the **ConvertToNetworkEntity** component to them, so that Unity automatically converts them to Entities into either the Server scene, the Client scene, or both:

**Prefabs** need to be dragged into the PrefabSystem scene object’s registered Prefabs:

**Scene Objects** are converted automatically.

Right now, Unity has no Inspector for ECS **Systems**. They simply live in memory without us being able to modify their public variables. This is why **DOTSNET** has an authoring component for each system, like **NetworkServerAuthoring**:![](https://lh6.googleusercontent.com/WewZgDeXgqonS00ILNoY0p7Od_4CpvlbJ-O_RM7FH7L5h0s7JtMmLtKS-SNhKYwI7pZZck3VE2q2ih1f2nkllKgvfn8Z5R_SSka7nrLgTVp-YiEuWkQ6Y-5A3Q_1gJz5FX6gx8xX)

System Authoring components simply copy the exposed fields to the actual systems in the ECS world.

{% hint style="info" %}
Authoring likely won't be needed in the future as Unity adds better DOTS support.
