# Local Development

Now we can build the project and try out network replication locally.

This example will show you how to launch a local [Replication Server](https://docs.coherence.io/1.0/coherence-sdk-for-unity/replication-server) and connect multiple instances.

### Running a Replication Server locally

You can run a local Replication Server from the *coherence* menu:

This will open a new terminal window with the Replication Server and a World created in it.

## Building through Coherence Hub

As with most features found in the menu, you can find local replication server functionality in the *Coherence Hub* as well. Open the *Servers* tab and run a Room or a World Replication Server.

### Build and Connect

Now it's time to make a standalone build and test network replication.

{% hint style="info" %}
\#protip: Go to *Project Settings, Player* and change the *Fullscreen Mode* to ***Windowed*** and enable ***Resizable Window***. This will make it much easier to observe standalone builds side-by-side when testing networking.
{% endhint %}

Open the *Build Settings* window (*File > Build Settings*). Click on *Add Open Scenes* to add the current scene to the build. Click *Build and Run***.**

Select a folder (e.g. *Builds*) and click *OK*.

When the build is done, start another instance of the executable (or run the project in the *Game Window* in Unity).

Click *Connect* on both clients. Now try focusing one and using WASD keys. You will see the box move on the other side as well.

Congratulations, you've made your first coherence replicated experience. But this is only the beginning. Keep reading to take advantage of more advanced coherence features.
