# Finding LightAct Machines

To establish a LightNet cluster here are the steps you need to follow:

1. **Enable LightNet** on all machines
2. **Scan the network on Primary**: Primary should be able to find all LightAct machines on the network
3. **Assign LightNet roles**: this means you'll tell each machine in a cluster which role (Secondary, Backup or Editor) it will take.
4. **Establish cluster**: this means LightAct will run some Network checks, establish all the required communication channels, and transfer project files.
5. **Asset transfer**: Asset transfer is a separate step, that will be performed many times during a typical programming session.

So, let's proceed step by step.

## Enabling LightNet

In order to enable LightNet, just click on **Enabled checkbox** in **LightNet Management** window (available in Window top menu)

{% hint style="info" %}
**Good to know**: if you go to **Preferences**, **LightNet** tab you will find there a **Enable on new project** checkbox, which, if checked, ensures that everytime LightAct starts, LightNet is already enabled.

Alternatively, there is also a dedicated launch argument, that makes sure LightNet is enabled. Please refer to [Launching LightAct with Launch Arguments](/miscellaneous/launching-lightact-with-arguments.md).
{% endhint %}

## Scanning the Network

Click on **Scan network** button and all the machines in the cluster, that have LightNet enabled as well and use the same Multicast address and port, should appear.

Once they appear, it is time to Establish a cluster.
