# Use Case: Resources

{% hint style="success" %}
You should now see resource instances that were imported at start up, including a microdepot, three receivers, as well as two deliverers. If not, click [here](http://localhost:3000/#/organization/resources).
{% endhint %}

![Resource instances pre-defined in the scenario](https://2302517564-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LeJ6kGUyZS2zT96wHZ3%2F-MctNPlFiGHYcmKDPLnN%2F-MctRvgaJzG0IEphR1s-%2Fgrafik.png?alt=media\&token=5f6ce43f-35ea-43c6-8253-286aead28d67)

To explore the resource instances, click on a resource of the type _Receiver_. You will now see the different attributes of the resource, such as the street name, the wish-timeframe (wtf), and the city. Some attributes are not filled, as they are optional and not required in this use case.

We will now add another receiver, i.e., a parcel, to our scenario. For this, first copy the value of the _wtf_ attribute of the current instance (make sure to include the curly brackets):

```
{\"start\":\"2019-03-30T12:00:00.000Z\",\"end\":\"2019-03-30T14:00:00.000Z\"}
```

Now, click on **Create another Instance** on the right, and a form with all available attributes for the resource type _Receiver_ will be displayed. Paste the value to the _wtf_ field and fill in an address. The other attributes, _grossWeight_, _length_, and _width_ do not need to be filled. It is advisable to choose an address close to the other instances here as well, for example:

```
streetName:   August-Bebel-Straße
streetNumber: 46
zip:          14482
city:         Potsdam
```

{% hint style="info" %}
Please note that all adresses in this scenario exist but were drawn randomly and are in no way related to this project, its authors, institutions, etc.
{% endhint %}

![Adding another receiver to the scenario](https://2302517564-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LeJ6kGUyZS2zT96wHZ3%2F-MctV5Zh2e3Pf9IbU5IL%2F-MctVh5zz_weuSEFwQE6%2Fgrafik.png?alt=media\&token=b368ba94-42ee-4211-8fbf-78d8a0fcc202)

Now, click on **Create Resource** and you will be redirected again to the overview of resource instances.

{% hint style="success" %}
You should now again see the overview of currently configured resource instances, now showing four different instances for the type _Receiver_. If not, click [here](http://localhost:3000/#/organization/resources).
{% endhint %}

Of course, you can also further explore the other resource instances, or even add your own resource types and instances by following the steps in the [general user guide](../user-guide-1/resource-management). If you are ready, you can proceed to the next step.
