I completed this with this code , just read the arcticle well and that should be good enough . This is good for starting lightning .

<aura:component>
    <aura:attribute name=”item” type=”Camping_Item__c” required=”true”/>
    <p>
        Name: {!v.Item.Name}
    </p>
    <p>Quantity:
        <lightning:formattedNumber value=”{!v.Item.Quantity__c}” />
    </p>
    <p>Price:
        <lightning:formattedNumber value=”{!v.Item.Price__c}” style=”currency”/>
    </p>
    <p>
        Packed Status: {!v.item.Packed__c}
    </p>
    <p>
        <lightning:input type=”toggle” label=”Packed?” name=”Packed” checked=”{!v.Item.Packed__c}” />
    </p>
</aura:component>
