title: Creating two dynamoDB tables in serverless.yml
body: <p>I'm try to add 2 tables to serverless.yml to link with DynamoDB. </p>
  
  <p>A part of my code in serverless.yml:</p>
  
  <pre><code>...       
   resources:
        Resources:
          ItemsTable:
            Type: "AWS::DynamoDB::Table"
            Properties:
              TableName: "InvoiceConfig"
              AttributeDefinitions:
              - AttributeName: "providerName"
                AttributeType: "S"
              KeySchema:
              - AttributeName: "providerName"
                KeyType: "HASH"
              ProvisionedThroughput:
                ReadCapacityUnits: 2
                WriteCapacityUnits: 2
              TableName: "DifferentTermsPages"
              AttributeDefinitions:
              - AttributeName: "id"
                AttributeType: "S"
              - AttributeName: "providerName"
                AttributeType: "S"
              - AttributeName: "productType"
                AttributeType: "S"
              - AttributeName: "language"
                AttributeType: "S"
              - AttributeName: "terms"
                AttributeType: "L"
              KeySchema:
              - AttributeName: "id"
                KeyType: "HASH"
              - AttributeName: "providerName"
                KeyType: "HASH"
              - AttributeName: "productType"
                KeyType: "HASH"
              - AttributeName: "language"
                KeyType: "HASH"
              - AttributeName: "terms"
                KeyType: "HASH"
              ProvisionedThroughput:
                ReadCapacityUnits: 10
                WriteCapacityUnits: 10
  </code></pre>
  
  <p>Is that correct??</p>
  
  <p>My tables are:</p>
  
  <pre><code>InvoiceConfig: with columns: providerName (String)
  DifferentTermsPages: id (String), providerName (String), productType (String), language (String), terms (list)
  </code></pre>
  
  <p>Do I need more changes in serverles.yml? what is the meaning of the expressions "ReadCapacityUnits" and "WriteCapacityUnits"?</p>
