 To enable the Azure Functions in eShop you can add the URI where the functions have been deployed. You can use the ARM files under **deploy/az/azurefunctions** to create the resources in Azure. Once created and available, it is necessary to add to the .env file the `ESHOP_AZUREFUNC_CAMPAIGN_DETAILS_URI` variable.
 
 For example:
- >ESHOP_AZUREFUNC_CAMPAIGN_DETAILS_URI=azurefunctionsuri

+# Deploying Azure Functions
+
+The ARM template `azurefunctionsdeploy.json` and its parameter file (`azurefunctionsdeploy.parameters.json`) are used to deploy Marketing azure functions.
+
+## Editing azurefunctionsdeploy.parameters.json file
+
+You can edit the `azurefunctionsdeploy.parameters.parameters.json` file to set your values, but is not needed. 
+
+## Deploy the template
+
+Once parameter file is edited you can deploy it using [create-resources script](../readme.md).
+
+i. e. if you are in windows, to deploy sql databases in a new resourcegroup located in westus, go to `deploy\az` folder and type:
+
+```
+create-resources.cmd azurefunctions\azurefunctionsdeploy newResourceGroup -c westus
+```
+## Deploy Marketing azure function with Visual Studio.
+
+Alternatively, instead of using ARM templates, you can deploy Marketing azure function directly by publishing the project Marketing-functions in eShopOnContainers-AzureFunctions.sln with Visual Studio publish tool.
+
+## Setting Azure function configurations
+
+Once deployed, go to azure portal and set the connection string for the azure function under the name "SqlConnection". The value must be the connection string which points to MarketingDB.
+
+Example:  
+
+"SqlConnection": "Server=tcp:eshopsql.database.windows.net,1433;Initial Catalog=marketingdb;"
+
+In appsettings section, add a new entry named "MarketingStorageUri". The value must be the uri of the blob storage where the campaign images are stored.
+
+Example:
+
+"MarketingStorageUri": "https://marketingcampaign.blob.core.windows.net/pics/"
+
