 # Selfcare Onboarding
 
-Repository that contains backend services for selfcare onboarding.
+Repository that contains backend services for selfcare onboarding. It is a monorepo for onboarding domain that contains:
+
+- `onboarding-functions`: functions that handle all asynchronous activities related to preparing and completing the onboarding process. Indeed, they are activated by the onboarding microservice upon receiving an onboarding request
+- `onboarding-ms`: microservice that implements CRUD operations for the 'onboarding' object and the business logic for the onboarding phase. During the onboarding process
+- `onboarding-sdk`: Java utility classes that simplify the work of developers about onboarding activity
+
+Look at single README module for more information.

+# Onboarding SDK Azure Storage
+
+This library has been developed to provide a set of Java utility classes to simplify the work of interact with azure storage. It includes features that helping for upload or download file from an azure storage container.
+
+## Installation
+
+To use this library in your projects, you can add the dependency to your pom.xml if you're using Maven:
+
+```shell script
+<dependency>
+    <groupId>it.pagopa.selfcare</groupId>
+    <artifactId>onboarding-sdk-azure-storage</artifactId>
+    <version>0.0.1</version>
+</dependency>
+```
+
+If you are using Gradle, you can add the dependency to your build.gradle file:
+
+```shell script
+dependencies {
+    implementation 'it.pagopa.selfcare:onboarding-sdk-azure-storage:0.0.1'
+}
+```
+
+## Usage
+
+Here's an example of how to use AzureBlobClient:
+
+```java script
+
+public class Main {
+    public static void main(String[] args) {
+        final String azureStorageConnectionString = ... ; // set the azure storage connectionString, for ex.  AccountName=asd;AccountKey=asd;DefaultEndpointsProtocol=http;BlobEndpoint=http://127.0.0.1:10000/account;
+        final String azureStorageContainerName = ... ; // set the azure storage container name
+        final AzureBlobClient azureBlobClient = new AzureBlobClientDefault(azureStorageConnectionString, azureStorageContainerName);
+
+        //Getting file as text
+        final String filepath = ... ;
+        final String jsonString = azureBlobClient.getFileAsText(filepath);
+    }
+}
+```

+        final ProductService productService = new ProductServiceDefault(productJsonString);
+
+        //Get product if it is valid
+        final String productId = "prod-pagopa";
+        final Product product = productService.getProductIsValid(productId);
+    }
+}
