+  <br>Sphereon's Azure KeyVault Key Management System REST Client Plugin
+  <br>
+</h1>
+
+## Overview
+
+This module provides a Key Management System (KMS) wrapper that enables the use of Azure Key Vault REST client functionalities within your application. It extends the capabilities of the `AbstractKeyManagementSystem` by integrating with Azure's robust key management features. This ensures that key generation, signing, and verification operations are handled securely and efficiently, aligning with Veramo's key management functions.
+
+## Available Functions
+
+- `createKey`
+- `sign`
+- `verify`
+
+## Installation
+
+To install the module, use the following command:
+
+```bash
+yarn add @sphereon/ssi-sdk-ext.kms-azure-rest-client
+```
+
+## Usage
+
+### Creating a Key
+
+To create a key, you need to specify the key type and optionally provide metadata, such as a key alias. Below is an example of how to create a key using the `AzureKeyVaultKeyManagementSystemRestClient`:
+
+```typescript
+import { AzureKeyVaultKeyManagementSystemRestClient } from '@sphereon/kms-azure-rest-client'
+
+const options = {
+  applicationId: 'azure-keyvault-test',
+  vaultUrl: 'https://example.vault.azure.net/',
+  apiKey: 'your-api-key-here',
+}
+
+const keyManagementSystem = new AzureKeyVaultKeyManagementSystemRestClient(options)
+
+async function createKeyExample() {
+  try {
+    const key = await keyManagementSystem.createKey({
+      type: 'Secp256r1',
+      meta: { keyAlias: 'my-secure-key' },
+    })
+
+    console.log('Key created:', key)
+  } catch (error) {
+    console.error('Error creating key:', error)
+  }
+}
+
+createKeyExample()
+```
+
+### Signing Data
+
+To sign data, provide the key reference (`kid`) and the data to be signed:
+
+```typescript
+async function signExample() {
+  try {
+    const signature = await keyManagementSystem.sign({
+      keyRef: { kid: 'your-key-id' },
+      data: new TextEncoder().encode('data-to-sign'),
+    })
+
+    console.log('Signature:', signature)
+  } catch (error) {
+    console.error('Error signing data:', error)
+  }
+}
+
+signExample()
+```
+
+### Verifying Data
+
+To verify data, provide the key reference (`kid`), the data, and the signature:
+
+```typescript
+async function verifyExample() {
+  try {
+    const isValid = await keyManagementSystem.verify({
+      keyRef: { kid: 'your-key-id' },
+      data: new TextEncoder().encode('data-to-verify'),
+      signature: 'signature-to-verify',
+    })
+
+    console.log('Is signature valid?', isValid)
+  } catch (error) {
+    console.error('Error verifying signature:', error)
+  }
+}
+
+verifyExample()
+```
+
+## Configuration
+
+The `AzureKeyVaultKeyManagementSystemRestClient` requires the following configuration options:
+
+- `applicationId`: A unique identifier for your application.
+- `vaultUrl`: The base URL of your Azure Key Vault.
+- `apiKey`: The API key for authenticating requests.
+
+## Limitations
+
+This implementation currently supports the following key operations:
+
+- `createKey`
+- `sign`
+- `verify`
+
+Additional functionalities like `sharedSecret`, `importKey`, `deleteKey`, and `listKeys` are not implemented in this version and will throw an error if called.
