 # Integrate KeyVault JCA provider with Jarsigner
 
-This is a simple guide to demonstrate how to integrate KeyVault JCA provider with Jarsigner.
+This guide provides a straightforward approach to integrating the KeyVault JCA provider with Jarsigner, ensuring a seamless process for users.
 
 ## Pre-requisites
-1. Prepare a certificate in Azure KeyVault.
-1. Prepare a service principal.
-1. Assign the principal with read and write permissoins of the KeyVault.
-2. Jarsigner supported Algorithms: ** DSA, RSA, ECDSA **.
+Before beginning, ensure you have the following:
 
-## Steps
+1. **Certificate in Azure KeyVault**: Prepare a certificate in Azure KeyVault.
+2. **Service Principal**: Create a service principal.
+3. **Permissions**: Assign the principal with read and write permissions for the KeyVault.
+4. **Jarsigner Supported Algorithms**: Ensure you are using one of the following supported algorithms: DSA, RSA, or ECDSA.
 
-1. Config JCA provider jar
-    1. Download azure-security-keyvault-jca from maven [repository](https://mvnrepository.com/artifact/com.azure/azure-security-keyvault-jca)
+## Step-by-Step Guide
+
+Follow these steps carefully to achieve successful integration:
+
+### Step 1: Configure JCA Provider Jar
+
+1. **Download the JCA Provider Jar**: Obtain the JCA provider jar file from the [official](https://mvnrepository.com/artifact/com.azure/azure-security-keyvault-jca) source.
+2. **Add to Java Environment**: 
     1. Place the jar under the folder `${JAVA_HOME}/jre/lib/ext`
         - ![Alt text](../Ressources/JCA/place_jar.png)
-    1. Open the file `java.security` in `${JAVA_HOME}/jre/lib/security`
-        - ![Alt text](../Ressources/JCA/java_security.png)
-    1. Edit the file `java.security` 
-        1. Add `security.provider.${Input_Your_Number}=com.azure.security.keyvault.jca.KeyVaultJcaProvider` as the picture shows.
-        1. ![Alt text](../Ressources/JCA/edit_provider.png)
-1. Sign with jarsigner
+
+### Step 2: Set Up Environment Variables
+
+Modify the `java.security` file in your Java installation to include the KeyVault JCA provider.
+
+1. Open the file `java.security` in `${JAVA_HOME}/jre/lib/security`
+   - ![Alt text](../Ressources/JCA/java_security.png)
+1. Edit the file `java.security`
+    1. Add `security.provider.${Input_Your_Number}=com.azure.security.keyvault.jca.KeyVaultJcaProvider` as the picture shows.
+    1. ![Alt text](../Ressources/JCA/edit_provider.png)
+
+### Step 3: Sign with Jarsigner
+
+1. **Prepare Your Jar**: Have the jar file you wish to sign ready.
+2. **Execute Jarsigner**: Use the Jarsigner tool with the KeyVault JCA provider to sign your jar file.
     1. Try to sign the jar using below command
-        ```bash
-        jarsigner   -keystore NONE -storetype AzureKeyVault \
-                    -signedjar signerjar.jar ${replace_with_your_jar.jar} ${replace_with_certificate} \
-                    -verbose  -storepass "" \
-                    -providerName AzureKeyVault \
-                    -providerClass com.azure.security.keyvault.jca.KeyVaultJcaProvider \
-                    -J-Dazure.keyvault.uri=${replace_with_your_kv_uri} \
-                    -J-Dazure.keyvault.tenant-id=${replace_with_your_sp_tenant-id} \
-                    -J-Dazure.keyvault.client-id=${replace_with_your_sp_client-id} \
-                    -J-Dazure.keyvault.client-secret=${replace_with_your_sp_client-secret} 
-        ```
+         ```bash
+         jarsigner   -keystore NONE -storetype AzureKeyVault \
+                     -signedjar signerjar.jar ${replace_with_your_jar.jar} ${replace_with_certificate} \
+                     -verbose  -storepass "" \
+                     -providerName AzureKeyVault \
+                     -providerClass com.azure.security.keyvault.jca.KeyVaultJcaProvider \
+                     -J-Dazure.keyvault.uri=${replace_with_your_kv_uri} \
+                     -J-Dazure.keyvault.tenant-id=${replace_with_your_sp_tenant-id} \
+                     -J-Dazure.keyvault.client-id=${replace_with_your_sp_client-id} \
+                     -J-Dazure.keyvault.client-secret=${replace_with_your_sp_client-secret} 
+         ```
     1. The output may look like this
