 ## Requirements
 
-Building the API client library requires [Maven](https://maven.apache.org/) to be installed.
+Building the API client library requires:
+1. Java 1.7+
+2. Maven/Gradle
 
 ## Installation
 
 To install the API client library to your local Maven repository, simply execute:
 
 ```shell
-mvn install
+mvn clean install
 ```
 
 To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
 
 ```shell
-mvn deploy
+mvn clean deploy
 ```
 
-Refer to the [official documentation](https://maven.apache.org/plugins/maven-deploy-plugin/usage.html) for more information.
