-This is a small wrapper for the OVH API in Java. It aims to provide tools to handle the most off-putting part of using this API.
+This is a small wrapper for the OVH API in Java. It aims to provide tools to handle the most off-putting part of using this API.
+
+## Installation
+
+If you have a Maven installation, navigate to the folder in which you cloned the repo, and type :
+ 
+```bash
+mvn package
+```
+
+to compile and package the sources into a JAR file (usual output directory is 'target'). To install the packages inside your local Maven repository, type :
+ 
+```bash
+mvn install
+```
+
+## Sample usage
+
+Include the Jar file as a dependency, then import the classes :
+
+```java
+import fr.rabian.ovhApi.core.beans.*;
+```
+
+You can then create an application and its manager, and get your first consumer :
+
+```java
+Application a = new Application(AK, AS, Endpoint.ovh_eu);
+AppManager am = a.getAppManager();
+Consumer c;
+
+ScopeElement g = new ScopeElement("GET", "/*");
+List<ScopeElement> scope = new ArrayList<>();
+scope.add(g);
+                     
+try {
+    c = am.getConsumer(scope, "");
+    System.out.println(nc.getConsumerKey());
+    Scanner in = new Scanner(System.in);
+    String wait = in.nextLine();
+    System.out.println(am.sendGetReq("/me", c));
+} catch (NOKResponseException e) {
+    e.printStackTrace();
+}
+```
