 ## Java Server
 
-Before usage please update application.properties. You will find the necessary credentials here: https://accounts.bosch-iot-suite.com/oauth2-clients. \
-You will also need a device_management subscription and a namespace. \
-Conntact the hivemq admin if you need the hivemq password. 
+### First steps
+1. First of all, you need an active [Subscription](https://accounts.bosch-iot-suite.com/subscriptions/) to the Bosch IoT Suite: 
+    - Click on new Subscription and select "Bosch IoT Device Management".
+    - Choose the Plan you want and give your subscription an Instance Name.
+
+2. You have to configure a new [OAuth2 Client](https://accounts.bosch-iot-suite.com/oauth2-clients/):
+    - Click on New OAuth2 Client.
+    - Write your Client Name, select all Options on the Client Scopes and select the Owner Option from the Organization Scopes.
+    - Click on Create.
+
+3. Update the application.properties. You will find the necessary credentials [here](https://accounts.bosch-iot-suite.com/oauth2-clients):
+    - On the OAuth2 Page click on Use and then on Spring.
+    - Copy the application.properties Part from "Define the configuration properties in application.properties:"
+    - Insert the copied application.properties in src/main/resources/application.properties (you can edit the file with VSCode).
+
+4. Insert the HiveMQ Password in application.properties in src/main/resources/application.properties
+    - Contact the HiveMQ Admin, if you need the password. 
+
+5. Create a Namespace.
+    - Go to [Subscriptions](https://accounts.bosch-iot-suite.com/subscriptions/) and choose "Go to Dashboard" and now choose "Things Dashboard".
+    - Click on Namespace and "Create new namespace"
+    - Choose a namespace name and click on Comfort and Create it.
+    - Write the new created namespace in the "bosch-iot-suite.namespace"-field in application.properties in src/main/resources/application.properties
+
+6. Copy the Test Access Token
+    - Go to [OAuth2 Clients](https://accounts.bosch-iot-suite.com/oauth2-clients/)
+    - Click on Use and copy the blue Test Access Token field.
+
+7. Go to the [Bosch IoT API](https://apidocs.bosch-iot-suite.com/?urls.primaryName=Bosch%20IoT%20Things%20-%20HTTP%20API%20(v2)) and click on Authorize. Now you can insert the Test Access Token and click on Authorize.
+
+8. Create a Thing via the [Bosch IoT API](https://apidocs.bosch-iot-suite.com/?urls.primaryName=Bosch%20IoT%20Things%20-%20HTTP%20API%20(v2))
+    - Click on Things and then on PUT /thing/{thingId}
+    - Click on Try it out.
+    - In the first field write your thingId which means: your Namespace (from Step 6), your hubId(0) and your nodeId(333). \
+     The thingId should follow this schema: ``` namespace:hubId_nodeId ```
+    - On the request body you have to enter this JSON Code:
+
+``` 
+{
+  "features": {
+    "on-off": {
+      "desiredProperties": {
+        "on": 0
+      }
+    }
+  }
+}
+```
+
+
+#### Solution ID
+If you need a Solution ID, this is how you can find it:
+ - Go to [Subscriptions](https://accounts.bosch-iot-suite.com/subscriptions/) and choose "Go to Dashboard" and now choose "Things Dashboard".
+ - Now you can copy your Solution ID.
 
-The easiest way to start is to create a thing via the Bosch API (PUT /thing/thingID). The thingID should follow this schema: namespace:hubId_nodeId \
