 ### Database
 **Change name of database and credentials as you like!**
 
-- Create new database: `CREATE DATABASE locationhub;`
+- Create new database: `CREATE DATABASE dev_locationhub;`
 - Create new user for database: `GRANT ALL PRIVILEGES ON dev_locationhub.* TO 'dbuser'@'localhost' IDENTIFIED BY '1234';`
 - Import tables: `/usr/bin/mariadb -u dbuser -p1234 dev_locationhub < server/sql/tables.sql`
 
+### TTN Integration
+Create new Webhook for application. Set base url and enable "Uplink message" to api `/api/ttn/webhook`.
+Add a addidtional header: 
+- Type: `authorization` 
+- Value: `Bearer your-very-secure-token`
+
 ### Testing Webhook
 - To test the webhook use the python script `ttn-webhook-dummy.py` to send prerecorded TTN Uplinks.
 - To test the script you can use `while true; do echo -e "HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\n\r\nSuccess"; nc -l -p 8080 -q 1; done`
