 you can build the app yourself like this:
 
 ```
-go build -o password-generator ./
+go build ./
 ```
 
 NOTE: If you build the app manually in go, like shown in this example, it will probably not run, since it misses a writeable `/data` directory.
+You can set the counterFile by environment variable `COUNTER_FILE`, like this:
+```
+COUNTER_FILE=./counter.txt ./Web-Password
+```
 
+## debuging the app
+
+You can turn on debug mode via environment variable `DEBUG`
+```
+DEBUG=true ./Web-Password
+```
