+===============================
+
+## Generating a password
+
+For generating a password you either need opt/apache installed to be able
+to use `htpasswd -nBC 10 "" | tr -d ':\'; echo` or use install
+`contrib/python3-bcrypt` and use
+`/usr/lib/prometheus-node-exporter/gen-pass.py`. Use the generated password
+hash to fill in the skeleton under `/etc/node-exporter/config.yml`.
+
+## Using tls
+
+Generate a valid certificate according to the `config.yml` or use a proper one.
+If you use a self signed certificate you will make your prometheus scraper
+trust it.
