+## Ncrack Deployment & Configuration
+
+#### Setup with custom files:
+If you want to use your own files within the ncrack scan, you have to create a secret first:
+
+```bash
+kubectl create secret generic --from-file users.txt --from-file passwords.txt ncrack-lists
+```
+
+<b> IMPORTANT: Use an extra empty line at the end of your files, otherwise the last letter of the last line will be omitted (due to a bug in k8) </b>
+
+
+Now we created a secret named "ncrack-lists". 
+But before we can use the files, we have to install the ncrack ScanType:
+
+```bash
+cat <<EOF | helm install ncrack ./scanners/ncrack --values -
+scannerJob:
+  extraVolumes:
+    - name: ncrack-lists
+      secret:
+        secretName: ncrack-lists
+  extraVolumeMounts:
+    - name: ncrack-lists
+      mountPath: "/ncrack/"
+EOF
+```
+
+This enables us now to refer to our files via "/ncrack/<file>" in the scan.yaml.
+
+For a full example on how to configure ncrack with your custom files against a ssh service, see the "dummy-ssh" example.
+
+#### Basic setup (no files can be mounted):
+
+The Ncrack ScanType can be deployed via helm:
+
+```bash
+helm upgrade --install ncrack ./scanners/ncrack/
+```
+
+#### Delete Ncrack ScanType:
+
+```bash
+helm delete ncrack
+```
+
+#### Options
+
+All additional options for ncrack can be found on [Ncrack Documentation].
