+## 🤖 Config File
+
+RustScan uses a Config file to make things easier for you. And to also improve itself.
+The config file is used as the basis of the _adaptive learning_ mechanisms. This means that RustScan _learns_ from your scans and improves itself over time. (Don't worry, no bloated AI framework here 😉)
+
+The config file should be placed in APPDIRS. To find this folder, run RustScan and look out for RustScan saying "couldn't find config at <location>". That location is where your config file should be.
+
+Once you have this location, copy and paste this:
+
+```toml
+
+# The top ports
+[top_ports]
+80, 60, 443
+```
