+# Ignore Windows
+
+❗️**NOTE**: A significant number of ignored window rules for the most common
+applications are [already generated for
+you](https://github.com/LGUG2Z/komorebi/#generating-common-application-specific-configurations)
+
+Sometimes you will want a specific application to never be tiled, and instead
+float all the time. You can add rules to enforce this behaviour in the
+`komorebi.json` configuration file.
+
+```json
+{
+  "float_rules": [
+    {
+      "kind": "Title",
+      "id": "Media Player",
+      "matching_strategy": "Equals"
+    }
+  ]
+}
+```
