 ### File detection
 
-By default, to avoid mishandling non-Ansible YAML files, the Ansible Language is not associated with any file extensions by default. To change this behavior you can add a `"file_types"` section to the Zed settings inside your project (`.zed/settings.json`) or your Zed user settings (`~/.config/zed/settings.json`) to match your folder/naming conventions.

+If your inventory file is in the YAML format, you can either:
+
+- Append the `ansible-lint` inventory json schema to it via the following comment at the top of your inventory file:
+
+```yml
+# yaml-language-server: $schema=https://raw.githubusercontent.com/ansible/ansible-lint/main/src/ansiblelint/schemas/inventory.json
+```
+
+- Or configure the yaml language server settings to set this schema for all your inventory files, that match your inventory pattern, under your Zed settings ([ref](https://zed.dev/docs/languages/yaml)):
+
+```json
+"lsp": {
+    "yaml-language-server": {
+      "settings": {
+        "yaml": {
