 If yes, you can refer to the steps below to remove the duplicates. Alternatively, if you would prefer to disable the Compose editing features that _this_ extension is providing, you can set the `docker.extension.enableComposeLanguageServer` setting to `false` and then restart Visual Studio Code.
 
 - [Red Hat's YAML extension](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml) (powered by [redhat-developer/yaml-language-server](https://github.com/redhat-developer/yaml-language-server))
-  1. To disable duplicates from this extension, create a JSON file with `{}` as its content and save it somewhere. Let's say it is at `/home/user/empty.json`.
-  2. Open the [Command Palette](https://code.visualstudio.com/api/ux-guidelines/command-palette) in Visual Studio Code and open "Preferences: Open User Settings (JSON)".
-  3. Set `docker.extension.enableComposeLanguageServer` to `true` by following the snippet below.
-  4. Create an object attribute for `yaml.schemas` if it does not already exist.
-  5. Inside the `yaml.schemas` object, map your empty JSON file to Compose YAML files by following the snippet below.
-  6. YAML files named `compose*y*ml` or `docker-compose*y*ml` will now no longer have the Compose schema associated with them in Red Hat's extension so Red Hat's extension will stop providing YAML features for Compose files. This admittedly is a strange way to disable YAML features for a given file but it is the only known workaround for resolving this until [redhat-developer/vscode-yaml#1088](https://github.com/redhat-developer/vscode-yaml/issues/1088) is implemented.
