-This project requires [Docker][docker] and [Node.js][node] for local development.

If you are on Windows and use VS Code, you may find it helpful to [run VS Code in a container][vs-code-container] so that you can more easily work with PHP (see more details in the [Local Development Setup section](#running-vs-code-in-a-container)).

Windows has limited support for PHP, though, so you may want to run VS Code in a container so that PHP will be more easily available (or you can choose to live without real-time error highlighting).

-##### Running VS Code in a Container
-
-The [Dev Containers extension][dev-containers-vscode] allows you to run VS Code inside a container, giving you access to a consistent environment that you can configure to include the dependencies you need. For this project, we recommend an Ubuntu container with the same PHP version as in the [Dockerfile](./Dockerfile), the LTS version of Node.js, and Docker (docker-in-docker).
-
-After installing the Dev Containers extension, you can manually create the container through the extension's UI, or you can add a configuration file at `.devcontainer/devcontainer.json`, like so:
-
-```json
-// For format details, see https://aka.ms/devcontainer.json. For config options, see the
-// README at: https://github.com/devcontainers/templates/tree/main/src/ubuntu
-{
-	"name": "Ubuntu",
-	// Or use a Dockerfile or Docker Compose file. More info: https://containers.dev/guide/dockerfile
-	"image": "mcr.microsoft.com/devcontainers/base:jammy",
-	"features": {
-		"ghcr.io/devcontainers/features/node:1": {
-			"nodeGypDependencies": true,
-			"version": "lts",
-			"nvmVersion": "latest"
-		},
-		"ghcr.io/shyim/devcontainers-features/php:0": {
-			"installComposer": true,
-			"version": "8.1"
-		},
-		"ghcr.io/devcontainers/features/docker-in-docker:2": {
-			"moby": true,
-			"azureDnsAutoDetection": true,
-			"installDockerBuildx": true,
-			"version": "latest",
-			"dockerDashComposeVersion": "v2"
-		}
-	},
-	"customizations": {
-		"vscode": {
-			"extensions": ["ValeryanM.vscode-phpsab", "whatwedo.twig", "cerzat43.twigcs"]
-		}
-	}
-
-	// Features to add to the dev container. More info: https://containers.dev/features.
-	// "features": {},
-
-	// Use 'forwardPorts' to make a list of ports inside the container available locally.
-	// "forwardPorts": [],
-
-	// Use 'postCreateCommand' to run commands after the container is created.
-	// "postCreateCommand": "uname -a",
-
-	// Configure tool-specific properties.
-	// "customizations": {},
-
-	// Uncomment to connect as root instead. More info: https://aka.ms/dev-containers-non-root.
-	// "remoteUser": "root"
-}
-```
-
-Note: after restarting in the containerized VS Code, you will need to run `npm ci` and `docker compose build` again. You may also need to delete the `theme` and `plugins` folders so that the build process can recreate them with the right file permissions for the container.
