Walkthrough

This pull request updates the .devcontainer/README.md file to reflect infrastructure changes. The development runtime description is updated from Apache 2.4 with PHP 8.3 to FrankenPHP (Caddy) with PHP 8.4. Node.js version is incremented from 22 to 24. The sample devcontainer configuration is modified by removing Apache-related features and replacing them with common-utils and github-cli, while also removing the overrideFeatureInstallOrder configuration block. Documentation links are redirected to point to the Winter Docker image README persist-data section and FrankenPHP environment variables documentation.

⚠️ Potential issue | 🟡 Minor

Example contradicts “disable bootstrap-winter” instruction

Line 45 says to disable by commenting out the feature, but Line 52 still shows ./local-features/bootstrap-winter enabled in the example. This can mislead users into keeping bootstrap enabled.

Suggested doc fix

     "features": {
         "ghcr.io/devcontainers/features/common-utils:2": {},
         "ghcr.io/devcontainers/features/github-cli:1": {},
         // Comment the following feature if you wish to bootstrap and configure Winter manually (ie. you wish to use this for your own project)
-        "./local-features/bootstrap-winter": "latest"
+        // "./local-features/bootstrap-winter": "latest"
     },
