+# php83-alpine
+
+## What is this?
+
+This is a custom build based on PHP 8.3's Alpine docker image, with changes to make Laravel back-end testing easily possible.
+
+## Quick start
+
+In order to build and then test the container:
+
+    docker buildx build . --platform linux/amd64 -t nicoverbruggen/php83-alpine \
+    && docker run -it nicoverbruggen/php83-alpine sh
+
+You may omit the `--platform` flag if you wish to build a container for your own architecture, but there may be issues with dependencies.
+
+## Automatic builds
+
+The automatically build the container and have it pushed, you must:
+
+* Tag the commit you wish to build
+* Create a new release with said tag
+
+The Docker action will automatically build the release and push it under that tag to Docker Hub.
+
+## Where can I find it?
+
+You can find the image on Docker Hub here: https://hub.docker.com/r/nicoverbruggen/php83-alpine.
