+## Usage
+
+### Prebuilt images (default)
+
+By default, the devcontainer will use the prebuilt base images from [GHCR](https://github.com/LayerZero-Labs/devtools/pkgs/container/devtools-dev-base).
+
+### Local images
+
+If the prebuilt images are not available or not accessible, or if work on the base images needs to be tested in a devcontainer, they can be built locally.
+
+To do this, use the provided `devcontainer.local.json` instead of the `devcontainer.json`
