+# .devcontainer setup for local development of `imgproxy`
+
+All `imgproxy` dependencies are included in the `imgproxy-base` container image. Using this image for development is recommended.
+
+If you want to develop locally without using Docker, please install: `vips`, `clang-format`,`lychee` and `lefthook`.
+
+On MacOS:
+
+```sh
+brew install vips clang-format lychee lefthook
+```
+
+Then, run:
+```sh
+lefthook install
+```
+
+# Start the devcontainer
+
+You can use [`air`](https://github.com/air-verse/air) for hot-reloading during development. Simply run: `air`.
+
+Port `8080` is forwared to the host.
+
+# Test images
+
+[test images repo](https://github.com/imgproxy/test-images.git) will be automatically cloned or pulled to `.devcontainer/images` folder before the container starts.
+
+[Try it](http://localhost:8080/insecure/rs:fit:300:200/plain/local:///kitten.jpg@png). -->
