+# Pyencrypt Django Example
+
+This example shows how to use `pyencrypt` with Django.
+
+## How to use
+```shell
+docker compose up -d
+```
+
+## Test
+* runserver: `curl http://127.0.0.1:8001/account/login/?username=admin&password=admin`
+* gunicorn: `curl http://127.0.0.1:8002/account/login/?username=admin&password=admin`
+
+## Note
+* `manage.py` shouldn't be encrypted.
+* `gunicorn.py` shouldn't be encrypted.
+
+### Loader
+* Copy `encrypted/loader*.so` to where `manage.py` is located.
+* Add `import loader` at the top of `<project>/__init__.py`.
+* Don't forget to remove `encrypted` and `build` directory.
+
+### Docker
+* For preventing to extract origin layer from image, using [`scratch`](https://docs.docker.com/build/building/base-images/#create-a-base-image) to convert image to single layer.
+  > [docker: extracting a layer from a image - Stack Overflow](https://stackoverflow.com/questions/40575752/docker-extracting-a-layer-from-a-image)
+* Remember to specify `WORKDIR`, `ENTRYPOINT` and other in `Dockerfile` again after `scratch`.
