+# Django and Minio with Docker Compose
+
+Spin up a mock S3 bucket with Minio used to serve Django static files locally.
+
+### Spin up
+
+Place your Docker network gateway IP in `.env`. And spin up the docker containers.
+
+```
+docker network inspect bridge
+docker-compose up
+```
+
+### Tear down
+
+```
+docker-compose down
+docker volume prune
+```
+
+### Troubleshooting
+
+If you are using Chrome and you are seeing a CORS header issue in the console, try running Chrome temporarily with web security disabled (only for development purposes).
+
+```
+## on Linux
+google-chrome --args --user-data-dir="./test" --disable-web-security
+```
