+# Testing Clowder PR
+
+Download the [docker-compose.yml](https://raw.githubusercontent.com/clowder-framework/clowder/develop/docker-compose.yml) file in a new folder. Next create a .env file with the following data:
+
+```ini
+COMPOSE_PROJECT_NAME=clowder
+TRAEFIK_HOST=Host:yourmachine.ncsa.illinois.edu;
+TRAEFIK_HTTP_PORT=80
+TRAEFIK_HTTPS_PORT=443
+TRAEFIK_HTTPS_OPTIONS=TLS
+TRAEFIK_ACME_ENABLE=true
+TRAEFIK_ACME_EMAIL=youremail@ncsa.illinois.edu
+TRAEFIK_HTTP_REDIRECT=Redirect.EntryPoint:https
+CLOWDER_SSL=true
+CLOWDER_ADMINS=youremail@ncsa.illinois.edu
+```
+
+Next create a docker-compose.override.yml file:
+
+```yaml
+version: '3.5'
+
+services:
+  # point to the PR image (in this case PR-404)
+  clowder:
+    image: ghcr.io/clowder-framework/clowder:PR-404
+
+  # add any more extractors if you want
+  # extract preview image
+  imagepreview:
+    image: clowder/extractors-image-preview:latest
+    restart: unless-stopped
+    networks:
+      - clowder

+        condition: service_started
+    environment:
+      - RABBITMQ_URI=${RABBITMQ_URI:-amqp://guest:guest@rabbitmq/%2F}
+

+
+It is best practice to start with a `docker-compose pull` to make sure you have all the latest versions of the containers, followed by a  `docker-compose up -d`. This will start all containers. You should be able to go to https://yourmachine.ncsa.illinois.edu.
+
+If this is the first time running the stack (or if you removed the mongo database), you will need to create the initial user again:
+
+```bash
+docker run --rm -it \
+    --network clowder_clowder \
+    -e "FIRSTNAME=Admin" \
+    -e "LASTNAME=User" \
+    -e "ADMIN=true" \
+    -e "PASSWORD=areallygoodpassword" \
+    -e "EMAIL_ADDRESS=youremail@ncsa.illinois.edu" \
+    -e "MONGO_URI=mongodb://mongo:27017/clowder" \
+    clowder/mongo-init
+```
