+# agate-gemini docker image
 
-A gemini server using Agate
+A Gemini server using Agate. 
+
+This image is created having in mind to be used with a Traefik proxy server which will deal with the certication. That's why no certification is created inside the image in build time.
+
+To use it with Traefik and docker-compose you need to create two files with the following content in the same folder.
+
+.env
+```
+PROJECT_NAME=mygemini
+HOSTNAME=mygemini.demo.com
+```
+
+docker-compose.yml
+```yaml
+version: "3"
+
+services:
+  agate:
+    image: walkero/agate-gemini
+    container_name: "${PROJECT_NAME}_agate"
+    environment:
+      HOSTNAME: ${HOSTNAME}
+    volumes:
+      - ./content:/home/gemini/content
+    labels:
+      - "traefik.enable=true"
+      - traefik.tcp.routers.${PROJECT_NAME}_gemini.entrypoints=gemini
+      - traefik.tcp.routers.${PROJECT_NAME}_gemini.rule=HostSNI(`*`)
+      - traefik.tcp.routers.${PROJECT_NAME}_gemini.service=${PROJECT_NAME}_gemini
+      - traefik.tcp.services.${PROJECT_NAME}_gemini.loadbalancer.server.port=1965
+```
+
+To create the container you just need to run:
+```
+docker-compose up -d
+```
+
+Your gemtext files should be added at the `content` folder. Those are accessible from the container as well.
