+# IDRAC Fan Controller Docker Image
+
+To use, 
+
+`docker run -e IDRAC_HOST=<host ip> -e IDRAC_USER=<username> -e IDRAC_PW=<password> -e FANSPEED=<hex fan speed> alombardo4/idrac-fan-control:latest`
+
+`FANSPEED` should be set as a hex value, e.g. `0x05`
+
+Example `docker-compose.yml`:
+
+```yml
+version: '3'
+
+services:
+  fan-controller:
+    image: alombardo4/idrac-fan-control
+    environment:
+      - IDRAC_HOST=192.168.1.100 # override to the IP of your IDRAC
+      - IDRAC_USER=root # set to your IPMI username
+      - IDRAC_PW=calvin # set to your IPMI password
+      - FANSPEED=0x05 # set to the hex value you want to set the fans to (from 0 to 100)
+```
