-<!-- PREREQUISITES -->
-## Prerequisites
-### iDRAC version
-
-This Docker container only works on Dell PowerEdge servers that support IPMI commands, i.e. < iDRAC 9 firmware 3.30.30.30.
-
-### To access iDRAC over LAN (not needed in "local" mode) :
-
-1. Log into your iDRAC web console
-
-![001](https://user-images.githubusercontent.com/37409593/210168273-7d760e47-143e-4a6e-aca7-45b483024139.png)
-
-2. In the left side menu, expand "iDRAC settings", click "Network" then click "IPMI Settings" link at the top of the web page.
-
-![002](https://user-images.githubusercontent.com/37409593/210168249-994f29cc-ac9e-4667-84f7-07f6d9a87522.png)
-
-3. Check the "Enable IPMI over LAN" checkbox then click "Apply" button.
-
-![003](https://user-images.githubusercontent.com/37409593/210168248-a68982c4-9fe7-40e7-8b2c-b3f06fbfee62.png)
-
-4. Test access to IPMI over LAN running the following commands :
-```bash
-apt -y install ipmitool
-ipmitool -I lanplus \
-  -H <iDRAC IP address> \
-  -U <iDRAC username> \
-  -P <iDRAC password> \
-  sdr elist all
-```

-<!-- TROUBLESHOOTING -->
-## Troubleshooting
-
-If your server frequently switches back to the default Dell fan mode:
-1. Check `Tcase` (case temperature) of your CPU on Intel Ark website and then set `CPU_TEMPERATURE_THRESHOLD` to a slightly lower value. Example with my CPUs ([Intel Xeon E5-2630L v2](https://www.intel.com/content/www/us/en/products/sku/75791/intel-xeon-processor-e52630l-v2-15m-cache-2-40-ghz/specifications.html)) : Tcase = 63°C, I set `CPU_TEMPERATURE_THRESHOLD` to 60(°C).
-2. If it's already good, adapt your `FAN_SPEED` value to increase the airflow and thus further decrease the temperature of your CPU(s)
-3. If neither increasing the fan speed nor increasing the threshold solves your problem, then it may be time to replace your thermal paste
