 ![Raspberry PI Logo](/assets/img/RaspberryPI_Logo.webp){: .right width="100" }
 In order to run TerrariumPI you first need a working Raspberry PI with the '[Raspberry Pi OS Lite (Legacy)](https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-os-legacy)' image. Make sure you are using the **Legacy** version! This is Debian Buster.
 This is very important, as the Desktop and/or the new OS version will not work well with the GPIO pins and Raspberry PI cameras.
 
 Also **64bit is not supported** due to missing mmal code which is needed for the webcams.

 Download and instal the [Raspberry Pi Imager](https://www.raspberrypi.org/software/) to prepare your SD card. Make sure you have a SD card of at least 4GB of size. Bigger is better :) Make sure you select **Raspberry Pi OS Lite (legacy)** from the other Raspberry Pi OS images.

Here you enter your Wifi settings, pi password etc. Use this to install the Raspberry PI headless. Add the SD card in the Raspberry PI and withing a minute you should have a running Raspberry PI.

-# Migration from V3 to V4
+## Migration from V3 to V4
 
 There is **no real migration** from version 3 to version 4. The changes are to big. So that means you have to install TerrariumPI v4 as it was a new PI. These migrations steps will only copy the *existing relay history data* from V3 to V4 so that the total power and water usages is still there. And the total costs are still correct. This is all what will be migrated.
 
 If you do **not care** about your relay history, you can just skip this migration. This is the **only** data that will be migrated!
 
-## Backup
+### Backup
 
 So make sure you have **stopped** the old TerrariumPI. And rename the folder `TerrariumPI` to `TerrariumPI.old`. This way you have a backup of your existing working setup.
 
 1. Stop TerrariumPI 3. [Wiki](https://github.com/theyosh/TerrariumPI/wiki/FAQ#how-to-stop-terrariumpi)
 
 2. Make a backup of existing version. `mv /home/pi/TerrariumPI /home/pi/TerrariumPI.old`
 
-## First setup
+### First setup
 
 Now, install TerrariumPI v4 as [described here](#terrariumpi). And then you need to set it up as you want. So that means adding at least all the relays you want to use/migrate. When that is done, shutdown TerrariumPI 4 and continue with the last migrations step.
