How to start building e/OS for a custom phone?

/e/OS Devices UnOfficial Builds

My question is rather simple. I have a phone which isn’t in the supported device list.
Where should I start if I want to try to build e/OS for my phone ?

  • Find a supported device with the same processor and try that image?
  • Any other details to take care of?
