M5 Installing LineageOS?

I’m currently building LineageOS for the M5, but I’m not sure about instillation instructions as what I’m finding appears to be specific to a phone where there’s a recovery image and then the actual OS Image. Additionally the instructions use ‘adb’ command to communicate with an Android device. My BananaPi M5 is currently nothing, as it has a blank SD Card I’m wanting to write the OS to, an OS which is a compressed zip file.

If someone could point me in the direction of install instructions specific to the M5 I’d be really grateful

thanks
