I'd recommend this as a great time to start building directly from the source (either LOS or AOSP) so you can provide yourself with updates, including Android Security Bulletins, as they are merged in to LOS or AOSP.

You won't get any device-specific updates or bugfixes without applying them yourself (or going out of tree), but someone already did the hard work since it's an official device and has essentially full functionality. You'll be able to keep your device supported until Lineage drops the version.

Curiously, which device did you purchase?

It's based on using an AWS instance; build times are in the order of:

"1.75 hours on a c5.4xlarge. 5 hours when Chromium is also needed"

It was the Redmi Note 5 (Whyred). They're pretty popular in India and a low cost option in Australia.

So, where does one start, and what's the process?

I'd be looking to get a nexus 5x to run 17.1

To start, https://wiki.lineageos.org/devices/bullhead/build but you won't get 17.1 support from official Lineage sources. The most you can do is the latest 15.1 with the last ASB merge from Google, but at that point you may as well find the last official and install.

I'd recommend looking for other 'trustworthy' developers who are working on your device in the open. You can install their pre-compiled builds or you can use their sources for your own builds. There are unofficial builds of Android 17.1 on XDA [0].
