I had to use a Raspberry Pi to unlock the Pinetime first, but I believe a J-Link can do that. Once a bootloader is installed using an St-Link or J-Link then the application code can be downloaded over Bluetooth using Linux or Android. Danielt supplies tools for doing this on Linux. Danielt and Lupyuen have excellent documentation.

I have a lot of experience with large computers, from mainframes to laptops, but not much experience with smaller devices. It took me a while and a learning curve but I got there.
Documentation is definitely the key to making a hackable watch more accessible to people without a microcontroller background and I'm certainly trying to do my best on the wasp-os bits. However for the overall device it is important the wiki gets as good as it can be.
As you allude to, one of the biggest challenges to get started with PineTime are that documentation on how to do the initial programming is still a bit fragmented but its getting better, there was a big reorg a few weeks back and it does look like edits are starting to flow nicely now. More work is still needed (and probably always will be) but I'd encourage anyone who does get a programmer to work to think about how the docs could be improved so it is (incrementally) easier for the next person.
