i'm not sure if you are even reading my notes but i literally just built and am running my realy relay on wss://nostr.realy.lol this evening and you already have access to read and write to it if your client auths to confirm you are one of my follows

it took a bit over a minute including download time to build it on a 1gb memory VPS

you should be able to get any Go based relay to build from source in even as small as 512Mb of memory
