Customization logo/name on webpage

I am attempting a rather tedious way to customize the webpage to reflect that it is an internal deployment by editing the .env file in /ASKCOSv2/askcos-vue-nginx, as well as some of the .vue files. I suspect though with an update this could be overwritten (the hierarchy for the home.vue content has e.g. changed from january release to the recent one). Searching the documentation about customization only leads info on full versus partial deplayment, otherwise to v1 documentation where a precisely such a customization is mentioned, but now obsolote.

Is there more documentation coming for this process?
