added cautionary notes about nodejs versions
| NOTE: IMPORTANT - installing a higher version of nodejs (eg V20) is known to cause issues with a number of plugins and CAN adaptors. | ||
| Note: Some applications that are installed after signalk-server are known to "auto" install updated/most recent version of nodejs... | ||
| which as above breaks things .... take care to avoid this! | ||

Sorry, I think there are multiple issues in this addition:
- The previous step calls for installing NodeJS (note the capitalization) 18 and this about "higher version" and refers to V20. To me this is needlessly confusing
- Why is there one NOTE and and another note?
- I am not aware of other applications updating nodejs version - can you be more specific? And how would an end user take care to avoid thid?
This document is about installing signalk-server on a system that has no NodeJS or a previous installation, but the notes are about updating Node. Maybe we could find some other place where these notes would have a more appropriate home, like https://github.com/SignalK/signalk-server/wiki/Installing-and-Updating-Node.js ?

i did follow the instructions as presented, all good.
however when installing either influx or grafana - i believe it was the latter,
the install script - went ahead and update nodejs… (to V20) … this created two days of fault finding and unnecessary debugging with help from other signalk users.
FAQs would at best be looked at after a user encounters an issue … i was thinking “how” to make sure that as part of the install process .. that a user be alerted to beware of this …

Neither Influx nor Grafana are NodeJS based, I sincerely doubt they caused a NodeJS update.¨
Also the problem is not really NodeJS v20, instead any update of a major NodeJS version may break things and in practise requires a reinstall of the server and the plugins.

all noted, are my additions to the FAQs ok? |
