[Installation] Error on yarn run build if memory < 2Go

On a LXC container Ubuntu 20.04 with memory of 512MB, I encountered this error on yarn run build:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

With memory of 2GB this error does not happend.

Maybe it could be usefull to give memory prerequiste in documentation.

Versions

• Ubuntu 20.04 in a LXC container
