 VSCode Remote SSH installs some files into your home directory on the server, in a
 folder called `.vscode-server`. This will not work if you experience this (rather
 common) problem: {ref}`read-write-access`. It is therefore recommended that you move the
 `.vscode-server` folder to a directory where you always have read-write access and then
 create a symbolic link to that folder in your actual home folder. Do this as follows:
