# - Install NodeJS v6.x on Debian 9 Stretch
# ---
# - Creates the apt sources list file '/etc/apt/sources.list.d/nodesource.list' for
# - the NodeSource Node.js v6.x and also adds the NodeSource signing key to your keyring
# -
# - curl -sL https://deb.nodesource.com/setup_6.x | bash -
# -
# - Hope nodejs version 14.x will work
# -
# - nodejs 6.0 does not yet work for actuall etherpad, which ist also installed
# - on this server.
# -
curl -sL https://deb.nodesource.com/setup_14.x | bash -
apt-get update
# - Install nodejs version 6.x from repository 'deb.nodesource.com'
# -
# - Tell the apt system to install nodejs from repository deb.nodesource.com
# -
# - You should pin the external source using the origin option to assign a high
# - priority to "the external source" instead of using the release name.
# -
# - e,g: Add the following lines to your /etc/apt/preferences.d/preferences:
# -
# - Package: *
# - Pin: origin deb.nodesource.com
# - Pin-Priority: 1001
# -
if ! $(grep -E -q "^\s*Pin:\s+origin\s+deb.nodesource.com" /etc/apt/preferences.d/preferences) ; then

# - Customizing CryptPad
# -
# - In order allow a variety of features to be changed and to allow site-specific
# - changes to CryptPad apps while still keeping the git repository pristine, this
# - directory exists to allow a set of hooks to be run.
# -
# - The server is configured to load files from the '/customize/' path
# - preferentially from 'cryptpad/customize/', and to fall back to
# - 'cryptpad/customize.dist/' if they are not found.
# -
# - If you wish to customize cryptpad, please **copy**
# - '/customize.dist/' to '/customize' and then edit it there, this way you will
# - still be able to pull from (and make pull requests to (!) the git repository.
