# Auto-deploy script for warp-charger.com and docs.warp-charger.com

# changed; each site is only rebuilt when files below its directory changed.

# Branch selection based on hostname:
#   stagingwww -> stagingwww.warp-charger.com branch
#   otherwise  -> master branch

# Initial setup on the server (run once as service user):

#   cd /home/www
#   git clone --depth=1 --filter=blob:none --sparse \
#       git@github.com:Tinkerforge/warp-charger.git warp-charger
#   cd warp-charger
#   git sparse-checkout set warp-charger.com firmwares documents docs.warp-charger.com
