# INSTRUCTIONS
#
# 1. Install wfrog, get it up running with your weather station
# 2. Locate your wfrog.csv file (wfrog creates after 10 mins)
# 3. cd /etc/munin/plugins/
# 4. ln -s /usr/share/munin/plugins/wfrog wfrog_temp
# 4. ln -s /usr/share/munin/plugins/wfrog wfrog_pressure
# 5. etc..
# 6. reload munin-node ;-)
# In case you need to change this.
