+[Service]
+# Here you must set the ABSOLUTE path to the DIRECTORY where node is (and npm)
+# If you are using nvm should be some similar to:
+# /home/$user/.nvm/versions/node/$version/bin
+Environment=NODE_PATH=/usr/bin/
+# Here you must set the port where you would like that this service runs
+Environment=BLENDB_PORT=3001
+# Here you must set the user that should run the service
+# We DO NOT recomend run as root but should work properly as root too
+# We recomend create a separeted user named blendb, but any user should work
+User=blendb
+# Here you must set the path to the BLENDB project DIRECTORY
+# We recomend use the ABSOLUTE path
+# Runing pwd on the git repository should give the right path
+WorkingDirectory=/opt/blendb/
+ExecStart=/bin/bash -c "PATH=$PATH:${NODE_PATH}; PORT=${BLENDB_PORT} npm start"
