Please note NodeManager cannot be used as an arduino library since requires access to your MySensors configuration directives, hence its files have to be placed into the same directory of your sketch.
## Upgrade
* Download the package
* Replace the NodeManager.cpp and NodeManager.h of your project with those just downloaded
* Review the release notes in case there is any manual change required to the existing sketch or config.h file
# Configuration
NodeManager configuration includes compile-time configuration directives (which can be set in config.h), runtime global and per-sensor configuration settings (which can be set in your sketch) and settings that can be customized remotely (via a special child id).
## Setup MySensors
Since NodeManager has to communicate with the MySensors gateway on your behalf, it has to know how to do it. Place on top of the `config.h` file all the MySensors typical directives you are used to set on top of your sketch so both your sketch AND NodeManager will be able to share the same configuration.
