Update
To update Trueno, execute the following command:
> npm update -g trueno
This will update the global NPM package.
NOTE: If you are using Trueno without the --dir flag, all the existing data will be wiped along with the installation. If you wish to keep the data either use the --dir flag or go to:
path/to/global/node_modules/trueno/lib/core/data
You will find all the data there. To use this data with a new installation, back up the directory and just point the --dir flag to it on the new installation.
