To use the mc2se command, follow the syntax below:

mc2se -i schematic.litematica -o outputfile -d definitions.json

Here's a breakdown of the command:

• -i schematic.litematica: Specifies the input file, in this case, schematic.litematica.
• -o output.sbc: (optional) Specifies the output file name. If not provided, the default name will be output.sbc.
• -d definitions.json (optional): Specifies the output file for the block definitions. You can replace definitions.json with your desired file name.

The definitions file will always generate at the location if not found

Make sure to replace schematic.litematica with the actual name of your input file and output.sbc with your desired output file name.
