# Overrides¶

Useful when you want to add extra build commands to the default _build.json file. This allows you to append new commands at the bottom of the project build configuration.

## Example¶

Inside the _package.json we can add a overrides section like so:

// _package.json
"requires": [
{
"name": "Zefiros-Software/ArmadilloExt",
"version": ">=1.2.0",
"overrides": [
{"project": "Armadillo",
"do": [
{"defines": "DEBUG"}
]}
]
}
]


Now we have added the DEBUG symbol to the project in every configuration.
