This is a very small post to remember how to use a local package when it has been already publish to packagist.org.
Basically you need to tell composer from where to pull the code, the next snippet shows how to do it:
{
"repositories": [
{
"type": "path",
"url": "../code/my-awesome-package",
"packagist.org": false
}
],
"require": {
"my/awesome-package": "@dev"
}
}
