# Neutrino Base Preset |
|||
|
|||
This [neutrino](https://github.com/mozilla-neutrino/neutrino) preset is abstract and should not be |
|||
used directly to build a JavaScript project. Rather, this preset contains shared configuration that |
|||
is extended by all other core neutrino presets. |
|||
|
|||
Modify this preset if there is shared configuration that should be propagated to all other core |
|||
neutrino presets. This preset contains the bulk of the shared Webpack and ESLint configuration. |
