# Development Environment | Skeleton

Important

These docs are compatible only with Hadron v3, using [Grav v2](https://getgrav.org/blog/grav-2-stable-released) & [Quark2](https://github.com/getgrav/grav-theme-quark2), as there are significant changes in structure and functionality.

You can find the Hadron v2 Documentation either on the [Wayback Machine](https://web.archive.org/web/20260702141259/https://usehadron.dev/en/docs) or on the [GitHub Repository](https://github.com/Crabston/grav-skeleton-hadron/tree/2.2.1/pages/06.docs).

 Tip

Also check out our setup guide: [Docs / Skeleton / Setup](https://usehadron.dev/docs/skeleton/setup)

## Local overrides

Create a file at `/user/env/localhost/config/system.yaml` to override the default `user/config/system.yaml` for configuration in the development environment:

```yaml
force_ssl: false      # If the development site doesn't use SSL
cache:
    enabled: false    # Disable cache for development
    check:
        method: file  # Allow updating pages without clearing cache
images:
    cache_all: false  # Disable image cache for development
twig:
    cache: false      # Disable twig cache for development
    debug: true       # We want to display debug messages
    auto_reload: true # We may be editing twig files
errors:
    display: 1        # Display full backtrace if there are errors
debugger:
    enabled: true     # Debugger is handy to have
    censored: false   # We may want to see secure content in debugger
session:
    secure: false     # If the development site doesn't use SSL
    httponly: false   # If the development site doesn't use SSL
assets:               # Disable pipelines to get all assets separately
    css_pipeline: false
    js_pipeline: false
    js_module_pipeline: false

strict_mode: # These settings help you to keep your site updated to use the latest standards
    yaml_compat: false
    twig_compat: false
    blueprint_compat: false
```
