# Paperless-ngx > [*Paperless-ngx*][0] is a community-supported open-source document management > system that transforms your physical documents into a searchable online > archive so you can keep, well, less paper. ## Deploy with `kustomize` ```sh kubectl apply -k paperless-ngx ``` Generic resources, including the persistent volumes and pods, are defined in `paperless-ngx/paperless-ngx.yaml`. Environment-specific overrides are supplied in `paperless-ngx/kustomization.yaml`. An Ingress resource is configured in `paperless-ngx/ingress.yaml`. This deployment uses SQLite as the database engine. *Paperless-ngx* supports other engines, but SQLite is fine for a single-instance deployment with only a small number of documents. Authentication via "HTTP remote user" is enabled, and the Ingress is configured to use Authelia. This provides a single sign-on experince, since *Paperless-ngx* does not currently support LDAP or OAuth/OpenID Connect. [0]: https://docs.paperless-ngx.com/
