 ## Overview
 
-`go-hapingest` is a specialized file server designed to simplify bulk importing of FHIR data into a HAPI server. It makes sure that data is bulk imported in the correct order by creating multiple manifests based on what thr resources depends on. It is only made to handle ndjson files, which are commonly used in FHIR bulk imports.

It is only made to handle ndjson files, which are commonly used in FHIR bulk imports.
 
 You can run `go-hapingest` as a Docker container, mounting your FHIR data files to the `/fhir-data` directory within the container. This approach simplifies access to large datasets and facilitates their import directly into the HAPI server by letting the HAPI server fetch the content from the fileserver.
