 # HITO—The Health IT Ontology
+
+The source of truth for HITO, excluding software products and related attributes, whose source is the database initially filled by <https://github.com/hitontology/database>.
+
+To create a combined file, execute the `combine` script, which creates `/tmp/hito-all.nt` and `/tmp/hito-all.ttl` (including possibly outdated software products).
+This file can then be uploaded to the HITO SPARQL endpoint:
+
+1. Login to <https://hitontology.eu/conductor/>
+2. Delete graph http://hitontology.eu/ontology at Linked Data -> Graphs -> Graphs
+3. Upload the file at Linked Data -> Quad Store Upload
+
+Warning: This is the old procedure and will not include updated software products from the database.
