 ## Operations on Neo4j
 
-### Import Neo4j Dump Locally in Docker

+To create a dump in Neo4j running in a Docker container:
+
+- set the database to maintenance mode, see above

-- copy the dump into the running Docker container: `docker cp /path/to/dump <docker-image>:/existing-directory-in-docker/`
-- connect to the Docker containers Neo4j terminal: `docker exec -it neo4j bash`
-- to load the dump into the database we need the following command in this terminal: `neo4j-admin load --expand-commands --database=graph.db --from /backups/neo4j-dump --force`
-- leave the terminal by entering: `exit`
