=== Setup



This is for Neo4j version: {target-db-version}



ifeval::[{use-plugin} != false]

Required plugins: {use-plugin}

endif::[]



ifeval::[{demodb} != false]

The database is also available on https://demo.neo4jlabs.com:7473

Load graph data via the following:



ifeval::[{data} != false]

==== Data files: `{data}`



Import flat files (csv, json, etc) using Cypher's https://neo4j.com/docs/cypher-manual/current/clauses/load-csv/[`LOAD CSV`], https://neo4j.com/labs/apoc/[APOC library], or https://neo4j.com/developer/data-import/[other methods].

endif::[]



ifeval::[{use-dump-file} != false]

==== Dump file: `{use-dump-file}`



* Drop the file into the `Files` section of a project in Neo4j Desktop. Then choose the option to `Create new DBMS from dump` option from the file options.



* Use the neo4j-admin tool to load data from the command line with the command below.



[source,shell,subs=attributes]

----

bin/neo4j-admin load --from {use-dump-file} [--database "database"]

----



* Upload the dump file to Neo4j Aura via https://console.neo4j.io/#import-instructions

endif::[]



ifeval::[{use-load-script} != false]

==== Data load script: `{use-load-script}`



[source,shell,subs=attributes]

----

bin/cypher-shell -u neo4j -p "password" -f {use-load-script} [-d "database"]

----



Or import in Neo4j Browser by dragging or pasting the content of {use-load-script}.

endif::[]



ifeval::[{zip-file} != false]

==== Zip file



Download the zip file link:{repo}/raw/master/{name}.zip[{name}.zip] and add it as "project from file" to https://neo4j.com/developer/neo4j-desktop[Neo4j Desktop^].
