+# Neo4J ADCY5
+This directory in the repository explains how to setup and create the Neo4J database.
+
+## Quickstart
+
+1. Run the command `python main.py` to create the JSON file which performs data collection accross the internet.
+2. Run the command `python ParseJson.py` creates the CSV.
+3. Open the `load.cql` file to create the query from the `output.csv` to run on the cloud Neo4J.
+
+## Cloud Storage
+The data is located on https://console.neo4j.io/ and you can find the authentication, urls, and secrets in `keys.txt`.
+
+## Install
+- Run `./install.sh`
+- Run the command `./neo4j-community-5.17.0/bin/neo4j status` to see the status of the Neo4J database.
+
+## Visualize
+
+Run this query to produce a visualization.
