+`DEFAULT_DATABASE` specifies the database name to use for graph operations. This is particularly important for Neo4j 5+ users:
+
+- **Neo4j 5+**: The default database name is `neo4j` (not `default_db`)
+- **Neo4j 4**: The default database name is `default_db`
+- **FalkorDB**: The default graph name is `default_db`

+
+Or add to your `.env` file:

+```
+DEFAULT_DATABASE=neo4j

+
+### Performance Configuration

 `USE_PARALLEL_RUNTIME` is an optional boolean variable that can be set to true if you wish
 to enable Neo4j's parallel runtime feature for several of our search queries.
 Note that this feature is not supported for Neo4j Community edition or for smaller AuraDB instances,

+## Troubleshooting
+
+### "Graph not found: default_db" Error
+
+If you encounter the error `Neo.ClientError.Database.DatabaseNotFound: Graph not found: default_db`, this typically occurs with Neo4j 5+ where the default database name is `neo4j` instead of `default_db`.
+
+**Solution:**
+Set the `DEFAULT_DATABASE` environment variable to `neo4j`:
+
+```bash
+export DEFAULT_DATABASE=neo4j
+```
+
+Or add it to your `.env` file:
+```
+DEFAULT_DATABASE=neo4j
+```
+
+This tells Graphiti to use the correct database name for your Neo4j version.
