+## MongoDB
+
+ezPAARSE needs a mongodb to work, it can store the admin account, PKBs cache and processing history.
+by default, 
+ezPAARSE tries to connect to a mongodb which is available on port 27017.
+
+> [!NOTE]  
+> ezPAARSE loads PKBs on mongodb. As of mongodb version 6, this feature is no longer available.
+
+### Official packages
+
+You can install mongodb on your server via [official packages](https://www.mongodb.com/docs/manual/installation/).
+
+### Docker
+
+It's easier to install mongodb at the right version with docker.
+
+```bash
+# Create mongodb image.
+# You can use other versions but this may have an impact on PKB.
+docker run -p 27017:27017 --name ezpaarse-db -d mongo:3.6.23
+# Start mongodb.
+docker start ezpaarse-db
+# Stop mongodb.
+docker stop ezpaarse-db
