+# Creating the DB cluster
+
+1) Head to the [signup page](https://www.mongodb.com/cloud/atlas/register) and fill your details in, agree to the terms and click `Create your Atlas account`

+
+3) We are now done with the webpage setup, you can now open the bot config up and fill the info in accordingly:
+
+```jsonc
+ "mongodb": {
+    "protocol": "mongodb+srv://",
+    "address": "<the value you just copied (WITH THE TRAILING /)>",
+    "username": "<username>",
+    "password": "<password>"
+  },
+```
+
+You can now start the bot and use MongoDB normally.
