+# Setting Limits for your Site
+
+Frappe v7 has added support for setting limits and restrictions for your site.
+These restrictions are set in the `site_config.json` file inside the site's folder. 
+
+	{
+	 "db_name": "xxxxxxxxxx",
+	 "db_password": "xxxxxxxxxxxx",
+	 "limits": {
+	  "emails": 1500,
+	  "space": 0.157,
+	  "expiry": "2016-07-25",
+	  "users": 1
+		}
+	}
+
+You can set a limit by running:
+
+	bench --site [sitename] set-limit [limit] [value]
+
+You can set multiple limits at the same time, by running 
+	
+	bench --site [sitename] set-limits --limit [limit] [value] --limit [limit-2] [value-2]
+
+The valid limits you can set are: 
+
+- **users** - Limit on the number of maximum users for a site
+- **emails** - Limit on the number of emails sent per month from the site
+- **space** - Limit on the maximum space the site can use (GB)
+- **email_group** - Limit on the maximum number of members allowed in an Email Group
+- **expiry** - Expiry date for the site (YYYY-MM-DD within quotes)
+
+Example:
+
+	bench --site site1.local set-limit users 5
+
+You can check your usage by opening the "Usage Info" page from the toolbar / AwesomeBar. A limit will only show up on the page if it has been set.
