+# How-To
+
+This is a quick setup-guide on how-to to use ClamAV with mounting directories using NFS shares and using the integrated cron job to scan these mounted folders.
+
+:::info
+
+- ClamAV TrueCharts App
+- NFS Shares of the folders you want to scan
+
+:::
+
+## Guide
+
+### Step 1
+
+Setup App Name and Configuration as necessary, but where you deviate from defaults is by `Enable cronjob` at the <u>ClamAV Cron Configuration</u> section.
+
+- To generate a cron schedule one can use a website like [cronhub](https://crontab.cronhub.io) or [crontab.guru](https://crontab.guru)
+

+
+**Note the added directory to `Extra Args`, this is where your scanned directories will go**
+
+### Step 2
+
+Add your scanned directories using `Configure Additional Storage` and make sure your mounted directories match the directory in the `Extra Args` section above

+
+That's it, without a GUI having the cron job is the easiest way to have your ClamAV running in the background at specific times.
+
