+### Folder structure
+
+Use separate `db` and `config` directories, do not nest them:
+
+```
+data
+├── config
+└── db
+```
+
+### Permissions
+
+If you are facing permissions issues run the following commands on your server. This will change the owner and assure sufficient access to the database and config files that are stored in the `/local_data_dir/db` and `/local_data_dir/config` folders (replace `local_data_dir` with the location where your `/db` and `/config` folders are located).
+
+```bash
+sudo chown -R 20211:20211 /local_data_dir
+sudo chmod -R a+rwx /local_data_dir
+```
 
 ### Initial setup
 
 - If unavailable, the app generates a default `app.conf` and `app.db` file on the first run.
 - The preferred way is to manage the configuration via the Settings section in the UI, if UI is inaccessible you can modify [app.conf](https://github.com/jokob-sk/NetAlertX/tree/main/back) in the `/data/config/` folder directly
 
+
 #### Setting up scanners
 
 You have to specify which network(s) should be scanned. This is done by entering subnets that are accessible from the host. If you use the default `ARPSCAN` plugin, you have to specify at least one valid subnet and interface in the `SCAN_SUBNETS` setting. See the documentation on [How to set up multiple SUBNETS, VLANs and what are limitations](https://github.com/jokob-sk/NetAlertX/blob/main/docs/SUBNETS.md) for troubleshooting and more advanced scenarios.

We strongly recommend you start with or migrate to this file as your baseline and modify it to suit your specific needs (e.g., changing file paths). While there are many ways to configure NetAlertX, the default file is designed to meet the mandatory security baseline with layer-2 networking capabilities while operating securely and without startup warnings.
