A lot of people already use adblocker plugins within their desktop browsers, but what if you are using your (smart) phone, tablet, watch or any other (wlan) gadget!? Getting rid of annoying ads, trackers and other abuse sites (like facebook) is simple: block them with your router. When the DNS server on your router receives DNS requests, you will sort out queries that ask for the resource records of ad servers and return a simple 'NXDOMAIN'. This is nothing but Non-eXistent Internet or Intranet domain name, if domain name is unable to resolved using the DNS server, a condition called the 'NXDOMAIN' occurred.

Change the DNS backend to 'unbound':
No further configuration is needed, adblock deposits the final blocklist 'adb_list.overall' in '/var/lib/unbound' by default.
To preserve the DNS cache after adblock processing please install the additional package 'unbound-control'.
Change the DNS backend to 'bind':
Adblock deposits the final blocklist 'adb_list.overall' in '/var/lib/bind' by default.
To preserve the DNS cache after adblock processing please install the additional package 'bind-rdnc'.
To use the blocklist please modify '/etc/bind/named.conf':
Change the DNS backend to 'kresd':
Adblock deposits the final blocklist 'adb_list.overall' in '/etc/kresd', no further configuration needed.
Please note: The knot-resolver (kresd) is only available on Turris devices and does not support the SafeSearch functionality yet.
Use restrictive jail modes:
You can enable a restrictive 'adb_list.jail' to block access to all domains except those listed in the whitelist file. Usually this list will be generated as an additional list for guest or kidsafe configurations (for a separate dns server instance). If the jail directory points to your primary dns directory, adblock enables the restrictive jail mode automatically (jail mode only).
Manually override the download options:
By default adblock uses the following pre-configured download options:
To override the default set 'adb_fetchparm' manually to your needs.
Enable E-Mail notification via 'msmtp':
To use the email notification you have to install & configure the package 'msmtp'.
Modify the file '/etc/msmtprc':
Finally enable E-Mail support and add a valid E-Mail receiver address in LuCI.
Service status output:
In LuCI you'll see the realtime status in the 'Runtime' section on the overview page.
To get the status in the CLI, just call /etc/init.d/adblock status or /etc/init.d/adblock status_service:
The 'last_run' line includes the used start type, the run duration, the memory footprint after DNS backend loading (total/free/available) and the date/time of the last run.
Edit, add new adblock sources:
The adblock blocklist sources are stored in an external, compressed JSON file '/etc/adblock/adblock.sources.gz'.
This file is directly parsed in LuCI and accessible via CLI, just call /etc/init.d/adblock list:
To add new or edit existing sources extract the compressed JSON file gunzip /etc/adblock/adblock.sources.gz.
A valid JSON source object contains the following required information, e.g.:
Add an unique object name, make the required changes to 'url', 'rule', 'size' and 'descurl' and finally compress the changed JSON file gzip /etc/adblock/adblock.sources to use the new source object in adblock.
Please note: if you're going to add new sources on your own, please make a copy of the default file and work with that copy further on, cause the default will be overwritten with every adblock update. To reference your copy set the option 'adb_srcarc' which points by default to '/etc/adblock/adblock.sources.gz'
Please note: when adblock starts, it looks for the uncompressed 'adb_srcfile', only if this file is not found the archive 'adb_srcarc' is unpacked once and then the uncompressed file is used

Have fun!
