 The knot-resolver (kresd) is only available on turris omnia devices. Currently there's no package for kresd in the official LEDE / OpenWrt package repository.

 Adblock deposits the sorted and filtered block list (adb_list.overall) by default in '/tmp' where DNSCrypt-Proxy can find them.
 The blacklist option is not supported by default, because DNSCrypt-Proxy is compiled without plugins support.
 Take a custom LEDE build with plugins support to use this feature:
-
+<pre><code>
 edit '/etc/config/dnscrypt-proxy' and add the following option per dnscrypt-proxy instance:
   list blacklist 'domains:/tmp/adb_list.overall'
