+@node Configuration
+@unnumbered Configuration file
+
+NNCP uses single file configuration file in @url{https://hjson.org/,
+Hjson} format. Initially it is created with @ref{nncp-cfgnew} command
+and at minimum it can look like this:
+
+@verbatim
+spool: /var/spool/nncp
+log: /var/spool/nncp/log
+
+self: {
+ id: RKOLY...KAMXQ
+ exchpub: 2NZKH...CMI7A
+ exchprv: KETPP...2OJZA
+ signpub: EXD7M...YAOFA
+ signprv: B3EMS..XMAHCQ
+ noiseprv: 3TJDF...2D7DQ
+ noisepub: MIXYN...BGNDQ
+}
+
+neigh: {
+ self: {
+ id: RKOLY...KAMXQ
+ exchpub: 2NZKH...CMI7A
+ signpub: EXD7M...YAOFA
+ noisepub: MIXYN...BGNDQ
+ }
+}
+@end verbatim
+
+And for being able to communicate with at least one other node, you just
+need to add single key to the @code{neigh} section similar to the "self".
+
+All configuration file can be separated on five sections:
+
+@menu
+* General options: CfgGeneral.
+* Self-node keypairs: CfgSelf.
+* Notifications: CfgNotify.
+* Neighbours: CfgNeigh.
+* Areas: CfgAreas.
+@end menu
