+; Summary of 'addpeer' versus 'connect'.
+;
+; Only one of the following two options, 'addpeer' and 'connect', may be
+; specified.  Both allow you to specify peers that you want to stay connected
+; with, but the behavior is slightly different.  By default, btcd will query DNS
+; to find peers to connect to, so unless you have a specific reason such as
+; those described below, you probably won't need to modify anything here.
+;
+; 'addpeer' does not prevent connections to other peers discovered from
+; the peers you are connected to and also lets the remote peers know you are
+; available so they can notify other peers they can to connect to you.  This
+; option might be useful if you are having problems finding a node for some
+; reason (perhaps due to a firewall).
+;
+; 'connect', on the other hand, will ONLY connect to the specified peers and
+; no others.  It also disables listening (unless you explicitly set listen
+; addresses via the 'listen' option) and DNS seeding, so you will not be
+; advertised as an available peer to the peers you connect to and won't accept
+; connections from any other peers.  So, the 'connect' option effectively allows
+; you to only connect to "trusted" peers.
+; ******************************************************************************

+; Coin Generation (Mining) Settings - The following options control the
+; generation of block templates used by external mining applications through RPC
+; calls as well as the built-in CPU miner (if enabled).
+; ------------------------------------------------------------------------------
+
+; Enable built-in CPU mining.
+;
+; NOTE: This is typically only useful for testing purposes such as testnet or
+; simnet since the difficulty on mainnet is far too high for CPU mining to be
+; worth your while.
+; generate=false
+
+; Add addresses to pay mined blocks to for CPU mining and potentially in the
+; block templates generated for the getblocktemplate RPC.  One address per line.
+; miningaddr=1yourbitcoinaddress
+; miningaddr=1yourbitcoinaddress2
+; miningaddr=1yourbitcoinaddress3
+
+; Specify the minimum block size in bytes to create.  By default, only
+; transactions which have enough fees or a high enough priority will be included
+; in generated block templates.  Specifying a minimum block size will instead
+; attempt to fill generated block templates up with transactions until it is at
+; least the specified number of bytes.
+; blockminsize=0
+
+; Specify the maximum block size in bytes to create.  This value will be limited
+; to the consensus limit if it is larger than that value.
+; blockmaxsize=750000
+
+; Specify the size in bytes of the high-priority/low-fee area when creating a
+; block.  Transactions which consist of large amounts, old inputs, and small
+; sizes have the highest priority.  One consequence of this is that as low-fee
+; or free transactions age, they raise in priority thereby making them more
+; likely to be included in this section of a new block.  This value is limited
+; by the blockmaxsize option and will be limited as needed.
+; blockprioritysize=50000
+
+
+; ------------------------------------------------------------------------------
+; Debug
+; ------------------------------------------------------------------------------
+
+; Debug logging level.
+; Valid levels are {trace, debug, info, warn, error, critical}
+; You may also specify <subsystem>=<level>,<subsystem2>=<level>,... to set
+; log level for individual subsystems.  Use btcd --debuglevel=show to list
+; available subsystems.
+; debuglevel=info
+
+; The port used to listen for HTTP profile requests.  The profile server will
+; be disabled if this option is not specified.  The profile information can be
+; accessed at http://localhost:<profileport>/debug/pprof once running.
+; profile=6061
