+Lbrycrdd will use the below default data directories

+Windows < Vista: C:\Documents and Settings\Username\Application Data\lbrycrd   
+Windows >= Vista: C:\Users\Username\AppData\Roaming\lbrycrd   
+Mac: ~/Library/Application Support/lbrycrd      
+Unix: ~/.lbrycrd
+
+The data directory contains various things such as your default wallet (wallet.dat), debug logs (debug.log), and blockchain data. You can optionally
+create a configuration file lbrycrd.conf in the default data directory which will be used by default when running lbrycrdd.
+For a list of configuration parameters run `./lbrycrdd --help`. Below is a sample lbrycrd.conf to enable JSON RPC server on lbrycrdd.

+```rpcuser=lbry
