 # Usage:
-# One option is to locate this file in the same directory the zebrad binary is
+#     zebrad generate -o myzebrad.toml
-# called from, if the default name zebrad.toml is used the app will load the new

-# configuration automatically. For example if you generate with:
+#
-# zebrad generate -o zebrad.toml
+#     zebrad generate -o zebrad.toml
-# Edit the file as needed then execute the following to connect using
+#     zebrad start
-# the new configuration, default values will be overwritten:
+#
-# zebrad connect
+# If there is no -c flag on the command line, zebrad looks for zebrad.toml in
-# If you generated with a different name or location then -c flag is required
+# the current directory. If that file does not exist, zebrad uses the default
-# to load the new configuration:
+# config.
-# zebrad generate -o myzebrad.toml

-# zebrad -c myzebrad.toml connect
