+# if you want to provide default values for your application for
+# third-party users, it should be done in your "mix.exs" file.
+
+# You can configure your application as:

+#     config :bitcoinex, key: :value
+#
+# and access this configuration in your application as:

+#     Application.get_env(:bitcoinex, :key)

+# You can also configure a third-party app:
+#
+#     config :logger, level: :info
+#
+
+# It is also possible to import configuration files, relative to this
+# directory. For example, you can emulate configuration per environment
+# by uncommenting the line below and defining dev.exs, test.exs and such.
+# Configuration from the imported file will override the ones defined
+# here (which is why it is important to import them last).
