+# EXW3
+
+**TODO: Add description**
+
+## Installation
+
+  1. Add exw3 to your list of dependencies in mix.exs:
+
+        def deps do
+          [{:exw3, "~> 0.0.1"}]
+        end
+
+  2. Ensure exw3 is started before your application:
+
+        def application do
+          [applications: [:exw3]]
+        end

+
+# It is also possible to import configuration files, relative to this

+# by uncommenting the line below and defining dev.exs, test.exs and such.
+# Configuration from the imported file will override the ones defined
