+# NDC Elixir SDK
+
+This is an Elixir package that wrapps any NDC-compliant API.
+It's host-agnostic and quite flexible-through-configuration so that it can reach NDC hosts with a certain flexibility.
+
+**TODO: Add description**
+
+## Installation
+
+If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
+
+  1. Add ndc_ex_sdk to your list of dependencies in `mix.exs`:
+
+        def deps do
+          [{:ndc_ex_sdk, "~> 0.0.1"}]
+        end
+
+  2. Ensure ndc_ex_sdk is started before your application:
+
+        def application do
+          [applications: [:ndc_ex_sdk]]
+        end
