+## Installation
+
+If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
+
+ 1. Add `captcha` to your list of dependencies in `mix.exs`:
+
+ ```elixir
+ def deps do
+ [{:captcha, "~> 0.1.0"}]
+ end
+ ```
+
+ 2. Ensure `captcha` is started before your application:
+
+ ```elixir
+ def application do
+ [applications: [:captcha]]
+ end
+ ```
+## Usage
+
+```elixir
+case Captcha.get() do
+ {:ok, text, img_binary } ->
+ # save text in session, then send img to client
+ {:timeout} ->
+ # log some error
+end
+```

+# This configuration is loaded before any dependency and is restricted

+# 3rd-party users, it should be done in your "mix.exs" file.
+
+# You can configure for your application as:
+#
+# config :captcha, key: :value
+#
+# And access this configuration in your application as:
+#
+# Application.get_env(:captcha, :key)
+#
+# Or configure a 3rd-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).
