+<h2>REST API</h2>
+<p>
+This is early days for healtchecks.io REST API. For now, there's just
+one API call: for creating a new check.
+</p>
+
+<h2 class="rule">Authentication</h2>
+<p>Your requests to healtchecks.io REST API must authenticate using an
+API key. By default, an user account on healthchecks.io doesn't have
+an API key. You can create one in the <a href="{% url 'hc-profile' %}">Settings</a> page.
+</p>
+
+<p>
+The API uses a simple authentication scheme: the API key should be
+included in the request body (a JSON document) along other fields.
+</p>
+
+<h2 class="rule">API Requests</h2>
+
+<p>
+For POST requests, the healthchecks.io API expects request body to be
+a JSON document (<em>not</em> a <code>mulitpart/form-data</code> encoded
+form data).
+</p>
+
+<h2 class="rule">API Responses</h2>
+
+<p>
+healthchecks.io uses HTTP status codes wherever possible.
+In general, 2xx class indicates success, 4xx indicates an client error,
+and 5xx indicates a server error.
+</p>
+
+<p>
+The response may contain a JSON document with additional data.
