 # hcler
+
 Encode arbitrary Go types to Hashicorp's HCL format.
+
+## Usage
+
+## Common types
+
+`hcler.Encode()` can be used with most common types.
+
+## Custom types
+
+In order to support custom types, hcler provides the `hcler.Encoder` interface, similar to `json.Marshaler` & co.
+The interface only requires the `EncodeHCL() (string, error)` method.
+
