 ### example
 
 ```rust
-#[derive(Config, Default, Serialize, Deserialize)]
-#[filename = "config"] // ~/.config/appconfig/config.toml (XDG spec)
-#[extension = "toml"]  // possible values: yaml, toml, json
+// derive the `Configure` trait, and specify the
+// `config_file` attribute
+#[derive(Configure, Default, Serialize, Deserialize)]
+#[config_file = "config.toml"]
 struct AppConfig {
-    version: u8,
-    path: String,
+    -- snip --
 }
 
+// `Configure` exposes `load` and `store`
 fn main() {
     let mut config = AppConfig::load().unwrap();
-    config.version = 3;
+    config.version = 2;
     config.path = "/home/np".to_string();
     config.store();
 }
 ```
+
+You can specify a path to be used, unless you want to stick
+with the defaults:
+
+```rust
+// load from and store in user's home directory
+#[config_file = "~/config.toml"]
+```
+
+`fondant` supports `yaml`, `toml` and `json`, defaults to
+`toml`:
+
+```rust
+#[config_file = "config.toml"]
+#[config_file = "my_app_config.yaml"]
+#[config_file = "~/.app.conf.json"]
+```
