+
+Zero-boilerplate configuration management.
+
+Focus on storing the right data, instead of worrying about how or where to store it.
+
+```rust
+use serde_derive::{Serialize, Deserialize};
+
+#[derive(Default, Debug, Serialize, Deserialize)]
+struct MyConfig {
+    version: u8,
+    api_key: String,
+}
+
+fn main() -> Result<(), ::std::io::Error> {
+    let cfg: MyConfig = confy::load("my-app-name")?;
+    dbg!(cfg);
+    Ok(())
+}
+```
+
+## Using yaml
+Enabling the `yaml_conf` feature while disabling the default `toml_conf`
+feature causes confy to use a YAML config file instead of TOML.
+
+```
+[dependencies.confy]
+features = ["yaml_conf"]
+default-features = false
+```
+
+## Breakings changes
+Starting with version 0.4.0 the configuration file are stored in the expected place for your system. See the [`directories`] crates for more information.
+Before version 0.4.0, the configuration file was written in the current directory.
