+# serde
+
+[Serde](https://serde.rs/) is **rust** create used to _serialize_ and _deserialize_ stuff.
+
+For example, this can be used to deserialize toml into a dedicated struct.
+
+
+## Example, with toml
+
+Here is how serde after version 1.0 (included) should be used with serialize/deserialize mechanisms.
+
+**Be careful, there is breaaking changes before version 1.0 and you can find confusing docs.**
+
+### `main.rs` file
+
+```rust
+// crates
+extern crate toml;
+extern crate serde;
+
+// uses
+use serde::Deserialize;
+
+#[derive(Deserialize)]
+struct Config {
+    name: String,
+    url: String,
+}
+
+fn main() {
+    let content = r#"name = "example"
+url = "https://example.com""#;
+
+    let conf: Config = toml::from_str(content).unwrap();
+
+    println!("name: {}, url: {}", conf.name, conf.url)
+
+}
+```
+
+### `Cargo.toml` file
+
+```toml
+[package]
+name = "safiste"
+version = "0.1.0"
+authors = ["El Famoso Safiste"]
+edition = "2018"
+
+# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
+
+[dependencies]
+serde = { version = "1.0.94", features = ["derive"] }
+toml = "0.5.1"
+```
+
+### Output
+
+```txt
+name: example, url: https://example.com
+```
