+# File Linked - controlling objects linked directly to a file
+
+This library provides a wrapper around objects and ties the data to a file. It uses serde and bincode currently for serializing and deserializing the files.
+
+## Examples
+```rust
+use file_linked::*;
+use serde::{Deserialize, Serialize};
+use std::fmt;
+use std::string::ToString;
+use std::path::PathBuf;
+
+#[derive(Deserialize, Serialize)]
+struct Test {
+    pub a: u32,
+    pub b: String,
+    pub c: f64
+}
+
+let test = Test {
+    a: 1,
+    b: String::from("two"),
+    c: 3.0
+};
+
+let file_path = PathBuf::from("./file");
+
+// Object is consumed and can only be interacted with through the FileLinked object
+let mut linked_test = FileLinked::new(test, &file_path)?;
+
+// You can obtain a readonly reference of the underlying data
+assert_eq!(linked_test.readonly().b, String::from("two"));
+
+// Whenever a mutable operation is performed, the changed data is rewritten to the file
+linked_test.mutate(|x| x.a += 1)?;
+assert_eq!(linked_test.readonly().a, 2);
+
+drop(linked_test);
+
+// You can also initialize an object from a file
+let from_file = FileLinked::<Test>::from_file(&file_path)?;
+
+assert_eq!(from_file.readonly().a, 2);
+assert_eq!(from_file.readonly().b, String::from("two"));
+assert_eq!(from_file.readonly().c, 3.0);
+```
+
+This library is still in development and missing some features and so may not be stable:
+- Currently after any mutable operations the FileLinked object will rewrite the entire file
+- Custom selection of serializers is not implemented, the serializer used is just bincode as of now
