+# Serialize ImmutableJS data
+
+### Installation
+
+```
+yarn add remotedev-serialize
+```
+
+### Usage with ImmutableJS data structures
+
+Just pass the Immutable library to our class:
+
+```js
+import Immutable from 'immutable';
+import Serialize from 'remotedev-serialize';
+const { stringify, parse } = Serialize.immutable(Immutable);
+
+const data = Immutable.fromJS({ foo: 'bar', baz: { qux: 42 } });
+const serialized = stringify(data);
+console.log(serialized);
+// {"data":{"foo":"bar","baz":{"data":{"qux":42},"__serializedType__":"ImmutableMap"}},"__serializedType__":"ImmutableMap"}
+const parsed = parse(serialized);
+console.log(Immutable.is(parsed, data));
+// true
+```
+
+See [the tests](https://github.com/reduxjs/remote-devtools/blob/master/packages/remotedev-serialize/test/immutable.spec.js) for more examples of usage.
+
+### Usage with ImmutableJS Record classes
+
+To parse a Record class back, you need to specify a reference to it:
+
+```js
+import Immutable from 'immutable';
+import Serialize from 'remotedev-serialize';
+
+const ABRecord = Immutable.Record({ a: 1, b: 2 });
+const { stringify, parse } = Serialize.immutable(Immutable, [ABRecord]);
+
+const myRecord = new ABRecord({ b: 3 });
+const serialized = stringify(myRecord);
+console.log(serialized);
+// {"data":{"a":1,"b":3},"__serializedType__":"ImmutableRecord","__serializedRef__":0}
+const parsed = parse(serialized);
+console.log(Immutable.is(parsed, myRecord));
+// true
+```
+
+### Passing custom serialization functions
+
+You can pass custom replacer and reviver functions to Serialize:
+
+```js
+import Immutable from 'immutable';
+import Serialize from 'remotedev-serialize';
+
+function customReplacer(key, value, defaultReplacer) {
+  if (value === 1) {
+    return { data: 'one', __serializedType__: 'number' };
+  }
+  return defaultReplacer(key, value);
+}
+
+function customReviver(key, value, defaultReviver) {
+  if (
+    typeof value === 'object' &&
+    value.__serializedType__ === 'number' &&
+    value.data === 'one'
+  ) {
+    return 1;
+  }
+  return defaultReviver(key, value);
+}
+
+const { stringify, parse } = Serialize.immutable(
+  Immutable,
+  null,
+  customReplacer,
+  customReviver
+);
+
+const map = Immutable.Map({ a: 1, b: 2 });
+const serialized = stringify(map);
+console.log(serialized);
+// {"data":{"a":{"data":"one","__serializedType__":"number"},"b":2},"__serializedType__":"ImmutableMap"}
+const parsed = parse(serialized);
+console.log(Immutable.is(parsed, map));
+// true
+```
