-A collection class with a batch feature with commit/rollback/replay
+
+> Generic in-memory collection with events
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/collection):
+
+```
+> npm install --save collection
+```
+
+## Usage
+
+```javascript
+var Collection = require('collection')
+```
+
+### Creation
+
+```javascript
+// Creates a new collection.
+var col = new Collection()
+```
+
+### Manipulation
+
+**Inserting a new entry**
+
+```javascript
+col.add('foo', true)
+```
+
+**Updating an existing entry**
+
+```javascript
+col.update('foo', false)
+```
+
+**Inserting or updating an entry**
+
+```javascript
+col.set('bar', true)
+```
+
+**Notifying an external update**
+
+> If an entry is an object, it can be updated directly without using
+> the `set`/`update` methods.
+>
+> To make sure the collection stay in sync and the correct events are
+> sent, the `touch` method can be used to notify the change.
+
+```javascript
+var baz = {}
+
+col.add('baz', baz)
+
+baz.prop = true
+col.touch('baz')
+```
+
+> Because this is a much used pattern, `touch` returns the entry to
+> allow its direct modification.
+
+```javascript
+col.touch('baz').prop = false
+```
+
+**Removing an existing entry**
+
+```javascript
+col.unset('bar')
+```
+
+**Removing all entries**
+
+```javascript
+col.clear()
+```
+
+### Query
+
+**Checking the existence of an entry**
+
+```javascript
+var hasBar = col.has('bar')
+```
+
+**Getting an existing entry**
+
+```javascript
+var foo = col.get('foo')
+
+// The second parameter can be used to specify a fallback in case the
+// entry does not exist.
+var bar = col.get('bar', 6.28)
+```
+
+**Getting the number of entries**
+
+```javascript
+var size = col.size
+```
+
+### Events
+
+> The events are emitted asynchronously (at the next turn/tick of the
+> event loop) and are deduplicated which means, for instance, that an
+> addition followed by an update will result only in a single
+> addition.
+
+**New entries**
+
+```javascript
+col.on('add', (added) => {
+  forEach(added, (value, key) => {
+    console.log('+ %s: %j', key, value)
+  })
+})
+```
+
+**Updated entries**
+
+```javascript
+col.on('update', (updated) => {
+  forEach(updated, (value, key) => {
+    console.log('- %s: %j', key, value)
+  })
+})
+```
+
+**Removed entries**
+
+```javascript
+col.on('remove', (removed) => {
+  // For consistency, `removed` is also a map but contrary to `ædded`
+  // and `updated`, the values associated to the keys are not
+  // significant since the entries have already be removed.
+
+  forEach(removed, (value, key) => {
+    console.log('± %s', key)
+  })
+})
+```
+
+## Development
+
+### Installing dependencies
+
+```
+> npm install
+```
+
+### Compilation
+
+The sources files are watched and automatically recompiled on changes.
+
+```
+> npm run dev
+```
+
+### Tests
+
+```
+> npm run test-dev
+```
