+## Install
+`npm install sync-queue`
+
+## Usage
+
+```.js
+var Queue = require('sync-queue')
+var queue = new Queue();
+
+queue.place(function one() {
+  console.log('I'm func one);
+
+  setTimeout(function() {
+    console.log("and I'm still finishing up...");
+    queue.next();
+  }, 1000);
+})
+
+queue.place(function two() {
+  console.log.bind(this, "I'm the last func.");
+  queue.next();
+});
+```
