 - **10x Faster on Insert/Query Speeds**: Through the innovative design on storage, on a single-core machine, over 20K requests can be processed, millions of data points can be ingested, and over 10 million data points can be retrieved in a second. It is 10 times faster than other databases.
 
-- **1/5 Hardware/Cloud Service Costs**: Compared with typical big data solutions, less than 1/5 of computing resources are required. Via column-based storage and tuned compression algorithms for different data types, less than 1/10 of storage space is needed.

 - **Full Stack for Time-Series Data**: By integrating a database with message queuing, caching, and stream computing features together, it is no longer necessary to integrate Kafka/Redis/HBase/Spark or other software. It makes the system architecture much simpler and more robust..
 
-- **Powerful Data Analysis**: Whether it is 10 years or one minute ago, data can be queried just by specifying the time range. Data can be aggregated over time, multiple time streams or both. Ad Hoc queries or analyses can be executed via TDengine shell, Python, R or Matlab.

+# TDengine Node.js connector
+This is the Node.js library that lets you connect to [TDengine](https://www.github.com/taosdata/tdengine).
+
+## Installation
+
+To get started, just type in the following to install the connector through [npm](https://www.npmjs.com/)
+
+```cmd
+npm install td-connector
+```
+
+To interact with TDengine, we make use of the [node-gyp[(https://github.com/nodejs/node-gyp)] library. To install, you will need to install the following depending on platform (the following instructions are quoted from node-gyp)
+
+### On Unix
+
+- `python` (`v2.7` recommended, `v3.x.x` is **not** supported)
+- `make`
+- A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)
+
+### On macOS
+
+- `python` (`v2.7` recommended, `v3.x.x` is **not** supported) (already installed on macOS)
+
+- Xcode
+
+  - You also need to install the 
+
+    ```
+    Command Line Tools
+    ```
+
+     via Xcode. You can find this under the menu 
+
+    ```
+    Xcode -> Preferences -> Locations
+    ```
+
+     (or by running 
+
+    ```
+    xcode-select --install
+    ```
+
+     in your Terminal) 
+
+    - This step will install `gcc` and the related toolchain containing `make`
+
+### On Windows
+
+#### Option 1
+
+Install all the required tools and configurations using Microsoft's [windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) using `npm install --global --production windows-build-tools` from an elevated PowerShell or CMD.exe (run as Administrator).
+
+#### Option 2
+
+Install tools and configuration manually:
+
+- Install Visual C++ Build Environment: [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools) (using "Visual C++ build tools" workload) or [Visual Studio 2017 Community](https://visualstudio.microsoft.com/pl/thank-you-downloading-visual-studio/?sku=Community) (using the "Desktop development with C++" workload)
+- Install [Python 2.7](https://www.python.org/downloads/) (`v3.x.x` is not supported), and run `npm config set python python2.7` (or see below for further instructions on specifying the proper Python version and path.)
+- Launch cmd, `npm config set msvs_version 2017`
+
+If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.
+
+To target native ARM64 Node.js on Windows 10 on ARM, add the  components "Visual C++ compilers and libraries for ARM64" and "Visual  C++ ATL for ARM64".
+
+## Usage
+
+To use the connector, first request the library ```td-connector```. Running the function ```taos.connect``` with the connection options passed in as an object will return a TDengine connection object. A cursor needs to be intialized in order to interact with TDengine from node.
+
+```javascript
+const taos = require('td-connector');
+var conn = taos.connect({host:"127.0.0.1", user:"root", password:"taosdata", config:"/etc/taos",port:0})
+var c1 = conn.cursor(); // Initializing a new cursor
+```
+
+We can now start executing queries through the ```cursor.execute``` function.
+
+```javascript
+c1.execute('show databases;')
+```
+
+We can get the results of the queries by doing the following
+
+```javascript
+var data = c1.fetchall();
+console.log(c1.fieldNames); // Returns the names of the columns/fields
+console.log(data); // Logs all the data from the query as an array of arrays, each of which represents a row and data[row_number] is sorted in order of the fields
+```
+
+## Example
+
+The following is an example use of the connector showing how to make a table with weather data, insert random data, and then retrieve it.
+
+```javascript
+// Get the td-connector package
+const taos = require('td-connector');
+
+/* We will connect to TDengine by passing an object comprised of connection options to taos.connect and store the
+ * connection to the variable conn
+ */
+/*
+ * Connection Options
+ * host: the host to connect to
+ * user: the use to login as
+ * password: the password for the above user to login
+ * config: the location of the taos.cfg file, by default it is in /etc/taos
+ * port: the port we connect through
+ */
+var conn = taos.connect({host:"127.0.0.1", user:"root", password:"taosdata", config:"/etc/taos",port:0});
+
+// Initialize our TDengineCursor, which we use to interact with TDengine
+var c1 = conn.cursor();
+
+// c1.execute(query) will execute the query
+// Let's create a database named db
+try {
+  c1.execute('create database db;');
+}
+catch(err) {
+  conn.close();
+  throw err;
+}
+
+// Now we will use database db
+try {
+  c1.execute('use db;');
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// Let's create a table called weather
+// which stores some weather data like humidity, AQI (air quality index), temperature, and some notes as text
+try {
+  c1.execute('create table if not exists weather (ts timestamp, humidity smallint, aqi int, temperature float, notes binary(30));');
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// Let's get the description of the table weather
+try {
+  c1.execute('describe db.weather');
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// To get results, we run the function c1.fetchall()
+// It only returns the query results as an array of result rows, but also stores the latest results in c1.data
+try {
+  var tableDesc = c1.fetchall(); // The description variable here is equal to c1.data;
+  console.log(tableDesc);
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// Let's try to insert some random generated data to test with
+
+let stime = new Date();
+let interval = 1000;
+
+// Timestamps must be in the form of "YYYY-MM-DD HH:MM:SS.MMM" if they are in milliseconds
+//                                   "YYYY-MM-DD HH:MM:SS.MMMMMM" if they are in microseconds
+// Thus, we create the following function to convert a javascript Date object to the correct formatting
+function convertDateToTS(date) {
+  let tsArr = date.toISOString().split("T")
+  return "\"" + tsArr[0] + " " + tsArr[1].substring(0, tsArr[1].length-1) + "\"";
+}
+
+try {
+  for (let i = 0; i < 10000; i++) {
+    stime.setMilliseconds(stime.getMilliseconds() + interval);
+    let insertData = [convertDateToTS(stime),
+                      parseInt(Math.random()*100),
+                      parseInt(Math.random()*300),
+                      parseFloat(Math.random()*10 + 30),
+                      "\"random note!\""];
+    c1.execute('insert into db.weather values(' + insertData.join(',') + ' );');
+  }
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// Now let's look at our newly inserted data
+var retrievedData;
+try {
+  c1.execute('select * from db.weather;')
+  retrievedData = c1.fetchall();
+
+  // c1.fieldNames stores the names of each column retrieved
+  console.log(c1.fieldNames);
+  console.log(retrievedData);
+  // timestamps retrieved are always JS Date Objects
+  // Numbers are numbers, big ints are big ints, and strings are strings
+}
+catch (err) {
+  conn.close();
+  throw err;
+}
+
+// Let's try running some basic functions
+try {
+  c1.execute('select count(*), avg(temperature), max(temperature), min(temperature), stddev(temperature) from db.weather;')
+  c1.fetchall();
+  console.log(c1.fieldNames);
+  console.log(c1.data);
+}
+catch(err) {
