-OpenCensus Node.js is an implementation of OpenCensus, a toolkit for collecting application performance and behavior monitoring data. Right now OpenCensus for Node.js supports custom tracing and automatic tracing for http and mongodb.
+OpenCensus for Node.js is an implementation of OpenCensus, a toolkit for collecting application performance and behavior monitoring data. 
 
 The library is in alpha stage and the API is subject to change.
 
 Please join [gitter](https://gitter.im/census-instrumentation/Lobby) for help or feedback on this project.
 
-Note: This code was tested on the following Node versions:
-- v6.10.0 (for console exporter only)
-- v9.8.0 (for Stackdriver and Zipkin exporters)

-## OpenCensus Setup
-
-1. Clone the OpenCensus Node repository < https://github.com/census-instrumentation/opencensus-node.git>
-```bash
-git clone https://github.com/census-instrumentation/opencensus-node.git
-```
-
-**TODO Ver com Fábio se o usuário terá que compilar**
-
-2. Switch to branch `dev` with:
-```bash
-git checkout dev
-```
-
-3. Navigate to the OpenCensus Node project folder and install the dependencies with:
-```bash
-cd opencensus-node
-npm install
-```
-
-4. Compile the TypeScript code into JavaScript with:
-```
-node_modules/.bin/tsc
-```
-
-___
-
-## Instrumenting an Application
-
-Navigate to your application folder. Inside it's `node_modules` folder, create a directory named `@opencensus`:
-```
-cd node_modules
-mkdir @opencensus
-```
-
-Navigate to your new `@opencensus` folder and create a symlink to OpenCensus Node package with:
-```bash
-cd @opencensus
-ln -s <path-to-opencensus-dir>/packages/opencensus-nodejs/ opencensus-nodejs
-```
-
-### Using Stackdriver Exporter
-
-To use Stackdriver as your exporter, make sure you have enabled [Stackdriver Tracing](https://cloud.google.com/trace/docs/quickstart) on Google Cloud Platform. Enable your [Application Default Credentials](https://cloud.google.com/docs/authentication/getting-started) for authentication with:
-```bash
-export GOOGLE_APPLICATION_CREDENTIALS=path/to/your/credential.json
-```
-
-Add the OpenCensus Stackdriver Exporter package to your project's `node_modules/@opencensus` folder with:
-```
-cd node_modules/@opencensus
-ln -s <path-to-opencensus-dir>/packages/opencensus-exporter-stackdriver/ opencensus-exporter-stackdriver
-```
-
-Finally, on top of your application, add the following lines of code:
-```javascript
-var tracing = require('@opencensus/opencensus-nodejs');
-var stackdriver = require('@opencensus/opencensus-exporter-stackdriver');
-
-// Add your project id to the Stackdriver options
-var options = new stackdriver.StackdriverOptions('your-project-id');
-var exporter = new stackdriver.Stackdriver(options);
-
-tracing.registerExporter(exporter).start();
-```
-
-### Using Zipkin Exporter
-
-To use Zipkin as your exporter, first, download from any of the three available options on [Quickstart](https://zipkin.io/pages/quickstart.html): through Docker, on Java or manually compiling the source code. Tests were executed running Zipkin with Java, through the following commands on terminal:
-```bash
-wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec'
-java -jar zipkin.jar
-```
-
-Add the OpenCensus Zipkin Exporter package to your project's `node_modules/@opencensus` folder with:
-```
-cd node_modules/@opencensus
-ln -s <path-to-opencensus-dir>/packages/opencensus-exporter-zipkin/ opencensus-exporter-zipkin
-```
-
-Finally, on top of your application, add the following lines of code:
-```javascript
-var tracing = require('@opencensus/opencensus-nodejs');
-var zipkin = require('@opencensus/opencensus-exporter-zipkin');
-
-// Add your zipkin url and application name to the Zipkin options
-var options = new zipkin.ZipkinOptions("your-zipkin-url", "your-application-name")
-var exporter = new zipkin.Zipkin(options);
-
-tracing.registerExporter(exporter).start();
-```
