+# PEG.js Test Suites
+
+This directory contains various test suites and scripts to ensure PEG.js works correctly.
+
+* [Spec Suite](spec): Runs various test's that ensure PEG.js and it's generated parsers are working as intended. All tests should always pass on all supported platforms.
+* [Benchmark Suite](benchmark): It measures speed of the parsers generated by PEG.js on various inputs. Its main goal is to provide data for code generator optimizations.
+* [Impact Script](impact): Measures impact of a Git commit (or multiple commits) on generated parsers speed and size.
+
+## Download and Install
+
+To run the PEG.js test suites you most download the and install the module via the git repository:
+
+  1. Make sure you have Node.js and Git installed.
+
+  2. Download via Git and change the currently working directory:
+
+     ```console
+     $ git clone https://github.com/pegjs/pegjs.git
+     $ cd pegjs
+     ```
+
+  3. Install all dependencies, including the development dependencies:
+
+     ```console
+     $ npm install
+     ```
+
+  4. Install Gulp globally:
+
+     ```console
+     $ npm install gulp -g
+     ```
+
+  5. Processed...

+     * [Running in Node.js](#running-in-nodejs)
+     * [Running in the Browser](#running-in-the-browser)
+
+## Running in Node.js
+
+The commands below need to be executed via the console from the PEG.js root directory (one level up from this one), after which they will output their results (if any).
+
+  * Execute source code linting:
+
+     ```console
+     $ gulp lint
+     ```
+
+  * Execute the spec test suite:
+
+     ```console
+     $ gulp test
+     ```
+
+  * Execute the benchmark suite:
+
+     ```console
+     $ gulp benchmark
+     ```
+
+  * Execute the impact suite:
+
+     ```console
+     $ node test/impact
+     ```
+
+## Running in the Browser
+
+  1. Serve the test suites using a web server:
+
+     ```console
+     $ node test/server/run
+     ```
+
+  2. Point your browser to the [test suite](http://localhost:8000/)
