 ## Getting Started
 
-This section describes how to set up a development environment. Everything you
-need is contained in a [Docker image](https://registry.hub.docker.com/u/wappalyzer/dev/)
-which is managed by Vagrant.
-
-Running this environment is optional but recommended as it provides some helpful tools.
-
-First, install [Docker](https://www.docker.com/) and [Vagrant](https://www.vagrantup.com/)
-on your system.
-
-Clone the Wappalyzer repository and open the newly created directory in a
-terminal. Run `vagrant up` to start the environment.
-
-Run `vagrant ssh` to access the environment and read usage instructions.
+Install [Docker](https://www.docker.com/) on your system first.
 
 ```shell
-$ git clone https://github.com/AliasIO/Wappalyzer.git wappalyzer
-$ cd wappalyzer
-$ vagrant up
-$ vagrant ssh
+$ git clone https://github.com/AliasIO/Wappalyzer.git
+$ cd Wappalyzer
+$ ./run links
 ```
 
-To stop the environment, run `vagrant halt`.
+The	`links` command creates symlinks for files that shared between the various
+drivers (i.e. different platforms). If your file system does not support
+symlinks, you need to manually copy these files (see `bin/links`).
 
-If a new Docker image becomes available, rebuild the environment with
-`vagrant destroy -y && vagrant up`.
+Please run `./run validate` before submitting a pull request.
