+<h1>Getting started with CARLA</h1>
+
+![Welcome to CARLA](img/welcome.png)
+
+Welcome to CARLA! This tutorial provides the basic steps for getting started
+using CARLA.
+
+<!-- Latest release button -->
+<p align="middle"><a href="https://github.com/carla-simulator/carla/releases/latest" target="_blank" class="btn btn-neutral" title="Go to the latest CARLA release"><span class="icon icon-github"></span> Get the latest release</a></p>
+
+Download the latest release from our GitHub page and extract all the contents of
+the package in a folder of your choice.
+
+The release package contains the following
+
+  * The CARLA simulator.
+  * The "carla" Python module.
+  * Some Python client examples.
+
+For now we will focus on the simulator only. The simulator can be run in two
+different modes
+
+  * **Server mode:** The simulator is controlled by a client application that
+    collects data and sends driving instructions. In this mode the simulator
+    hangs until a client starts a connection.
+  * **Standalone mode:** The simulator starts in sort of _video-game mode_ in
+    which you can control the vehicle with the keyboard.
+
+In the next item in this tutorial we will run the **standalone mode** to take a
+first look into CARLA.

+<h1>Running the CARLA simulator in standalone mode</h1>
+
+Inside the downloaded package you should find a shell script called
+`CarlaUE4.sh`, this script launches the CARLA simulator.
+
+!!! tip
+    Although this tutorial focuses on Linux, all the commands work as well in
+    Windows. Just replace all the occurrences of `./CarlaUE4.sh` by
+    `CarlaUE4.exe`.
+
+Run this script without arguments to launch CARLA simulator in standalone mode
+with default settings
+
+    $ ./CarlaUE4.sh
+
+This launches the simulator window in full-screen, and you should be able
+now to drive around the city using the WASD keys, and Q for toggling reverse
+gear. See ["Keyboard input"](simulator_keyboard_input.md) for the complete list
+of key-bindings.
+
+![Simulator window](img/simulator_window.png)
+
+We have currently two scenarios available, _Town01_ and _Town02_. You may want
+now to take a look at _Town02_, you can do so by running the script with
+
+    $ ./CarlaUE4.sh /Game/Maps/Town02
+
+All the parameters like number of other vehicles, pedestrians, and weather
+conditions can be controlled when launching the simulation. These parameters are
+set in a _"CarlaSettings.ini"_ file that is passed to the simulator either as a
+command-line parameter or when connecting with a Python client. This file
+controls all the variable of the CARLA simulator, from server settings to
+attaching sensors to the vehicle, we will cover all these later, for now we will
+just change some visible aspect in the standalone mode. For a detailed
+description of how the settings work, see ["CARLA Settings"](carla_settings.md)
+section.
+
+Open the file _"Example.CarlaSettings.ini"_ in a text editor, search for the
+following keys and modify their values
+
+```ini
+NumberOfVehicles=60
+NumberOfPedestrians=60
+WeatherId=3
+```
+
+Now run the simulator passing the settings file as argument with
+
+    $ ./CarlaUE4.sh -carla-settings=Example.CarlaSettings.ini
+
+Now the simulation should have more vehicles and pedestrians, and a
+different weather preset.
+
+!!! tip
+    You can launch the simulator in windowed mode by using the argument
+    `-windowed`, and control the window size with `-ResX=N` and `-ResY=N`.
+
+In the next item of this tutorial we show how to control the simulator with a
+Python client.
