+# Welcome to the Tutorial
+
+To get started, follow these steps:
+
+1. **Open a Terminal in VS Code**
+    Go to `Terminal` > `New Terminal` in the VS Code menu. The shortcut is ``Ctrl + ` ``
+
+2. **Execute the Launch Command**
+    
+    Type the following command into the terminal and press Enter:
+    ```bash
+    roslaunch learn_environment tutorial_gazebo.launch
+    ```
+
+3. **Begin with the Tasks**
+    - After running the command, the task files for the tutorial will be copied into this folder.
+    - All tasks are Jupyter Notebooks. Some code is already provided in the notebook; your task is to replace the `throw notImplementedError()` with your own code.
+    - **IMPORTANT**: Do not execute these notebooks directly from VS Code. This may result in unwanted behavior and won't trigger the evaluation. Use the `start` button in the plugin.
+
+Familiarize yourself with RViz and start working on the tasks at your own pace!
