+# Unit 1: Introduction to Deep Reinforcement Learning
+
+In this Unit, you'll learn the foundations of Deep RL. And **you’ll train your first lander agent 🚀 to land correctly on the Moon 🌕** using Stable-Baselines3 and share it with the community.
+
+You'll then be able to **compare your agent’s results with other classmates thanks to a leaderboard** 🔥.
+
+This course is **self-paced**, you can start whenever you want.
+
+## Required time ⏱️
+The required time for this unit is, approximately:
+- 2 hours for the theory
+- 1 hour for the hands-on.
+
+## Start this Unit 🚀
+Here are the steps for this Unit:
+
+1️⃣ Sign up to our Discord Server. This is the place where you **can exchange with the community and with us, create study groups to grow each other and more** 
+
+👉🏻 [https://discord.gg/aYka4Yhff9](https://discord.gg/aYka4Yhff9).
+
+2️⃣ **Introduce yourself on Discord in #introduce-yourself Discord channel 🤗 and check on the left the Reinforcement Learning section.**
+
+- In #rl-announcements we give the last information about the course.
+- #discussions is a place to exchange.
+- #unity-ml-agents is to exchange about everything related to this library.
+- #study-groups, to create study groups with your classmates.

+
+3️⃣ 📖 Read An [Introduction to Deep Reinforcement Learning](), where you’ll learn the foundations of Deep RL. You can also watch the video version attached to the article. 👉 [ARTICLE LINK]
+
+4️⃣ 👩‍💻 Then dive on the hands-on, where **you’ll train your first lander agent 🚀 to land correctly on the Moon 🌕 using Stable-Baselines3 and share it with the community.** Thanks to a leaderboard, **you'll be able to compare your results with other classmates** and exchange the best practices to improve your agent's scores Who will win the challenge for Unit 1 🏆?
+
+The hands-on 👉
+
+The leaderboard 👉
+
+You can work directly **with the colab notebook, which allows you not to have to install everything on your machine (and it’s free)**.
+
+5️⃣ The best way to learn **is to try things on your own**. That’s why we have a challenges section in the colab where we give you some ideas on how you can go further: using another environment, using another model etc.

+
+## How to make the most of this course
+
+To make the most of the course, my advice is to:
+
+- Participate in Discord channel and join a study group.
+- Read multiple time the theory part and takes some notes
+- Don’t just do the colab. When you learn something try to change the environment, change the parameters and read the libraries documentations. Have fun 🥳
