+    Welcome to the **MTG Draft Assistant**!  
+    This tool helps you evaluate booster packs and draft the best cards.
+
+    ### Steps
+    1. **Choose your set** from the sidebar.
+    2. **Add cards** to your pack using the search bar on the right.
+    3. The model will score the cards and suggest the best pick.
+    4. Click **Pick** to move a card from your pack to your deck.
+    5. Repeat until your deck is complete.
+    
+    ### Important Notes
+    The model uses data from 17Lands to score cards based drafts from other players.
+    Although it is able to make predictions for all cards, data for the most recent set is sometimes
+    not available, harming the model's performance.
+    
+    Currently, the model **only** uses how cards are picked, not how they perform in games.
+    This leads to some cards being evaluated differently, if players pick them highly.
+    For example, we find that the current model has a bias towards Rares and Mythics, which look splashy.
+    As the next step, we will filter data based on player and draft performance.
+    
+    We currently also do not support special guest cards, although these will be added soon.
+
+
+    ### Tips
+    - Hover over a score bar to see the exact value.
