+ℹ️ **Note for production/docker container:**  
+`TOKENIZER_FOLDER` and `MODEL_FOLDER` are **only required for local development**.  
 
+When running the application in a **Docker container**, these variables are already set in the `Dockerfile` and do not need to be defined in your `.env` file.

+
+## 📥 NLTK Setup for Development
+
+If you are running the application in development mode for the first time, you need to manually download the NLTK resource required for sentence tokenization.
+
+### Run the following inside your virtual environment:
+```ini
+import nltk
+nltk.download('punkt_tab')
+```
+
+This will download the necessary model and store it on your local machine under:
+
+```
+~/nltk_data
