+# YouTube Shorts Automation with Streamlit
+
+## Overview
+This notebook automates the creation of YouTube Shorts by leveraging trending content generated via the Hugging Face API, fetching stock videos from the Pexels API, and applying color correction based on a reference image. The final videos are trimmed to 3 seconds and saved in a specified directory. The Streamlit app facilitates interaction with this system.
+
+## Setup
+1. **Install Required Libraries**
+    - Install required Python packages including `requests`, `Pillow`, `moviepy`, `opencv-python`, `python-dotenv`, and `streamlit`.
+
+2. **Import Necessary Modules**
+    - Import modules from `fetch_content`, `fetch_videos`, `process_videos`, and `color_correction`.
+
+3. **Configure Environment Variables**
+    - Ensure the `.env` file contains your API keys for Hugging Face and Pexels.
+
+## Steps
+
+### 1. Fetch Trending Content
+- Use the `fetch_content.py` script to interact with the Hugging Face API.
+- Generate trending content and extract relevant keywords.
+
+```python
+!python3 scripts/fetch_content.py
+```
+
+### 2. Fetch Stock Videos
+- Use the `fetch_videos.py` script to fetch videos from Pexels based on the keywords.
+- Ensure that no video exceeds 3 seconds. If necessary, trim longer videos.
+
+```python
+!python3 scripts/fetch_videos.py
+```
+
+### 3. Process Videos
+- Use the `process_videos.py` script to trim videos to 3 seconds.
+- Apply color correction based on the `reference/` directory’s `reference_image.jpg`.
+
+```python
+!python3 scripts/process_videos.py
+```
+
+### 4. Save Final Videos
+- Save all processed videos in the `videos/final_videos/` directory.
+
+```python
+!python3 scripts/save_videos.py
+```
+
+### 5. Run Streamlit App
+- Start the Streamlit app to interact with the entire process.
+
+```python
+!streamlit run streamlit_app/app.py
+```
+
+## Notes
+- Ensure API keys are correctly set in the `.env` file.
+- Check the `requirements.txt` for necessary package installations.
+
+## Conclusion
+Run each script in the specified order to automate the creation of engaging YouTube Shorts content. Use the Streamlit app to interact with the process and view results in the `videos/final_videos/` directory.
