+# SlideDeck AI
+
+We spend a lot of time on creating the slides and organizing our thoughts for any presentation. 
+With SlideDeck AI, co-create slide decks on any topic with Generative Artificial Intelligence.
+Describe your topic and let SlideDeck AI generate a PowerPoint slide deck for you—it's as simple as that!
+
+
+# Process
+
+SlideDeck AI works in the following way:
+
+1. Given a topic description, it uses Llama 2 to generate the outline/contents of the slides.
+2. Next, it uses GPT 3.5 to convert the output from the previous step into JSON.
+3. Subsequently, it uses the `python-pptx` library to generate the slides, 
+based on the JSON data from the previous step. 
+Here, a user can choose from a set of three pre-defined presentation templates.
+4. In addition, it uses Metaphor to fetch Web pages related to the topic.
+5. Finally, it uses Stable Diffusion 2 to generate an image, based on the title and each slide heading.
+
+
+# Local Development
+
+SlideDeck AI uses the Clarifai API of LangChain to realize the first two steps. 
+It also sends a Web request to Clarifai for the final step.
+To run this project by yourself, you need to provide the `CLARIFAI_PAT` and `METAPHOR_API_KEY` API keys,
+for example, in a `.env` file.
