 ### Learn deeper in Our Blog 
+The HyDE approach recognizes the difficulty of zero-shot learning and encoding relevance without labeled data. Instead, it leverages the power of language models and hypothetical documents. Here’s how it works:
 
-For a deeper dive into the cutting-edge technologies of HyDE, and to access detailed technical knowledge, check out our Medium Blog.
+1. **Generating Hypothetical Documents**: When a user enters a query, HyDE instructs a language model, like GPT-3, to generate a hypothetical document. This document is designed to capture relevance patterns but may contain inaccuracies.
+2. **Unsupervised Encoding**: The generated hypothetical document is then encoded into an embedding vector using an unsupervised contrastive encoder. This vector identifies a neighborhood in the corpus embedding space, where similar real documents are retrieved based on vector similarity.
+3. **Retrieval Process**: HyDE searches for real documents in the corpus that are most similar to the encoded hypothetical document. The retrieved documents are then presented as search results.
