 A **Node** is the smallest building block of Mini LLM Flow. Each Node has three lifecycle methods:
 
 1. **`prep(shared)`**  
-   - Optionally preprocess data before calling your LLM or doing heavy computation. 
-   - Often used for tasks like reading files, chunking text, or validation.
+   - Reads and preprocesses data from the `shared` store for LLMs.
+   - Examples: query DB, read files, or serialize data into a string.
    - Returns `prep_res`, which will be passed to both `exec()` and `post()`.
