# Marimo Development Create reactive Python notebooks with marimo's interactive programming environment. ## Core Workflow 1. **Start with fundamentals**: Read `references/core-concepts.md` - contains marimo's cell structure, reactivity model, UI elements, and essential examples 2. **Use recipes for common tasks**: Check `references/recipes.md` for code snippets 3. **Refer to API docs**: Navigate `references/api/` for specific function details 4. **Troubleshoot issues**: See `references/faq.md` and `references/troubleshooting.md` ## Key Marimo Concepts ### Cell Structure Every marimo cell follows this structure: ```python @app.cell def _(): # Your code here return ``` When editing cells, only modify the code inside the function - marimo handles parameters and returns automatically. ### Reactivity Rules 1. **Automatic execution**: When a variable changes, cells using it automatically re-run 2. **No redeclaration**: Variables cannot be redeclared across cells 3. **DAG structure**: Cells form a directed acyclic graph (no circular dependencies) 4. **Last expression displays**: The final expression in a cell is automatically shown 5. **UI reactivity**: UI element values accessed via `.value` trigger automatic updates 6. **Local variables**: Variables prefixed with `_` (e.g., `_temp`) are local to the cell ### Import Pattern Always import marimo in the first cell: ```python @app.cell def _(): import marimo as mo # other imports return ``` ## Common
