 # Custom Components
 
-Components are third-party Python modules that extend what's possible with Streamlit.
+Custom Components are powerful extensions for Streamlit that unlock capabilities beyond the built-in widgets. They let you integrate any web technology—from advanced data visualizations to specialized input controls to complete mini-applications—directly into your Streamlit apps.
 
-## How to use a Component
+## Getting started
 
-Components are super easy to use:
+<TileContainer>
 
-1. Start by finding the Component you'd like to use. Two great resources for this are:
-   - The [Component gallery](https://streamlit.io/components)
-   - [This thread](https://discuss.streamlit.io/t/streamlit-components-community-tracker/4634),
-     by Fanilo A. from our forums.
+<RefCard href="/develop/concepts/custom-components/overview">
 
-2. Install the Component using your favorite Python package manager. This step and all following
-   steps are described in your component's instructions.
+<h4>Overview of Custom Components</h4>
 
-   For example, to use the fantastic [AgGrid
-   Component](https://github.com/PablocFonseca/streamlit-aggrid), you first install it with:
+Learn what custom components are, when to use them, and understand the differences between v1 and v2 approaches.
 
-   ```python
-   pip install streamlit-aggrid
-   ```
+</RefCard>
 
-3. In your Python code, import the Component as described in its instructions. For AgGrid, this step
-   is:
+<RefCard href="/develop/concepts/custom-components/v1">
 
-   ```python
-   from st_aggrid import AgGrid
-   ```
+<h4>Components v1</h4>
 
-4. ...now you're ready to use it! For AgGrid, that's:
+The original custom components framework. Learn how to use and build v1 components.
 
-   ```python
-   AgGrid(my_dataframe)
-   ```
