+# How it works?
+
+
+Lonboard is built on four foundational technologies: deck.gl, GeoArrow, GeoParquet, and anywidget.
+
+[deck.gl](https://deck.gl/) is a JavaScript geospatial data visualization library. Because deck.gl uses the GPU in your computer to render data, it's capable of performantly rendering very large quantities of data.
+
+[GeoArrow](https://geoarrow.org/) is a memory format for efficiently representing geospatial vector data. As a memory format, GeoArrow is not compressed and can be used directly.
+
+[GeoParquet](https://geoparquet.org/) is a file format for efficiently encoding and decoding geospatial vector data. As a file format, GeoParquet contains very efficient compression, and needs to be parsed before it can be used. [^1]
+
+[^1]: lonboard currently doesn't use "official" GeoParquet 1.0, because the 1.0 spec requires encoding geometries as Well-Known Binary (WKB) inside of the Parquet file. lonboard uses the highly-efficient GeoArrow encoding inside of GeoParquet (which may [become part of the GeoParquet spec in 1.1](https://github.com/opengeospatial/geoparquet/issues/185)). This is faster and easier to write when the writer and reader are both using GeoArrow anyways.
+
+[anywidget](https://anywidget.dev/) is a framework for building custom Jupyter widgets that makes the process much easier than before.
+
+## How is it so fast?
+
+Lonboard is so fast because it moves data from Python to JavaScript (in your browser) and then from JavaScript to your Graphics Processing Unit (GPU) more efficiently than ever before.
+
+Other Python libraries for interactive maps exist (such as [`ipyleaflet`](https://github.com/jupyter-widgets/ipyleaflet)), and even existing bindings to deck.gl exist (such as [`pydeck`](https://pypi.org/project/pydeck/)). But those libraries encode data as GeoJSON to copy from Python to the browser. GeoJSON is **extremely slow** to read and write and results in a very large data file that has to be copied to the browser.
+
+With lonboard, the _entire pipeline_ is binary. In Python, GeoPandas to GeoArrow to GeoParquet avoids a text encoding like GeoJSON and results in a compressed binary buffer that can be efficiently copied to the browser. In JavaScript, GeoParquet to GeoArrow offers efficient decoding (in WebAssembly). Then deck.gl is able to interpret the GeoArrow table _directly_ without any parsing (thanks to [`@geoarrow/deck.gl-layers`](https://github.com/geoarrow/deck.gl-layers)).
+
+The end user doesn't care about rendering _GeoJSON_, they want to render _their data_. Lonboard focuses on abstracting how to most efficiently move data so that the end user doesn't have to think about it.
