+# Kaleido
+
+Kaleido is a cross-platform library for generating static images for [Plotly][plotly]'s visualization library.
+After installing it, you can use `fig.write_image("filename.png")` to save a plot to a file.
+
+<div align="center">
+  <a href="https://dash.plotly.com/project-maintenance">
+    <img src="https://dash.plotly.com/assets/images/maintained-by-plotly.png" width="400px" alt="Maintained by Plotly">
+  </a>
+</div>
+
+## How It Works
+
+The original version of kaleido included a custom build of the Chrome web browser,
+which made it very large (hundreds of megabytes) and proved very difficult to maintain.
+In contrast,
+this version depends on [choreographer][choreographer],
+a lightweight library that enables remote control of browsers from Python.
+When you ask kaleido to create an image,
+it uses choreographer to run a headless instance of Chrome to render and save your figure.
+Please see choreographer's documentation for details.
+
+> The new version of kaleido is a work on progress; we would be grateful for help testing it and improving it.
+> If you find a bug, please report it in [our GitHub repository][repo],
+> and please include a minimal reproducible example if you can.
+>
+> It would also be very helpful to run the script `src/py/tests/manual.py`
+> and attach its zipped output to your bug report.
+> This will give us detailed information about the precise versions of software you are using
+> and the platform you are running on,
+> which will help us track down problems more quickly.
+
+## Installation
+
+You can install kaleido from [PyPI][pypi] using pip:
+
+```
+$ pip install kaleido
+```
+
+## Use
+
+Versions 4.9 and above of the Plotly Python library will automatically use kaleido for static image export when kaleido is installed.
+For example:
+
+```python
+import plotly.express as px
+fig = px.scatter(px.data.iris(), x="sepal_length", y="sepal_width", color="species")
+fig.write_image("figure.png", engine="kaleido")
+```
+
+See the [Plotly static image export documentation][plotly-export] for more information.
