+# The interactive `pandas` REPL
+
+An interactive REPL to easily try `pandas` in the browser, powered by JupyterLite.
+
+![image](https://user-images.githubusercontent.com/591645/175000291-e8c69f6f-5f2c-48d7-817c-cff05ab2cde9.png)
+
+## Build
+
+The interactive REPL is built with the `jupyter lite` CLI.
+
+First make sure `jupyterlite` and a kernel are installed:
+
+```bash
+python -m pip install jupyterlite
+```
+
+Then in `web/interactive_terminal`, run the following command:
+
+```bash
+jupyter lite build
+```
+
+## Configuration
+
+This folder contains configuration files for the interactive terminal powered by JupyterLite:
+
+- `jupyter_lite_config.json`: build time configuration, used when building the assets with the `jupyter lite build` command
+- `jupyter-lite.json` run time configuration applied when launching the application in the browser
+
+The interactive `pandas` terminal application enables a couple of optimizations to only include the `repl` app in the generated static assets.
+
+To learn more about it, check out the JupyterLite documentation:
+
+- Optimizations: https://jupyterlite.readthedocs.io/en/latest/howto/configure/advanced/optimizations.html
+- JupyterLite schema: https://jupyterlite.readthedocs.io/en/latest/reference/schema-v0.html
+- CLI reference: https://jupyterlite.readthedocs.io/en/latest/reference/cli.html
