 # BokehJS Examples
 
-Examples of integrating bokehjs with other libraries or tooling (e.g. webpack).
+## Introduction
 
-Initially contains TypeScripts examples, with others to follow later.
+Examples using BokehJS as a standalone library without Python.
 
-Cannot be built using a release NPM package of BokehJS and changes are required which will not be
-released until BokehJS 4.0. In the meantime simple examples work using a particular Bokeh branch
-which can be checked out and built in a temporary directory and the resultant NPM package copied
-across to the root directory of this repository as follows. Note you will need `git` and `node`
-installed.
-
-```bash
-cd <directory of choice>
-git clone -b ianthomas23/13732_maybe_initialize --single-branch --depth 1 https://github.com/bokeh/bokeh.git
-cd bokeh/bokehjs
-node make build
-npm pack
-```
-
-This will produce the file `bokeh-bokehjs-3.8.0-dev.1.tgz` which should be copied to the root
-directory of the bokehjs-examples repository.
+Currently contains examples of integrating BokehJS with TypeScript frameworks and build tools,
+other possibilities to follow later.

+
+## Contents
+
+### Examples
+
+The examples are located in the top-level `typescript` directory. The following combinations of
+frameworks and build tools are included:
+
+Directory | Framework | Build tool
+--- | --- | ---
+angular_ng | [Angular](https://angular.dev/) | [ng](https://angular.dev/cli/build)
+react_vite | [React](https://react.dev/) | [Vite](https://vite.dev/)
+vanilla_rspack | None | [Rspack](https://rspack.dev/)
+vanilla_vite | None | [Vite](https://vite.dev/)
+vanilla_webpack | None | [Webpack](https://webpack.js.org/)
+vue_vite | [Vue](https://vuejs.org/) | [Vite](https://vite.dev/)
+
+Each directory contains a `README.md` that describes the steps to follow to create a simple BokehJS
+example using that combination of framework and build tool. There is also a subdirectory called
+`created` that contains the files generated by following the steps in the `README.md`.
+The easiest way to try out an example is to clone this repository, `cd` to the appropriate `created`
+directory and build the example using `npm` commands from the `package.json` in the usual manner.
+
+### Recipes
+
+Each example is created from a recipe located in the `recipes` directory. Each recipe is a
+TypeScript class that can be used to generate both a human-readable `README.md` file and a `bash`
+script that can be used to automatically create the example. See `recipes/README.md` for more
+information.
+
+### Testing
+
+All recipes are automatically recreated and tested once a week and whenever a PR is submitted to
+this repository. The code for this is contained in the `ci` directory. The `bash` scripts to create
+examples are in the `ci/typescript` directory; these can be individually run to create and build a
+single example. The `ci/tests` directory contains the [Playwright](https://playwright.dev/) test
+code and comparison images used in CI. For further details see the scripts in the `ci` directory
+and the github action workflows in `.github/workflows/test.yml`.
+
+## Limitations
+
+Currently these examples cannot be built using a release NPM package of BokehJS as changes are
+required which will not be released until BokehJS 4.0.
+In the meantime the examples work using an NPM package produced using a particular Bokeh branch
+which can be checked out and built in a temporary directory and the resultant NPM package copied
+across to the root directory of this repository as follows. Note you will need `git` and `node`
+installed.
+
+```bash
+cd <directory of choice>
+git clone -b ianthomas23/13732_maybe_initialize --single-branch --depth 1 https://github.com/bokeh/bokeh.git
+cd bokeh/bokehjs
+node make build
+npm pack
+```
+
+This will produce the file `bokeh-bokehjs-3.8.0-dev.1.tgz` which should be copied to the root
+directory of your `bokehjs-examples` repository.
+
+When Bokeh and BokehJS 4.0 are released, these instructions and the code within this repository
+will be updated to reflect the simpler installation process.
