+# Code of Conduct
+
+The [PyScript Code of Conduct](https://github.com/pyscript/governance/blob/main/CODE-OF-CONDUCT.md) governs the project and everyone participating in it. By participating, you are expected to uphold this code. Please report unacceptable behavior to the maintainers or administrators as described in that document.
+
+# Contributing
+
+## Reporting bugs
+
+Bugs are tracked on the [project issues page](https://github.com/pyscript/pyscript/issues). Please check if your issue has already been filed by someone else by searching the existing issues before filing a new one. Once your issue is filed, it will be triaged by another contributor or maintainer. If there are questions raised about your issue, please respond promptly.
+
+## Creating useful issues
+
+-   Use a clear and descriptive title.
+-   Describe the specific steps that reproduce the problem with as many details as possible so that someone can verify the issue.
+-   Describe the behavior you observed, and the behavior you had expected.
+-   Include screenshots if they help make the issue clear.
+
+## Reporting security issues
+
+If you aren't confident that it is appropriate to submit a security issue using the above process, you can e-mail it to security@pyscript.net
+
+## Asking questions
+
+If you have questions about the project, using PyScript, or anything else, please ask in the [PyScript forum](https://community.anaconda.cloud/c/tech-topics/pyscript).
+
+## Places to start
+
+If you would like to contribute to PyScript, but you aren't sure where to begin, here are some suggestions:
+
+-   **Read over the existing documentation.** Are there things missing, or could they be clearer? Make some changes/additions to those documents.
+-   **Review the open issues.** Are they clear? Can you reproduce them? You can add comments, clarifications, or additions to those issues. If you think you have an idea of how to address the issue, submit a fix!
+-   **Look over the open pull requests.** Do you have comments or suggestions for the proposed changes? Add them.
+-   **Check out the examples.** Is there a use case that would be good to have sample code for? Create an example for it.
+
+## Setting up your local environment and developing
+
+If you would like to contribute to PyScript, you will need to set up a local development environment. The [following instructions](https://docs.pyscript.net/latest/development/setting-up-environment.html) will help you get started.
+
+You can also read about PyScript's [development process](https://docs.pyscript.net/latest/development/developing.html) to learn how to contribute code to PyScript, how to run tests and what's the PR etiquette of the community!

 # PyScript
 
-## PyScript is an open source platform for Python in the browser.
+## What is PyScript
 
-Using PyScript is as simple as:
+### Summary
+
+PyScript is a framework that allows users to create rich Python applications in the browser using HTML's interface and the power of [Pyodide](https://pyodide.org/en/stable/), [WASM](https://webassembly.org/), and modern web technologies.
+
+To get started see the [getting started tutorial](docs/tutorials/getting-started.md).
+
+For examples see [here](examples).
+
+### Longer Version
+
+PyScript is a meta project that aims to combine multiple open technologies into a framework that allows users to create sophisticated browser applications with Python. It integrates seamlessly with the way the DOM works in the browser and allows users to add Python logic in a way that feels natural both to web and Python developers.
+
+## Try PyScript
+
+To try PyScript, import the appropriate pyscript files into the `<head>` tag of your html page with:
 
 ```html
-<!doctype html>
-<html lang="en">
-    <head>
-        <meta charset="utf-8" />
-        <meta name="viewport" content="width=device-width,initial-scale=1" />
-        <title>PyScript!</title>
-        <link
-            rel="stylesheet"
-            href="https://pyscript.net/releases/2025.11.2/core.css"
-        />
-        <script
-            type="module"
-            src="https://pyscript.net/releases/2025.11.2/core.js"
-        ></script>
-    </head>
-    <body>
-        <!-- type mpy (MicroPython) or py (Pyodide) to run some Python -->
-        <script type="mpy" terminal>
-            print("Hello, world!")
-        </script>
-    </body>
-</html>
+<head>
+    <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
+    <script defer src="https://pyscript.net/latest/pyscript.js"></script>
+</head>
 ```
 
-PyScript enables the creation of rich Python applications in the browser using
-[Pyodide](https://pyodide.org/en/stable/) (a version of
-[CPython](https://python.org/)), [MicroPython](https://micropython.org/),
-[WASM](https://webassembly.org/), and modern web technologies. It means Python
-now runs anywhere a browser runs: desktop, laptop, mobile, tablet, or any other
-browser enabled device.
+You can then use PyScript components in your html page. PyScript currently implements the following elements:
 
-To start building, read the
-[Beginning PyScript tutorial](https://docs.pyscript.net/latest/beginning-pyscript/).
+-   `<py-script>`: can be used to define python code that is executable within the web page. The element itself is not rendered to the page and is only used to add logic
+-   `<py-repl>`: creates a REPL component that is rendered to the page as a code editor and allows users to write executable code
 
-For example applications, see [here](https://pyscript.com/@examples).
+Check out the [the examples directory](examples) folder for more examples on how to use it, all you need to do is open them in Chrome.

+
+## Make setup
+
+A lot of problems related to `make setup` are related to node and npm being outdated. Once npm and node are updated, `make setup` should work. You can follow the steps on the [npm documentation](https://docs.npmjs.com/try-the-latest-stable-version-of-npm) to update npm (the update command for Linux should work for Mac as well). Once npm has been updated you can continue to the instructions to update node below.
+
+To update Node run the following commands in order (Most likely you'll be prompted for your user password, this is normal):
+
+```
+sudo npm cache clean -f
+sudo npm install -g n
+sudo n stable
+```

-# @pyscript/bridge
-
-Import Python utilities directly in JS
-
-```js
-// main thread
-const { ffi: { func_a, func_b } } = await import('./test.js');
-
-// test.js
-import bridge from 'https://esm.run/@pyscript/bridge';
-export const ffi = bridge(import.meta.url, { type: 'mpy', worker: false });
-
-// test.py
-def func_a(value):
-    print(f"hello {value}")
-
-def func_b():
-    import sys
-    return sys.version
-```
-
-### Options
-
-  * **pyscript**: the release version to automatically import if not already available on the page. If no version is provided the *developers' channel* version will be used instead (for developers' purposes only).
-  * **type**: `py` by default to bootstrap *Pyodide*.
-  * **worker**: `true` by default to bootstrap in a *Web Worker*.
-  * **config**: either a *string* or a PyScript compatible config *JS literal* to make it possible to bootstrap files and whatnot. If specified, the `worker` becomes implicitly `true` to avoid multiple configs conflicting on the main thread.
-  * **env**: to share the same environment across multiple modules loaded at different times.
-
-
-## Tests
-
-Run `npx mini-coi .` within this folder to then reach out `http://localhost:8080/test/` that will show:
-
-```
-PyScript Bridge
-------------------
-no config
-```
-
-The [test.js](./test/test.js) files uses the following defaults:
-
-  * `pyscript` as `"2025.8.1"`
-  * `type` as `"mpy"`
-  * `worker` as `false`
-  * `config` as `undefined`
-  * `env` as `undefined`
-
-To test any variant use query string parameters so that `?type=py` will use `py` instead, `worker` will use a worker and `config` will use a basic *config* that brings in another file from the same folder which exposes the version.
-
-To recap: `http://localhost:8080/test/?type=py&worker&config` will show this instead:
-
-```
-PyScript Bridge
-------------------
-3.12.7 (main, May 15 2025, 18:47:24) ...
-```
-
-Please note when a *config* is used, the `worker` attribute is always `true`.

-# @pyscript/core
-
-PyScript brings two Python interpreters to the browser:
-
--   [MicroPython](https://micropython.org/) - a lean and efficient implementation
-    of the Python 3 programming language that includes a small subset of the
-    Python standard library and is optimised to run on microcontrollers and in
-    constrained environments (like the browser).
--   [Pyodide](https://pyodide.org)) - a port of all CPython to WebAssembly.
-
-These interpreters are compiled to [WebAssembly](https://webassembly.org/)
-(shortened to WASM). The browser provides a secure WASM computing sandbox. Both
-interpreters are compiled to web assembly with
-[Emscripten](https://emscripten.org/). PyScript core maintainers work closely
-with the core maintainers of both MicroPython and Pyodide (and CPython). We
-work hard to ensure PyScript works efficiently in browsers on all platforms:
-desktop, mobile, or elsewhere.
-
-Our technical documentation for using this project can be
-[found here](https://docs.pyscript.net/).
-
-PyScript sits on two further projects (both written in JavaScript):
-
-1. [polyscript](https://github.com/pyscript/polyscript/#readme) - used to
-   bootstrap WASM compiled interpreters in a browser.
-2. [coincident](https://github.com/WebReflection/coincident) - used to simplify
-   worker based tasks.
-
-PyScript itself is mostly written in JavaScript. The test suite for JavaScript
-is in two parts: automated tests run in [playwright](https://playwright.dev/),
-and manual tests you have to run in a browser and check yourself. PyScript also
-has a plugin system so third parties can extend its capabilities with
-JavaScript. Our built-in core plugins can be found in the `src/plugins`
-directory. We describe how to write third party plugins in our
-[developer documentation](https://docs.pyscript.net/latest/user-guide/plugins/).
-
-We provide a `pyscript` namespace containing Python modules for common browser
-based APIs and features (i.e. you can `import pyscript` in Python code running
-inside PyScript, to access these features). The Python code for the `pyscript`
-namespace is in `src/stdlib/pyscript` with the associated test suite in
-`tests/python`. The tests use the browser friendly
-[uPyTest](https://github.com/ntoll/upytest) test framework for checking Python
-code running _within_ PyScript. All the Python tests are run in each each
-available interpreter in both the main thread and a web worker (i.e. the
-test suite is run four times, accounting for each combination of interpreter
-and main/worker context).
-
-When you create a local build all the automated tests (JavaScript and Python)
-are run.
-
-## Developer Guide
-
-Full instructions for setting up a working development environment, how to
-build PyScript and how to test it can be
-[found in our official docs](https://docs.pyscript.net/latest/developers/).
-
-The short version is:
-
--   Ensure you have Python, node and npm installed.
--   Create a Python virtual environment.
--   In the root of this repository `make setup`.
--   `make build` to build PyScript.
--   As dependencies change over time, `make update` to keep in sync.
-
-To start using the locally built version of PyScript, you'll need an HTML
-page something like this (note the relative paths to assets in the `dist`
-directory, in the `<head>` of the document):
-
-```html
-<!doctype html>
-<html lang="en">
-    <head>
-        <meta charset="UTF-8" />
-        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
-        <title>Pure Python PyScript tests</title>
-        <link rel="stylesheet" href="../../dist/core.css" />
-        <script type="module" src="../../dist/core.js"></script>
-    </head>
-    <body>
-        <script type="mpy" src="./main.py" config="./conf.toml"></script>
-    </body>
-</html>
-```
-
-Once set up, you should be able to run the most common activities via the
-`make` command:
-
-```
-$ make
-
-There is no default Makefile target right now. Try:
-
-make setup - check your environment and install the dependencies.
-make update - update dependencies.
-make clean - clean up auto-generated assets.
-make build - build PyScript.
-make precommit-check - run the precommit checks (run eslint).
-make test - run all automated tests in playwright.
-make fmt - format the code.
-make fmt-check - check the code formatting.
-```
-
-## Artifacts
-
-There are two main artifacts in this project:
-
--   **stdlib** and its content: `src/stdlib/pyscript.js` exposes, as a
-    JavaScript object literal, all the _Python_ content within the folder
-    (recursively).
--   **plugins** and its content: `src/plugins.js` exposes all available
-    _dynamic imports_, and is able to instrument the bundler to create files
-    apart from the `_dist/_` folder, so that by default _core_ remains as small
-    as possible.
-
-Accordingly, whenever a file contains this warning at its first line, **please
-do not change such file directly before submitting a merge request**, as that
-file will be overwritten at the next `npm run build` command, either here or
-in _CI_:
-
-```js
-// ⚠️ This file is an artifact: DO NOT MODIFY
-```
-
-## Plugins
-
-While community or third party plugins don't need to be part of this repository
-and can be added just importing `@pyscript/core` as module, there are a few
-plugins that we would like to make available by default and these are
-considered _core plugins_.
-
-To add a _core plugin_ to this project define the plugin entry-point and name
-in the `src/plugins` folder (see the `error.js` example) and create, if
-necessary, a folder with the same name where extra files or dependencies can be
-added.
-
-The _build_ command will include plugins by name as artifacts so that the
-bundler can create ad-hoc files within the `dist/` folder.
-
-## Python
-
-The `pyscript` package available in _Python_ lives in the folder
-`src/stdlib/pyscript/`.
-
-All _Python_ files will be embedded automatically whenever `npm run build`
-happens and reflected into the `src/stdlib/pyscript.js` file.
-
-Its _core_ responsibility is to ensure those files will be available through
-the filesystem in either the _main_ thread, or any _worker_.
-
-## Release
-
-To cut a new release of PyScript simply
-[add a new release](https://github.com/pyscript/pyscript/releases) while
-remembering to write a comprehensive changelog. A
-[GitHub action](https://github.com/pyscript/pyscript/blob/main/.github/workflows/publish-release.yml)
-will kick in and ensure the release is described and deployed to a URL with the
-pattern: https://pyscript.net/releases/YYYY.M.v/ (year/month/version - as per
-our [CalVer](https://calver.org/) versioning scheme).
-
-Then, the following three separate repositories need updating:
-
--   [Documentation](https://github.com/pyscript/docs) - Change the `version.json`
-    file in the root of the directory and then `node version-update.js`.
--   [Homepage](https://github.com/pyscript/pyscript.net) - Ensure the version
-    referenced in `index.html` is the latest version.
--   [PSDC](https://pyscript.com) - Use discord or Anaconda Slack (if you work at
-    Anaconda) to let the PSDC team know there's a new version, so they can update
-    their project templates.

-# PyScript 3rd Party
-
-This folder contains artifacts created via [3rd-party.cjs](../../rollup/3rd-party.cjs).
-
-As we would like to offer a way to run PyScript offline, and we already offer a `dist` folder with all the necessary scripts, we have created a foreign dependencies resolver that allow to lazy-load CDN dependencies out of the box.
-
-Please **note** these dependencies are **not interpreters**, because interpreters have their own mechanism, folders structure, WASM files, and whatnot, to work locally, but at least XTerm or the TOML parser, among other lazy dependencies, should be available within the dist folder.

-"""
-This is the main `pyscript` namespace. It provides the primary Pythonic API
-for users to interact with the
-[browser's own API](https://developer.mozilla.org/en-US/docs/Web/API). It
-includes utilities for common activities such as displaying content, handling
-events, fetching resources, managing local storage, and coordinating with
-web workers.
-
-The most important names provided by this namespace can be directly imported
-from `pyscript`, for example:
-
-```python
-from pyscript import display, HTML, fetch, when, storage, WebSocket
-```
-
-The following names are available in the `pyscript` namespace:
-
-- `RUNNING_IN_WORKER`: Boolean indicating if the code is running in a Web
-  Worker.
-- `PyWorker`: Class for creating Web Workers running Python code.
-- `config`: Configuration object for pyscript settings.
-- `current_target`: The element in the DOM that is the current target for
-  output.
-- `document`: The standard `document` object, proxied in workers.
-- `window`: The standard `window` object, proxied in workers.
-- `js_import`: Function to dynamically import JS modules.
-- `js_modules`: Object containing JS modules available to Python.
-- `sync`: Utility for synchronizing between worker and main thread.
-- `display`: Function to render Python objects in the web page.
-- `HTML`: Helper class to create HTML content for display.
-- `fetch`: Function to perform HTTP requests.
-- `Storage`: Class representing browser storage (local/session).
-- `storage`: Object to interact with browser's local storage.
-- `WebSocket`: Class to create and manage WebSocket connections.
-- `when`: Function to register event handlers on DOM elements.
-- `Event`: Class representing user defined or DOM events.
-- `py_import`: Function to lazily import Pyodide related Python modules.
-
-If running in the main thread, the following additional names are available:
-
-- `create_named_worker`: Function to create a named Web Worker.
-- `workers`: Object to manage and interact with existing Web Workers.
-
-All of these names are defined in the various submodules of `pyscript` and
-are imported and re-exported here for convenience. Please refer to the
-respective submodule documentation for more details on each component.
-
-
-!!! Note
-    Some notes about the naming conventions and the relationship between
-    various similar-but-different names found within this code base.
-
-    ```python
-    import pyscript
-    ```
-
-    The `pyscript` package contains the main user-facing API offered by
-    PyScript. All the names which are supposed be used by end users should
-    be made available in `pyscript/__init__.py` (i.e., this source file).
-
-    ```python
-    import _pyscript
-    ```
-
-    The `_pyscript` module is an internal API implemented in JS. **End users
-    should not use it directly**. For its implementation, grep for
-    `interpreter.registerJsModule("_pyscript",...)` in `core.js`.
-
-    ```python
-    import js
-    ```
-
-    The `js` object is
-    [the JS `globalThis`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis),
-    as exported by Pyodide and/or Micropython's foreign function interface
-    (FFI). As such, it contains different things in the main thread or in a
-    worker, as defined by web standards.
-
-    ```python
-    import pyscript.context
-    ```
-
-    The `context` submodule abstracts away some of the differences between
-    the main thread and a worker. Its most important features are made
-    available in the root `pyscript` namespace. All other functionality is
-    mostly for internal PyScript use or advanced users. In particular, it
-    defines `window` and `document` in such a way that these names work in
-    both cases: in the main thread, they are the "real" objects, in a worker
-    they are proxies which work thanks to
-    [coincident](https://github.com/WebReflection/coincident).
-
-    ```python
-    from pyscript import window, document
-    ```
-
-    These are just the `window` and `document` objects as defined by
-    `pyscript.context`. This is the blessed way to access them from `pyscript`,
-    as it works transparently in both the main thread and worker cases.

-- Provides appropriate implementations of `window`, `document`, and `sync`.
-- Sets up JavaScript module import system, including a lazy `js_import`

-    [RequestInit dictionary](https://developer.mozilla.org/en-US/docs/Web/API/RequestInit),
-    and commonly include:
-
-    - `method`: HTTP method (e.g., `"GET"`, `"POST"`, `"PUT"` etc.)
-    - `headers`: Dict of request headers.
-    - `body`: Request body (string, dict for JSON, etc.)
-
-    The function returns a promise that resolves to a Response-like object
-    with Pythonic methods to extract data:
-
-    - `await response.json()` to get JSON as Python objects.
-    - `await response.text()` to get text data.
-    - `await response.bytearray()` to get raw data as a bytearray.
-    - `await response.arrayBuffer()` to get raw data as a memoryview or bytes.
-    - `await response.blob()` to get the raw JS Blob object.
-
-    It's also possible to chain these methods directly on the fetch promise:
-    `data = await fetch(url).json()`
-
-    The returned response object also exposes standard properties like
-    `ok`, `status`, and `statusText` for checking response status.
-
-    ```python
-    # Simple GET request.
-    response = await fetch("https://api.example.com/data")
-    data = await response.json()
-
-    # Method chaining.
-    data = await fetch("https://api.example.com/data").json()
-
-    # POST request with JSON.
-    response = await fetch(
-        "https://api.example.com/users",
-        method="POST",
-        headers={"Content-Type": "application/json"},
-        body=json.dumps({"name": "Alice"})
-    )
-    result = await response.json()
-
-    # Check response status codes.
-    response = await fetch("https://api.example.com/data")
-    if response.ok:
-        # Status in the range 200-299.
-        data = await response.json()
-    elif response.status == 404:
-        print("Resource not found")
-    else:
-        print(f"Error: {response.status} {response.statusText}")
-    ```
-    """
-    # Convert Python dict to JavaScript object.
-    js_options = js.JSON.parse(json.dumps(options))

-"""
-This module provides a unified
-[Foreign Function Interface (FFI)](https://en.wikipedia.org/wiki/Foreign_function_interface)
-layer for Python/JavaScript interactions, that works consistently across both
-Pyodide and MicroPython, and in a worker or main thread context, abstracting
-away the differences in their JavaScript interop APIs.
-
-The following utilities work on both the main thread and in worker contexts:
-
-- `create_proxy`: Create a persistent JavaScript proxy of a Python function.
-- `to_js`: Convert Python objects to JavaScript objects.
-- `is_none`: Check if a value is Python `None` or JavaScript `null`.
-- `assign`: Merge objects (like JavaScript's `Object.assign`).
-
-The following utilities are specific to worker contexts:
-
-- `direct`: Mark objects for direct JavaScript access.
-- `gather`: Collect multiple values from worker contexts.
-- `query`: Query objects in worker contexts.
-
-More details of the `direct`, `gather`, and `query` utilities
-[can be found here](https://github.com/WebReflection/reflected-ffi?tab=readme-ov-file#remote-extra-utilities).
