+Environment Variables
+=====================
+
+CircuitPython 8.0.0 introduces support for environment variables. Environment
+variables are commonly used to store "secrets" such as Wi-Fi passwords and API
+keys. This method *does not* make them secure. It only separates them from the
+code.
+
+CircuitPython supports these by mimicking the `dotenv <https://github.com/theskumar/python-dotenv>`_
+CPython library. Other languages such as Javascript, PHP and Ruby also have
+dotenv libraries.
+
+These libraries store environment variables in a ``.env`` file. Here is a simple
+example:
+
+.. code-block:: bash
+
+  KEY1='value1'
+  # Comment
+  KEY2='value2
+  is multiple lines'
+
+CircuitPython uses the ``.env`` at the drive root (no folder) as the environment.
+User code can access the values from the file using `os.getenv()`. It is
+recommended to save any values used repeatedly in a variable because `os.getenv()`
+will parse the ``/.env`` on every access.
+
+CircuitPython behavior
+----------------------
+
+CircuitPython will also read the environment to configure its behavior. Other
+keys are ignored by CircuitPython. Here are the keys it uses:
+
+CIRCUITPY_BLE_NAME
+~~~~~~~~~~~~~~~~~~
+Default BLE name the board advertises as, including for the BLE workflow.
+
+CIRCUITPY_WEB_API_PASSWORD
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+Password required to make modifications to the board from the Web Workflow.
+
+CIRCUITPY_WIFI_PASSWORD
+~~~~~~~~~~~~~~~~~~~~~~~
+Wi-Fi password used to auto connect to CIRCUITPY_WIFI_SSID.
+
+CIRCUITPY_WIFI_SSID
+~~~~~~~~~~~~~~~~~~~
+Wi-Fi SSID to auto-connect to even if user code is not running.

+# Workflows
+
+Workflows are the process used to 1) manipulate files on the CircuitPython device and 2) interact
+with the serial connection to CircuitPython. The serial connection is usually used to access the
+REPL.
+
+Starting with CircuitPython 3.x we moved to a USB-only workflow. Prior to that, we used the serial
+connection alone to do the whole workflow. In CircuitPython 7.x, a BLE workflow was added with the
+advantage of working with mobile devices. CircuitPython 8.x added a web workflow that works over the
+local network (usually Wi-Fi) and a web browser. Other clients can also use the Web REST API. Boards
+should clearly document which workflows are supported.
+
+Code for workflows lives in `supervisor/shared`.
+
+The workflow APIs are documented here.
+
+## USB
+
+These USB interfaces are enabled by default on boards with USB support. They are usable once the
+device has been plugged into a host.
+
+### CIRCUITPY drive
+CircuitPython exposes a standard mass storage (MSC) interface to enable file manipulation over a
+standard interface. This interface works underneath the file system at the block level so using it
+excludes other types of workflows from manipulating the file system at the same time.
+
+### CDC serial
+CircuitPython exposes one CDC USB interface for CircuitPython serial. This is a standard serial
+USB interface.
+
+TODO: Document how it designates itself from the user CDC.
+
+Setting baudrate 1200 and disconnecting will reboot into a bootloader. (Used by Arduino to trigger
+a reset into bootloader.)
+
+## BLE
+
+The BLE workflow is enabled for nRF boards. By default, to prevent malicious access, it is disabled.
+To connect to the BLE workflow, press the reset button while the status led blinks blue quickly
+after the safe mode blinks. The board will restart and broadcast the file transfer service UUID
+(`0xfebb`) along with the board's [Creation IDs](https://github.com/creationid/creators). This
+public broadcast is done at a lower transmit level so the devices must be closer. On connection, the
+device will need to pair and bond. Once bonded, the device will broadcast whenever disconnected
+using a rotating key rather than a static one. Non-bonded devices won't be able to resolve it. After
+connection, the central device can discover two default services. One for file transfer and one for
+CircuitPython specifically that includes serial characteristics.
+
+To change the default BLE advertising name without (or before) running user code, the desired name
+can be put in the `/.env` file. The key is `CIRCUITPY_BLE_NAME`. It's limited to approximately
+30 characters depending on the port's settings and will be truncated if longer.
+
+### File Transfer API
+
+CircuitPython uses [an open File Transfer API](https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer)
+to enable file system access.
+
+### CircuitPython Service
+
+The base UUID for the CircuitPython service is `ADAFXXXX-4369-7263-7569-7450794686e`. The `XXXX` is
+replaced by the four specific digits below. The service itself is `0001`.
+
+#### TX - `0002` / RX - `0003`
+
+These characteristic work just like the Nordic Uart Service (NUS) but have different UUIDs to prevent
+conflicts with user created NUS services.
+
+#### Version - `0100`
+Read-only characteristic that returns the UTF-8 encoded version string.
+
+## Web
+
+The web workflow is depends on adding Wi-Fi credentials into the `/.env` file. The keys are
+`CIRCUITPY_WIFI_SSID` and `CIRCUITPY_WIFI_PASSWORD`. Once these are defined, CircuitPython will
+automatically connect to the network and start the webserver used for the workflow. The webserver
+is on port 80. It also enables MDNS.
+
+Here is an example `/.env`:
+
+```bash
+# To auto-connect to Wi-Fi
+CIRCUITPY_WIFI_SSID='scottswifi'
+CIRCUITPY_WIFI_PASSWORD='secretpassword'
+
+# To enable modifying files from the web. Change this too!
+CIRCUITPY_WEB_API_PASSWORD='passw0rd'
+```
+
+MDNS is used to resolve [`circuitpython.local`](http://circuitpython.local) to a device specific
+hostname of the form `cpy-XXXXXX.local`. The `XXXXXX` is based on network MAC address. The device
+also provides the MDNS service with service type `_circuitpython` and protocol `_tcp`.
+
+### HTTP
+The web server is HTTP 1.1 and may use chunked responses so that it doesn't need to precompute
+content length.
+
+The API generally consists of an HTTP method such as GET or PUT and a path. Requests and responses
+also have headers. Responses will contain a status code and status text such as `404 Not Found`.
+This API tries to use standard status codes to encode the status of the various operations. The
+[Mozilla Developer Network HTTP docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP)
+are a great reference.
+
+#### Examples
+The examples use `curl`, a common command line program for issuing HTTP requests. The examples below
+use `circuitpython.local` as the easiest way to work. If you have multiple active devices, you'll
+want to use the specific `cpy-XXXXXX.local` version.
+
+The examples also use `passw0rd` as the password placeholder. Replace it with your password before
+running the example.
+
+### `/`
+The root welcome page links to the file system page and also displays other CircuitPython devices
+found using MDNS service discovery. This allows web browsers to find other devices from one. (All
+devices will respond to `circuitpython.local` so the device redirected to may vary.)
+
+### CORS
+The web server will allow requests from `cpy-XXXXXX.local`, `127.0.0.1`, the device's IP and
+`code.circuitpython.org`. (`circuitpython.local` requests will be redirected to `cpy-XXXXXX.local`.)
+
+### File REST API
+All file system related APIs are protected by HTTP basic authentication. It is *NOT* secure but will
+hopefully prevent some griefing in shared settings. The password is sent unencrypted so do not reuse
+a password with something important.
+
+The password is taken from `/.env` with the key `CIRCUITPY_WEB_API_PASSWORD`. If this is unset, the
+server will respond with `403 Forbidden`. When a password is set, but not provided in a request, it
+will respond `401 Unauthorized`.
+
+#### `/fs/`
+
+The `/fs/` page will respond with a directory browsing HTML once authenticated. This page is always
+gzipped. If the `Accept: application/json` header is provided, then the JSON representation of the
+root will be returned.
+
+##### OPTIONS
+When requested with the `OPTIONS` method, the server will respond with CORS related headers. Most
+aren't needed for API use. They are there for the web browser.
+
+* `Access-Control-Allow-Methods` - Varies with USB state. `GET, OPTIONS` when USB is active. `GET, OPTIONS, PUT, DELETE` otherwise.
+
+Example:
+
+```sh
+curl -v -u :passw0rd -X OPTIONS -L --location-trusted http://circuitpython.local/fs/
+```
+
+#### `/fs/<directory path>/`
+Directory paths must end with a /. Otherwise, the path is assumed to be a file.
+
+##### GET
+Returns a JSON representation of the directory.
+
+* `200 OK` - Directory exists and JSON returned
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `404 Not Found` - Missing directory
+
+Returns information about each file in the directory:
+
+* `name` - File name. No trailing `/` on directory names
+* `directory` - `true` when a directory. `false` otherwise
+* `modified_ns` - File modification time in nanoseconds since January 1st, 1970. May not use full resolution
+* `file_size` - File size in bytes. `0` for directories
+
+Example:
+
+```sh
+curl -v -u :passw0rd -H "Accept: application/json" -L --location-trusted http://circuitpython.local/fs/lib/hello/
+```
+
+```json
+[
+	{
+		"name": "world.txt",
+		"directory": false,
+		"modified_ns": 946934328000000000,
+		"file_size": 12
+	}
+]
+```
+
+##### PUT
+Tries to make a directory at the given path. Request body is ignored. The custom `X-Timestamp`
+header can provide a timestamp in milliseconds since January 1st, 1970 (to match JavaScript's file
+time resolution) used for the directories modification time. The RTC time will used otherwise.
+
+Returns:
+
+* `204 No Content` - Directory exists
+* `201 Created` - Directory created
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `409 Conflict` - USB is active and preventing file system modification
+* `404 Not Found` - Missing parent directory
+* `500 Server Error` - Other, unhandled error
+
+Example:
+
+```sh
+curl -v -u :passw0rd -X PUT -L --location-trusted http://circuitpython.local/fs/lib/hello/world/
+```
+
+##### DELETE
+Deletes the directory and all of its contents.
+
+* `204 No Content` - Directory and its contents deleted
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `404 Not Found` - No directory
+* `409 Conflict` - USB is active and preventing file system modification
+
+Example:
+
+```sh
+curl -v -u :passw0rd -X DELETE -L --location-trusted http://circuitpython.local/fs/lib/hello/world/
+```
+
+
+#### `/fs/<file path>`
+
+##### PUT
+Stores the provided content to the file path.
+
+The custom `X-Timestamp` header can provide a timestamp in milliseconds since January 1st, 1970
+(to match JavaScript's file time resolution) used for the directories modification time. The RTC
+time will used otherwise.
+
+Returns:
+
+* `201 Created` - File created and saved
+* `204 No Content` - File existed and overwritten
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `404 Not Found` - Missing parent directory
+* `409 Conflict` - USB is active and preventing file system modification
+* `413 Payload Too Large` - `Expect` header not sent and file is too large
+* `417 Expectation Failed` - `Expect` header sent and file is too large
+* `500 Server Error` - Other, unhandled error
+
+If the client sends the `Expect` header, the server will reply with `100 Continue` when ok.
+
+Example:
+
+```sh
+echo "Hello world" >> test.txt
+curl -v -u :passw0rd -T test.txt -L --location-trusted http://circuitpython.local/fs/lib/hello/world.txt
+```
+
+##### GET
+Returns the raw file contents. `Content-Type` will be set based on extension:
+
+* `text/plain` - `.py`, `.txt`
+* `text/javascript` - `.js`
+* `text/html` - `.html`
+* `application/json` - `.json`
+* `application/octet-stream` - Everything else
+
+Will return:
+* `200 OK` - File exists and file returned
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `404 Not Found` - Missing file
+
+Example:
+
+```sh
+curl -v -u :passw0rd -L --location-trusted http://circuitpython.local/fs/lib/hello/world.txt
+```
+
+
+##### DELETE
+Deletes the file.
+
+
+* `204 No Content` - File existed and deleted
+* `401 Unauthorized` - Incorrect password
+* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set
+* `404 Not Found` - File not found
+* `409 Conflict` - USB is active and preventing file system modification
+
+Example:
+
+```sh
+curl -v -u :passw0rd -X DELETE -L --location-trusted http://circuitpython.local/fs/lib/hello/world.txt
+```
+
+### `/cp/`
+
+`/cp/` serves basic info about the CircuitPython device and others discovered through MDNS. It is
+not protected by basic auth in case the device is someone elses.
+
+Only `GET` requests are supported and will return `405 Method Not Allowed` otherwise.
+
+#### `/cp/devices.json`
+
+Returns information about other devices found on the network using MDNS.
+
+* `total`: Total MDNS response count. May be more than in `devices` if internal limits were hit.
+* `devices`: List of discovered devices.
+	* `hostname`: MDNS hostname
+	* `instance_name`: MDNS instance name. Defaults to human readable board name.
+	* `port`: Port of CircuitPython Web API
+	* `ip`: IP address
+
+Example:
+```sh
+curl -v -L http://circuitpython.local/cp/devices.json
+```
+
+```json
+{
+	"total": 1,
+	"devices": [
+		{
+			"hostname": "cpy-951032",
+			"instance_name": "Adafruit Feather ESP32-S2 TFT",
+			"port": 80,
+			"ip": "192.168.1.235"
+		}
+	]
+}
+```
+
+#### `/cp/serial/`
+
+
+Serves a basic serial terminal program when a `GET` request is received without the
+`Upgrade: websocket` header. Otherwise the socket is upgraded to a WebSocket. See WebSockets below for more detail.
+
+This is an authenticated endpoint in both modes.
+
+#### `/cp/version.json`
+
+Returns information about the device.
+
+* `web_api_version`: Always `1`. This versions the rest of the API and new versions may not be backwards compatible.
+* `version`: CircuitPython build version.
+* `build_date`: CircuitPython build date.
+* `board_name`: Human readable name of the board.
+* `mcu_name`: Human readable name of the microcontroller.
+* `board_id`: Board id used in code and on circuitpython.org.
+* `creator_id`: Creator ID for the board.
+* `creation_id`: Creation ID for the board, set by the creator.
+* `hostname`: MDNS hostname.
+* `port`: Port of CircuitPython Web Service.
+* `ip`: IP address of the device.
+
+Example:
+```sh
+curl -v -L http://circuitpython.local/cp/version.json
+```
+
+```json
+{
+	"web_api_version": 1,
+	"version": "8.0.0-alpha.1-20-ge1d4518a9-dirty",
+	"build_date": "2022-06-24",
+	"board_name": "ESP32-S3-USB-OTG-N8",
+	"mcu_name": "ESP32S3",
+	"board_id": "espressif_esp32s3_usb_otg_n8",
+	"creator_id": 12346,
+	"creation_id": 28683,
+	"hostname": "cpy-f57ce8",
+	"port": 80,
+	"ip": "192.168.1.94"
+}
+```
+
+### Static files
+
+* `/favicon.ico` - Blinka
+* `/directory.js` - JavaScript for `/fs/`
+* `/welcome.js` - JavaScript for `/`
+
+### WebSocket
+
+The CircuitPython serial interactions are available over a WebSocket. A WebSocket begins as a
+special HTTP request that gets upgraded to a WebSocket. Authentication happens before upgrading.
+
+WebSockets are *not* bare sockets once upgraded. Instead they have their own framing format for data.
+CircuitPython can handle PING and CLOSE opcodes. All others are treated as TEXT. Data to
+CircuitPython is expected to be masked UTF-8, as the spec requires. Data from CircuitPython to the
+client is unmasked. It is also unbuffered so the client will get a variety of frame sizes.
+
+Only one WebSocket at a time is supported.
