 :::warning
 GPIO access is fundamentally dangerous because invalid options can physically damage or destroy your hardware. Ensure that you fully understand the schematic for your particular device before trying this as we do not offer a warranty. Use at your own risk.
 :::
 
-The device firmware runs on the nodes to build the mesh for communication. Each different make and model of device requires a different build of the Meshtastic firmware in order to run properly. Thankfully, due to the design of Meshtastic, it is possible to port the firmware to new devices as they become available. The firmware currently runs on a range of ESP32 based devices, but there is also increasing support for the nRF52 microprocessor with some more recent devices coming to market.
-
-The current firmware has support for a screen to display received messages, along with information about nodes on the mesh, and more detailed information about the device on which it is running.
-
-The latest firmware can be downloaded from the [Downloads](/downloads) page. If you wish to view the code or contribute to development of the firmware, please visit the device code [GitHub page](https://github.com/meshtastic/firmware).
-
-:::info
-Please be aware that there are significant changes between version branches 1.2.x and 1.3.x which mean that devices need to be running the same branch of firmware to be able to talk to each other. Python, Android, and other software applications will also need to be running the same branch to be able to talk to the device.
-
-This feature uses a preinstalled module in the device code and associated command line flags/classes in the python code. You'll need to be running at least version 1.2.23 (or later) of the python and device code to use this feature.

-## Considerations
+## Overview
 
-We have a total of 458,752 bytes (448KB) available on the SPIFFS (Serial Peripheral Interface Flash File System) -- the on-board storage of the ESP32. Of that space, let's not use more than half of that (224KB) in order to leave space for other uses.
+The Meshtastic web interface can be hosted or served from a node.
 
-Right now, the Meshtastic Device Preferences as well as SSL keys use that space. We can imagine other future uses as well, such as logging chat messages and possibly saving received signal strength with GPS coordinates to create coverage heat maps.
+The official hosted version can be found at [https://client.meshtastic.org](https://client.meshtastic.org).
 
-## Static Files
+The version served from a node can be accessed by first [connecting your node to your network](/docs/settings/config/network) and then navigating to http://meshtastic.local (or your_node_ip.local).
 
-Static files can be placed in the /data folder. All files should be compressed in the .gz format with a .gz extension regardless of the file type.
 
-As an example, this would mean we will have files such as:
+## Development & Building
 
-- style.css.gz
-- meshtastic.js.gz
-- meshtasticlogo.png.gz
+### Development
 
-Unless otherwise stated, files in the `/data` folder of the source code will be stored in `/static` on the device.
+Clone the [Meshtastic Web Repo](https://github.com/meshtastic/web) repository
+   ```shell
+   git clone https://github.com/meshtastic/web.git
+   cd web
+   ```
 
-## Application Interface
+Install the dependencies.
 
-We make extensive use of [Meshtastic.js](https://github.com/meshtastic/meshtastic.js).
+```bash
+pnpm i
+```
+### Building
 
-## Embedded Server
+Build the project:
 
-### Root
+```bash
+pnpm build
+```
 
-When requesting to the root of the web server, the either /static/index.html or /static/index.html.gz will be fetched from the file system and served to the client. We require that the file is in the gzip format. Serving an uncompressed file is not supported. If both index.html and index.html.gz are on the filesystem, index.html will be served and index.html.gz will be ignored.
+Start the development server:
 
-### /static
+```bash
+pnpm dev
+```
 
-All files stored in /data/static in the Meshtastic source code will be available in /static on the Meshtastic device.
+### Packaging
 
-If a file is uploaded in a .gz format, the .gz extension will be stripped prior to being served to the client. Keep your filenames as short as possible. Short filenames work better than long file names.
+Build the project:
 
-An experimental file system browser with upload and delete capability is available by going to either:
+```bash
+pnpm build
+```
 
-- http://meshtastic.local/static
-- https://meshtastic.local/static
+GZip the output:
 
-There are known issues with uploading files with large file sizes.
+```bash
+pnpm package
+```
 
-The current preferred method to upload data is through PlatformIO and the file system browser is provided without guarantees.
 
-### /restart
+## Releases
 
-A post to this location will cause the device to restart.
+Releases are automatically generated for every commit as per out [CI](https://github.com/meshtastic/web/blob/master/.github/workflows/main.yml). This performs two actions:
 
-### /favicon.ico
-
-The Meshtastic logo in .ico format.
-
-### /hotspot-detect.html
-
-Used by the Apple Captive Portal Assistant.
-
-### /upload
-
-Endpoint to upload files. Used by the file manager.
-
-### /json/report
-
-Return a report of airtime statistics and current status.
-
-Formula to calculate when the current time period will roll over:
-
-`data.airtime.seconds_per_period - (data.airtime.seconds_since_boot % data.airtime.seconds_per_period)`
-
-### /json/scanNetworks
-
-Returns a json data structure of WiFi networks in the area. It's recommended to call this at least 2 or 3 times and combine the results.
-
-We purposely exclude open (insecure) networks from the list.
-
-### /json/spiffs/browse/static
-
-Returns a json data structure with the contents of /static.
-
-If a filename includes a '.gz' extension, will also return a modified version of the filename with the extension stripped. This is to support the functionality in /static (see above).
-
-### /json/spiffs/delete/static
-
-Delete file specified by the parameter "delete". Use the method "DELETE".
-
-eg: /json/spiffs/delete/static?delete=static/something.txt
-
-### Performance
-
-As a general guide, the ESP32 will return HTTP requests significantly faster than HTTPS requests. For responses of 1kb or less, expect the following for real world performance:
-
-HTTP - 3.0 requests / sec
-HTTPS - 0.4 requests / sec
-
-The bottleneck of HTTPS is with the SSL handshake. We will get better performance serving one large file rather than multiple small files.

-FIXME - Investigate and rewrite document to reflect the current ESP32 Partition mitigation.
-:::
-
-## Insufficient space to upload web interface files
-
-This problem seems to occur when your board has the partitioning structure set incorrectly. This typically occurs when the board has had a firmware other than Meshtastic on it previously. In this situation, the file upload page on the device typically shows a free space of around 48,000 bytes, rather than the ~300,000 bytes that it should have free.
-
-![Meshtastic.local's upload page showing insufficient storage space](/img/insufficient-space.png)
-
-There are a number of methods that essentially involve erasing the flash and then re-uploading the Meshtastic firmware.
-
-## Install Script
-
-The most reliable way to fix this problem is to use the install script that is included in the meshtastic firmware zip. If that doesn’t work, these other methods may work:
-
-## Alternative methods
-
-### Using the Arduino IDE:
-
-https://meshtastic.discourse.group/t/solved-help-installing-with-other-than-esphome-flasher/2214/9
-
-### Using Pio in Windows
-
-```powershell
-pio run --target erase --environment tbeam
-```
-
-Then re-install the firmware ie using ESPHome Flasher.
-
-Requires: [Python](https://www.python.org), [Pio](https://pypi.org/project/pio), command to be run in the root directory of the firmware project once you’ve cloned it (this last requirement is an assumption based on pio not knowing what a tbeam is, may also require Visual Studio Code and PlatformIO as these were installed during use).
-
-### Esptool.py
-
-@1984 posted another method using the python based esptool.py to erase and re-flash the firmware:
-
-```shell
-esptool.py --baud 921600 erase_flash
-esptool.py --baud 921600 write_flash 0x1000 system-info.bin
-esptool.py --baud 921600 write_flash 0x00390000 spiffs-*.bin
-esptool.py --baud 921600 write_flash 0x10000 firmware-tbeam-EU865-1.1.42.bin
-```
-
-Requires: [Python](https://www.python.org) and [esptool.py](https://github.com/espressif/esptool)
-
-### Visual Studio & PlatformIO
-
-There is also the method of using the Visual Studio IDE. This requires having Visual Studio and PlatformIO installed, along with having cloned the firmware code as per the [build instructions](/docs/development/firmware/build). After loading the project in Visual Studio, select the PlatformIO alien icon, then find the appropriate device, and then click the Erase Flash command.
-
-![Erasing the flash using PlatformIO in Visual Studio Code](/img/platformio-erase.png)
-
-https://meshtastic.discourse.group/t/configuring-channel-via-python-api/1948/17
-
-Requires: [Visual Studio Code](https://code.visualstudio.com), [PlatformIO](https://platformio.org), cloned copy of the Meshtastic Firmware project
-
-## How do I know it's worked?
-
-Once it has been successfully erased and re-flashed, visiting https://192.168.42.1/static should leave you with free space on the order of 300,000 bytes, rather than the ~48,000 bytes you currently have. You can then upload the files from the meshtastic web release.
-
-Occasionally, this may glitch may appear when uploading the larger app.js.gz file, but a further erase and flash typically solves this.

+When MQTT is enabled, the Meshtastic device simply uplinks and/or downlinks every raw protobuf MeshPacket that it sees to the MQTT broker, encapsulated in a [ServiceEnvelope protobuf](https://buf.build/meshtastic/protobufs/docs/main:meshtastic#meshtastic.ServiceEnvelope).

All packets are sent to the broker, whether they originate from another device on the mesh, or the gateway node itself.
 
 Packets may be encrypted. If you use the default meshtastic MQTT server, packets are always encrypted. If you use a custom MQTT broker (ie set `mqtt.address`), the `mqtt.encryption_enabled` setting applies, which by default is false.
 
 IMPORTANT: When MQTT is turned on, you are potentially broadcasting your entire mesh traffic onto the public internet. This includes messages and position information.

+The meaning of these fields is as follows:
+
+- "`id`" is the unique ID for this message. 
+- "`channel`" is the channel index this message was received on.
+- "`from`" is the unique node number of the node on the mesh that sent this message, represented as a signed decimal number.
+- "`id`" inside the payload of a `NODEINFO_APP` message is the user ID of the node that sent it, which is currently just the hexadecimal representation of the node number. 
+- "`hardware`" is the [hardware model](https://github.com/meshtastic/protobufs/blob/master/meshtastic/mesh.proto#L215) of the node sending the `NODEINFO_APP` message.
+- "`longname`" is the long name of the device that sent the `NODEINFO_APP` message.
+- "`shortname`" is the short name of the device that sent the `NODEINFO_APP` message.
+- "`sender`" is the user ID of the gateway device, which is in this case the same node that sent the `NODEINFO_APP` message (the hexadecimal value `7efeee00` represented by an integer in decimal is `2130636288`). 
+- "`timestamp`" is the Unix Epoch when the message was received, represented as an integer in decimal.
+- "`to`" is the node number of the destination of the message. In this case, "-1" means it was a broadcast message (this is the decimal integer representation of `0xFFFFFFFF`). 
+- "`type`" is the type of the message, in this case it was a `NODEINFO_APP` message.
+
+The "from" field can thus be used as a stable identifier for a specific node. Note that (like the "`id`" and "`to`" fields) in JSON this is a signed value, whereas in protobufs it is unsigned.

 If the message received contains valid JSON in the payload, the JSON is deserialized and added as a JSON object rather than a string containing the serialized JSON.

-### Topics
-
-The "mesh/crypt/CHANNELID/NODEID/PORTID" [topic](https://www.hivemq.com/blog/mqtt-essentials-part-5-mqtt-topics-best-practices) will be used for messages sent from/to a mesh.
-
-Gateway nodes will forward any MeshPacket from a local mesh channel with uplink_enabled. The packet (encapsulated in a ServiceEnvelope) will remain encrypted with the key for the specified channel.
-
-For any channels in the local node with downlink_enabled, the gateway node will forward packets from MQTT to the local mesh. It will do this by subscribing to mesh/crypt/CHANNELID/# and forwarding relevant packets.
-
-If the channelid 'well known'/public it could be decrypted by a web service (if the web service was provided with the associated channel key), in which case it will be decrypted by a web service and appear at "mesh/clear/CHANNELID/NODEID/PORTID". Note: This is not in the initial deliverable.
-
-#### Service Envelope
-
-The payload published on mesh/... will always be wrapped in a [ServiceEnvelope protobuf](https://buf.build/meshtastic/protobufs/docs/main:meshtastic#meshtastic.ServiceEnvelope).
-
-ServiceEnvelope will include the message, and full information about arrival time, who forwarded it, source channel, source mesh id, etc...
-
-#### NODEID
-
-The unique ID for a node. A hex string that starts with an ! symbol.
-
-#### USERID
-
-A user ID string. This string is either a user ID if known or a nodeid to simply deliver the message to whoever the local user is of a particular device (i.e. person who might see the screen). FIXME, see what riot.im uses and perhaps use that convention? Or use the signal +phone number convention? Or the email address?
-
-#### CHANNELID
-
-FIXME, figure out how channelids work

 ### Gateway nodes
 
 Any meshtastic node that has a direct connection to the internet (either via a helper app or installed WiFi/4G/satellite hardware) can function as a "Gateway node".
