+# Information for Contributors
+
+Contributions in the form of pull requests, issue reports, and feature requests are welcome!
+
+## Common Terminology:
+* [Type]: Examples include feat (for new features), fix (for bug fixes), ci (for continuous integration), bump (for version updates), etc. You can find a comprehensive list of types in .pre-commit-config.yaml on line 65.
+* [Scope]: Refers to specific sections or areas within the project, such as mdns, modem, common, console, etc. You can discover additional scopes in .pre-commit-config.yaml on line 65.
+* [Component]: This is the name of the component, and it should match the directory name where the component code is located.
+
+## Submitting a PR
+
+- [ ] Fork the [esp-protocols repository on GitHub](https://github.com/espressif/esp-protocols) to start making your changes.
+
+- [ ] Install pre-commit hooks: `pip install pre-commit && pre-commit install-hooks && pre-commit install --hook-type commit-msg --hook-type pre-push`
+
+- [ ] Send a pull request (PR) and work with us until it gets merged and published. Contributions may need some modifications, so a few rounds of review and fixing may be necessary.
+
+For quick merging, the contribution should be short, and concentrated on a single feature or topic. The larger the contribution is, the longer it would take to review it and merge it.
+
+Please follow the [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) rule when writing commit messages.
+
+A typical commit message title template:
+
+Template:
+`[type]([scope]): Message`
+
+e.g.
+`feat(console): Added fully operational ifconfig command`
+
+
+## Creating a new component
+Once the commit containing a new component is ready follow the steps below:
+1. Add a file named .cz.yaml to the root of the component and add it to your commit.
+
+The template for .cz.yaml should look like this:
+```
+---
+commitizen:
+  bump_message: 'bump([scope]): $current_version -> $new_version'
+  pre_bump_hooks: python ../../ci/changelog.py [component]
+  tag_format: [component]-v$version
+  version: 0.0.0
+  version_files:
+  - idf_component.yml
+```
+2. Run the following command to bump the version of the component:
+
+`ci/bump [component] [version] --bump-message "bump([scope]): First version [version]"`
+
+Replace [component], [version] and [scope] with the specific component name, version and scope you are working with. This command will help you bump the version of the component with the provided details.
+
+Note: It is crucial to adhere to the above steps when introducing a new component. Never merge the code for a new component without first implementing a bump commit.
+
+## Release process
+
+When releasing a new component version we have to:
+
+* Update the version number
+* Update the changelog
+* Create the version tag in this repository
+* Deploy the component to component registry
+* Update the documentation
+
+This process is not fully automated, the first step needs to be performed manually by project maintainers running the `bump` command. Release procedure is as follows:
+* Run `ci/bump [component] [version]` (version number is optional, `cz` would automatically increment it if not present)
+* Check the updated `CHANGELOG.md` and the generated bump commit message
+* Create a PR
+Once the PR is merged, the CI job tags the merge commit, creates a new release, builds and deploys documentation and the new component to the component registry

+# Modem Simulator Component
+
+A Wi-Fi modem simulator that extends ESP-AT with PPP server capabilities, turning ESP32 into a fully functional Wi-Fi modem. Perfect for testing AT commands and PPP connections without real hardware dependencies.
+
+## What it does
+
+- Extends ESP-AT firmware with PPP server functionality
+- Provides DATA mode for raw IP communication
+- Enables existing communication stacks (MQTT, HTTP, custom protocols) to work over Wi-Fi
+- Ideal for testing ESP-Modem library and CI reliability
+
+## Quick Start
+
+```bash
+cd common_components/modem_sim
+./install.sh
+source export.sh
+idf.py build
+```
+
+## Custom Platform/Module
+
+```bash
+./install.sh PLATFORM_ESP32S3 WROOM-32
+```
+
+## Configuration
+
+The `sdkconfig.defaults` includes:
+- Wi-Fi and Bluetooth enabled
+- PPP server support
+- AT commands for HTTP/MQTT
+- 4MB flash configuration
+
+## Project Structure
+
+```

+## Updating ASIO
+
+ASIO is managed as a submodule, to updated the version first the [espressif](github.com/espressif/asio) ASIO fork must be updated.
+
+## Release process
+
+When releasing a new component version we have to:
+
+* Update the submodule reference
+* Update the version number
+* Update the changelog
+
+And the automation process takes care of the last steps:
+
+* Create the version tag in this repository
+* Deploy the component to component registry
+* Update the documentation
+
+This process needs to be manually handled for ASIO component since commitizen doesn't accept the versioning schema used.
+
+* Increment manually the version in the [manifest file](idf_component.yml)
+* Export environment variables for changelog generation:
+    - CZ_PRE_CURRENT_TAG_VERSION
+    - CZ_PRE_NEW_TAG_VERSION
+    - CZ_PRE_NEW_VERSION
+* Run `python ../../ci/changelog.py asio` from this directory to generate the change log
+* Check the updated `CHANGELOG.md`
+* Commit the changes with the adequated message format.
+    ```
+    bump(asio): $current_version -> $new_version
+
+    $Changelog for the version
+    ```
+* Create a PR
+
+Once the PR is merged, the CI job tags the merge commit, creates a new release, builds and deploys documentation and the new component to the component registry

+# Asio chat client and server examples
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+The application aims to demonstrate a simple use of Asio library in different modes.
+In project settings it could be configured to run either a Asio chat server, a Asio chat client, or both.
+
+## How to use example
+
+The example is configured by default as an Asio chat client.
+
+Note that the example uses string representation of IP addresses and ports.
+
+You can find the upstream asio chat implementation [here] https://github.com/chriskohlhoff/asio/tree/master/asio/src/examples/cpp11/chat
+
+### Asio Client
+
+In the client mode, the example connects to the configured address, sends the message, which was inserted as an input in the terminal, and receives a response.
+
+### Asio Server
+
+In the server mode, Asio chat server with a specified port number is created and being polled till a connection request from the client arrives.
+Chat server echoes a message (received from any client) to all connected clients.
+
+## Configure the project
+
+```
+idf.py menuconfig
+```
+
+Set following parameters under Example Configuration Options:
+
+* Set `EXAMPLE_CHAT_SERVER` to use the example as an ASIO chat server
+    * Configure `EXAMPLE_CHAT_SERVER_BIND_PORT` to the port number.
+
+* Set `EXAMPLE_CHAT_CLIENT` to use the example as an ASIO chat client
+    * Configure `EXAMPLE_CHAT_CLIENT_CONNECT_ADDRESS` to a string representation of the address to connect the client to.
+    * Configure `EXAMPLE_CHAT_CLIENT_CONNECT_PORT` to the port number.
+
+* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more d    etails.
+
+## Running the example in server mode
+
+- Configure the example according "Configure the project" section.
+- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
+- Wait for the board to connect to WiFi or Ethernet (note the IP address).
+- Connect to the server using multiple clients, for example using any option below.
+    - build and run asio chat client on your host machine
+    - run chat_client asio example on ESP platform
+    - since chat messages consists of ASCII size and message, it is possible to
+        netcat `nc IP PORT` and type for example ` 4ABC<CR>` to transmit 'ABC\n'
+
+## Running the example in client mode
+
+- Configure the example according "Configure the project" section.
+- Start chat server either on host machine or as another ESP device running chat_server example.
+- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
+- Wait for the board to connect to WiFi or Ethernet.
+- Receive and send messages to/from other clients on stdin/stdout via serial terminal.
+
+See the README.md file in the upper level 'examples' directory for more information about examples.
