+
+### Workshop Code & C++ basic environment
+- Source Code (This repository. Git Clone it to your local machine or get files from your instructor.)
+- [CMake](https://cmake.org/download/)
+- [Make](https://www.gnu.org/software/make/)
+- [GCC](https://gcc.gnu.org/) (or [Clang](https://clang.llvm.org/))

+## Enable GitHub Copilot Extension
+- Install [VSCode GitHub Copilot Extension](vscode:extension/GitHub.copilot) (or [JetBrains IDE GitHub Copilot Plugin](https://plugins.jetbrains.com/plugin/20772-github-copilot))
+- Setup netowrking (if neccessary) (Reference: [Configuring your proxy server or firewall for Copilot](https://docs.github.com/en/enterprise-cloud@latest/copilot/managing-copilot/managing-github-copilot-in-your-organization/configuring-your-proxy-server-or-firewall-for-copilot))
+- Sign in to GitHub Copilot Extension with your GitHub account
+
+## Verification
+### GitHub Copilot is Enabled
+- Make sure the Extension is enabled by checking the status bar at the bottom of the VSCode window.
+
+
+### Build environment
+Run the following two commands to prepare the make file and then build the project. You can run the following commands in your terminal or in VSCode Terminal.
+```bash
+cmake -S . -B build
+cmake --build build
+```

+# GitHub Copilot C++ Workshop
+
+ [:jp: Japanese](README.md) | [:us: English](README.md)
+
+This is a hands-on workshop to demonstrate the usage of the [GitHub Copilot](https://github.com/features/copilot).
+
It is a CLI tool that allows users to convert between units of different types.
+
+## Getting Started
+### Build
+Run the following two commands to prepare the make file and then build the project:
+```bash
+cmake -S . -B build
+cmake --build build
+```
+### Run & Test
+- To run the main program:
+ ```bash
+ ./build/main
+ ```
+- To execute the tests:
+ ```bash
+ /build/run-tests
+ ```
+### Run as VSCode Tasks
+The above commands are also all defined as tasks in the `.vscode/tasks.json` file. You can run them from the VSCode Task Runner from Command Palette (cmd+shift+p or ctrl+shift+p) and typing `Run Task`.:
+
+| Task | Description |
+| ------------------- | ----------------------------------------------------------------------------------------------------------------- |
+| `prepare` | Runs `cmake -S . -B build` command. You most likely won't have to run this command manually, use `build` instead. |
+| `build` | Runs `Prepare` followed by `cmake --build build` command |
+| `clean:build` | Same as `Build`, but Removes the directory before executing the Build step |
+| `Start Application` | Runs the `./build/main` command |
+| `Run Tests` | Runs the `./build/run-tests` command |
+
+## Hands On
+- [ ] Finish the `Distance` Conversion Class and include it in the `main.cpp` (optionally, first implement tests and do a TDD appraoch)
+- [ ] Add some Tests for the `Distance::convertDistance`
+- [ ] Refactor all `printf` and `scanf` and use `std::cout` and `std::cin` instead
+- [ ] Add a new Conversion Class for `Weight` to convert in between Kilos and Pounds
+- [ ] Find any issue and fix the issue with the help of Copilot
+- [ ] Add new feature with your ideas with the help of Copilot
