### Setup:

The project is build over `jekyll` and `ruby`

Ruby setup is complex on macbook so it is recommended to use `rbenv` or `rvm` to manage ruby versions.

Check GitHub pages supported ruby versions [here](https://pages.github.com/versions/).

1. Install `rbenv`

   ```shell

   brew install rbenv

   ```

2. Install ruby latest version

   ```shell

   rbenv install 3.3.4

   ```

3. Set the local ruby version for the project

   ```shell

    rbenv local 3.3.4

    ```

4. Add rbenv ruby path to your shell configuration file (e.g., `~/.bashrc`, `~/.zshrc`)

   ```shell

   echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

   echo 'eval "$(rbenv init -)"' >> ~/.bashrc

   source ~/.bashrc

   ```

To start the project

1. Install bundles using

   ```shell

   bundle install

   ```

2. Serve the website (using local bundle files)

   ```shell 

   bundle exec jekyll serve

   ```
