The wrocnet.org website – Wrocław .NET User Group.

Built with Jekyll and the Minimal Mistakes theme.

1. Install Ruby via Homebrew (the system Ruby is too old):

   brew install ruby
   export PATH="$(brew --prefix ruby)/bin:$PATH"

   Add the export PATH line to your ~/.zshrc to make it permanent.

2. Install Bundler and dependencies:

   gem install bundler
   bundle install

3. Start the dev server:

   bundle exec jekyll serve --livereload

1. Install Ruby via RubyInstaller for Windows (choose the Ruby+Devkit version ≥ 3.0). Run the ridk install step at the end of the installer.

2. Open a new Command Prompt or PowerShell window and install dependencies:

   gem install bundler
   bundle install

3. Start the dev server:

   bundle exec jekyll serve --livereload

The site will be available at http://localhost:4000.

To run the same checks as CI before opening a PR:

Prerequisite for step 1: install yamllint (for example: python -m pip install yamllint).

1. Lint YAML files:

   yamllint -c .yamllint _data _config.yml

2. Build Jekyll in strict front matter mode:

   bundle exec jekyll build --strict_front_matter

3. Validate generated HTML, internal links, and images:

   bundle exec htmlproofer ./_site --disable-external --no-enforce-https
