Grav CMS on Windows

I installled grav from composer. copied the select2 doc folder from git repository to users folder on my grav cms installation When I open it on localhost it shows like the attached image. What am I doing wrong

As a security measure, Grav 1.7 has enabled Twig function 'autoescape' by default. That means all output (stylesheets tags, scripts tags, content, etc.) are being escaped to prevent malicious code to run.

There are a few options to fix or workaround this:

• If you feel comfortable with code, you can go through all templates provided by the theme used and add filter |raw to output statements of which you are sure the data is safe. Eg. {{ content | raw }}, {{ assets.css() | raw }}, {{ assets.js() | raw }}, etc.
• Or you can add the following settings to user/config/system.yaml to disable auto-escaping:

  twig:
    autoescape: false
  strict_mode:
    twig_compat: true
  

Note: As said, auto-escaping is a security measure, which makes option 2. only advisable as temporary solution until all templates have been fixed as mentioned in option 1.
