As I'm using MAMP (on mac OS) to run a local server, here's my snippet from httpd.conf to set up an alias (to make Drupal run from http://localhost:8888/my-drupal8/).
MAMP for Windows and mac OS: https://www.mamp.info/en/
Alias /my-drupal8 "/Applications/MAMP/htdocs/my-drupal8/web"
<Directory "/Applications/MAMP/htdocs/my-drupal8/web">
#Options Indexes MultiViews
Options All
AllowOverride All
Order allow,deny
Allow from all
</Directory>
If you clone or download a completed theme directly from this repo, then follow these installation instructions:
Run composer require 'drupal/bootstrap_barrio:^4.22'
command in the root folder of the project.
Gleb theme should be set as default theme
