Luma theme changes but need a child theme?

[Lightme]

Hi, 

I have a question my Luma theme is under 'vendor' and not under 'app/design/frontend' that last one is basicly empty. But I read tutorials that I need Luma as a parent theme but it isn't in the same folder as suggest. 

Where I go for from here?

Hello @Lightme 

You need to create child theme of luma by following below steps:

Create app/design/frontend/ThemeName/theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../lib/internal/Magento/Framework/Config/etc/theme.xsd">
  <title>Luma Child</title>
  <parent>Magento/luma</parent>
</theme>

app/design/frontend/ThemeName/
├── simple/
│   ├── etc/
│   │   ├── view.xml
│   ├── web/
│   │   ├── images
│   │   │   ├── logo.svg
│   ├── registration.php
│   ├── theme.xml
│   ├── composer.json

Now override luma theme with specific file path and customise as per requirement.

It may help you!
Thank you.

Hi, 

Thank you for your time to awnser my question but the main is in "root/vendor/" so how do I in 

  <parent>Magento/luma</parent>

Set the correct path to there? Just <parent>vendor/luma/</parent> (something like that)
