I am new to Magento. I need to override a html file in a project. The project using an extension called 'Amitshree'. I need to override an email template created in this extension in my project. I need a step by step solution because I am not a magento developer. I went through some solutions in this platform, but couldn't resolve my task. The project is developed in Magento 2.
Email templates are located in different modules, let's say you want to override new order template.
Locate the phtml file, in that case
vendor/magento/module_sales/email/order_new.phtml
Copy it to app/design/frontend/[YourCompany]/[Your_Theme]/Magento_Sales/email.
Change whatever you want.
