Can't fix few things in Tailwind theme

I have created a new website with the Tailwind theme. I am new to Hugo and the documentation for the theme is very limited. I am trying to change the logo but there is no instructions on how to do it. Can someone help me with it?

Also I am encountering an issue when I actually try to create blog posts. Because of the in-built TOC (Table of Content) feature the content gets duplicated and I don’t know how to deal with it. I’d appreciate any help

Read the theme’s read.me file on Github on how to set basic things. For example, to change the logo, add the code below to your configuration file and edit to your liking.

[params.header]
    logo = "logo.webp"

See the requesting help guidelines.

@Arif I read the readme.md file. I changed that logo value to the name of an image I have and nothing changed moreover it does not say where I need to store that image
