Two websites which can help in improving README of your Github projects are as follows:-

1.Socialify(github.com/wei/socialify):
Socialify allows us to create a beautiful project image based on languages used in our project. There are a lot of customisation options and this can very well replace the usual title and description in projects.

Once generated, you can download the image as a .png, .jpeg or .webp and use it in the README file of your project.

Here is a sample preview of the image I used in one of my own projects:-

2.Shields io (github.com/badges/shields):
Sheilds io can be used to add small badges in SVG format just below project image for giving info about project files, social handles, licence information, code test coverage among a lot of other options as well.

The website supports dozens of continuous integration badges, package registries, distributions, app stores, social networks, code coverage badges, and code analysis badges as well.

There are a few secondary websites listed on the Github repo from which you can generate other types of badges.

You can also add few project screenshots or make a GIF out of screen recording of your project to improve your project README even further.

Hope this short article was useful to you all. Have a nice day ahead.
