Table of content is not in project's readme.md

Content & configuration

Swagger/OpenAPI definition:

# your YAML here

Swagger-Client usage:

SwaggerClient({
  // your config options here
})

Is your feature request related to a problem?

There is no table of content in the project's main readme.md file. This should be there to help easily navigate the readme.md file.
I also noticed a "mistake" in the "runtime" section of the readme file. It was not treated as a proper section.

Describe the solution you'd like

Adding a table of contents to the readme.md file makes reading it more convenient as navigating to required section becomes easier.

Describe alternatives you've considered

I will create a pull request adding the table of contents within the readme file
