Config file from $HOME/.tfdocs.d/ is not picked up

[papanito]

Describe the bug

I have a config file in $HOME/.tfdocs.d/

ls -a $HOME/.tfdocs.d/
./  ../  .terraform-docs.yml`

However, when I run terraform-docs without -c it does not seem to pick the file up

terraform-docs . 
A utility to generate documentation from Terraform modules in various output formats

Usage:
  terraform-docs [PATH] [flags]
  terraform-docs [command]
...

It works fine if the config file is in the root of the module.

How can we reproduce it?
