 Import allows reading a file into the parameter store.
 
 - All parameters from the file must be stored as the same type i.e. String or SecretString etc.
-- Currently only `dotenv` key-value style files are supported. **However** the parsers are already accessible in the code for the other 3 major formats - I just need create a flag to allow a choice of input format.
+- Multiple file formats are supported through the `--format` which is by default set to `dotenv`. Other supported formats include `json`, `toml` and `yaml`. See the table below for an overview.
+- **Only flat data structures are supported currently**

 ## Why?
 I made this tool because although **chamber** is an excellent tool - it uses **viper** underneath and the problem with **viper** is that the keys are **CASE INSENSITIVE** which for me was unacceptable. So I decided to *roll-my-own* using the wonderful [**koanf**](https://github.com/knadh/koanf) library to manage the deserialisation of various config files.
