 So, pm-convert will just raise actual data up on top level and write into disk.
 
-## Settings file
-
-You may want to specify parameters once and just use them everytime without explicit defining arguments to `pm-convert`.
-
-This might be done in several ways.
-
-1. Save this file as `pm-convert-settings.json` in your project directory:
-
-   ```json
-   {
-       "directories": [],
-       "files": [],
-       "environment": "",
-       "output": "",
-       "preserveOutput": false,
-       "formats": [],
-       "vars": {}
-   }
-   ```
-   
-   Fill it with values you need.
-
-2. Add `--dump` at the end of your command and all arguments you provided will be converted and saved as
-   `pm-convert-settings.json` in your curent working directory. For example in `--help` file will contain this:
-
-   ```json
-   {
-       "directories": [
-           "~/team",
-           "~/personal"
-       ],
-       "files": [
-           "~/dir1/first.postman_collection.json",
-           "~/dir2/second.postman_collection.json"
-       ],
-       "environment": "~/localhost.postman_environment.json",
-       "output": "~/postman_export",
-       "preserveOutput": false,
-       "formats": [
-           "http",
-           "curl",
-           "wget",
-           "v2.0",
-           "v2.1"
-       ],
-       "vars": {
-           "myvar": "some value"
-       }
-   }
-   ```
-
-   If settings file already exists then you will be asked what to do: overwrite it, back it up or exit.
-
-Once settings file saved in current you can just run `pm-convert`.
-Settings will be applied like if you pass them explicitly via arguments.
-
 ## How to implement a new format
 
 1. Create new namespace in `./src/Converters` and name it according to format of your choice.
