 in order to determine if there is any similarity between them, preventing you from using a potentially illegitimate one.

+In short, `Twyn` protects you against [typosquatting attacks](https://en.wikipedia.org/wiki/Typosquatting).
 
 It works as follows:
 
 1. Either choose to scan the dependencies in a dependencies file you specify (`--dependency-file`) or some dependencies introduced through the CLI (`--dependency`). If no option was provided, it will try to find a dependencies file in your working path.
 2. If the name of your package name matches with the name of one of the most well known packages, the package is accepted.
-3. If the name of your package is similar to the name of one of the most used packages, Twyn will prompt an error.
-4. If your package name is not in the list of the most known ones and is not similar enough to any of those to be considered misspelled, the package is accepted. Twyn assumes that you're using either a not so popular package (therefore it can't verify its legitimacy) or a package created by yourself, therefore unknown for the rest.
