 #### Self-signed SSL certificates (via _localhost_ gem, for development use): 
 
-Puma supports [localhost](https://github.com/socketry/localhost) gem for self-signed certificates. This is particularly useful if you want to use Puma with SSL locally, and self-signed certificates will work for your use-case. Currently, `localhost-authority` can be used only in MRI. To use [localhost](https://github.com/socketry/localhost), you have to `require "localhost/authority"`:
