 ## Description
 
-epp-client is a client library written in Rust for Internet domain registration and management for domain registrars.
+epp-client is a client library written in Rust for Internet domain registration
+and management for domain registrars.
 
-It supports the following basic Domain, Contact, Host, and Message management calls, with plans to add more calls
-and other EPP extensions in the future, and to eventually be RFC compliant with the EPP protocol.

-## Prerequisites
-
-To use the library, you must have an `epp-client/epp-client.toml` config file with the relevant registry
-credentials in your default user configuration directory on your OS. For Linux, this is the `XDG user directory`,
-usually located at `$HOME/.config` or defined by the `XDG_CONFIG_HOME` environment variable.
-
-An example config looks like this:
-
-```toml
-[registry.verisign]
-host = 'epp.verisign-grs.com'
-port = 700
-username = 'username'
-password = 'password'
-# service extensions
-ext_uris = []
-
-[registry.verisign.tls_files]
-# the full client certificate chain in PEM format
-cert_chain = '/path/to/certificate/chain/pemfile'
-# the RSA private key for your certificate
-key = '/path/to/private/key/pemfile'
-```

 ## Operation
 
-Once the config is set correctly, you can create a mut variable of type `EppClient`
-with the domain registry

 ## Request
 
-Currently I don't have access to a registry's OT&E account to do extensive testing. I am using [hexonet's EPP Gateway](https://wiki.hexonet.net/wiki/EPP_Gateway) for testing, but access to a registry's OT&E account would be very helpful, so if anyone could help me out with one I would be very grateful!
