-//! This program is a constrained file/FD server to serve file requests through a remote[1] binder
+//! This program is a constrained file/FD server to serve file requests through a remote binder
 //! service. The file server is not designed to serve arbitrary file paths in the filesystem. On
 //! the contrary, the server should be configured to start with already opened FDs, and serve the
 //! client's request against the FDs
 //!
 //! For example, `exec 9</path/to/file fd_server --ro-fds 9` starts the binder service. A client
 //! client can then request the content of file 9 by offset and size.
-//!
-//! [1] Since the remote binder is not ready, this currently implementation uses local binder
-//!     first.
