 `xdrgen` is a code generator that takes XDR IDL files (`.x` files) as specified

+Xdrgen is a relatively stable library and major changes have not been made to
+it for sometime.
 
 Aside from the test fixtures in [spec/fixtures](spec/fixtures), the only .x
 files that have been tested with it are the .x files used for the [Stellar
 protocol](https://github.com/stellar/stellar-xdr).
 
-If you're building a new code generator, the preferred way to provide a code
-generator to xdrgen is to use it as a library. See below for examples for how
-to do so.

+> **Generators are no longer maintained in this repository.**

+> If you're building a code generator, use xdrgen as a library (see below).

+> Generators that were previously included (Python, Java, Rust) have been moved

-Xdrgen has support for built-in generators via the CLI's `-l` option, but they
-are not maintained, not tested, and are preserved for legacy usage.
+The CLI still has the following built-in generators:
 
-- ruby: complete support
-- javascript: complete support
-- golang: currently using a fork of go-xdr, but has complete support
-- elixir: support is experimental as the SDK is in early development. Generated
-  code requires [:exdr](https://github.com/revelrylabs/exdr) in your deps
-- C#: complete support

-Instead of contributing new generators to this repository, use xdrgen as a
-library and maintain the generator independently where you can test and
-maintain it.
