DCE is not constructed as a typical ns-3 extension module (for the contrib directory), but it is also not a fork either. DCE has its own build system (also based on Waf) and links ns-3 libraries from ns-3-dev or an ns-3 release.
Users are strongly recommended to use the [bake build system](https://www.nsnam.org/docs/bake/tutorial/html/) to configure, download, and build DCE.
#### Current installation instructions
DCE releases are made asynchronously with ns-3 releases. The last DCE release is version 1.10, compatible with ns-3.28. A new release 1.11 is in preparation to coincide with ns-3.31. In the meantime, users are suggested to use the development tree version with ns-3.30 release or with ns-3-dev.
Please read the [DCE manual](https://www.nsnam.org/docs/dce/manual/singlehtml/index.html) for detailed installation instructions.
