-Edit your `Cargo.toml` and find and replace `minitrace` with `fastrace` in the source code:
+# minitrace has become [fastrace](https://github.com/fastracelabs/fastrace)!
+
+We decide to continue the development of minitrace under a new organization structure for better community governance.
+
+[fastrace](https://github.com/fastracelabs/fastrace) is maintained by the same maintainers of minitrace, so that we encourage all users to just migrate.
+
+Meanwhile, minitrace will not be maintained any more. See https://github.com/tikv/minitrace-rust/issues/229 for details.
+
+## Migrate to fastrace
+
+Simply substitute the occurance of `minitrace` with `fastrace` in your source code, like:
