 In addition to the dependencies listed in each crate's `Cargo.toml`, the project bundles a few external dependencies such as `tmc-checkstyle-runner`, `tmc-junit-runner` and so on. When updating dependencies, you may want to check whether these projects have been updated.
 
+For convenience, a tool called [cargo-outdated](https://crates.io/crates/cargo-outdated) can be installed to automatically check all the crates in the workspace for outdated dependencies. You may want to call `cargo update` first to update dependencies to the latest semver-compatible version.

 ## Versioning
 
 tmc-langs-rust follows Rust-style semantic versioning, but only for the `tmc-langs-cli` and `tmc-langs` crates. Other crates may go through breaking changes in any release as long as the CLI and langs are unaffected.
