+# TUF implementations
+
+We list open source implementations of TUF in several languages, along with links to project code and documentation. This list is not an endorsement of any project, but rather a resource for interested users and contributors. It excludes the various closed-source implementations of the project. If there is an implementation or piece of documentation missing from this list, please open a pr on this repository to update it.
