+We are very happy to announce the initial release of `ortac-core`,
+ortac-runtime` and `ortac-qcheck-stm`.
+
+Ortac is a runtime assertion checking tool for OCaml based on Gospel
+specification language.
+
+`ortac-core` package exposes a library to translate a subset of Gospel
+specification language into OCaml terms. It also provides the `ortac`
+command-line tool. You will need to have one of Ortac plugins installed to use
+the `ortac` command-line tool.
+
+`ortac-runtime` provides runtime environment that the translated terms depend
+on. In particular, it provides an implementation of the executable subset of
+the Gospel standard library.
+
+`ortac-qcheck-stm` provides a plugin for Ortac. It generates QCheck-STM
+sequential tests for a module specified with Gospel. QCheck-STM is a
+model-based testing framework and Ortac/QCheck-STM relies on the Gospel models
+you gave in the specifications to build the QCheck-STM tests. See the
+[documentation](https://ocaml-gospel.github.io/ortac/ortac-qcheck-stm/index.html)
+for more details on how to write the specifications and how to ues the tool to
+test your libraries.
