     * Writing test scenarios in Haskell and provides a small testing library with helper functions
-    * Running tests against multiple bazel verions including binary bazel distributions and nixpkgs bazel packages
+    * Running tests against multiple bazel versions including binary bazel distributions and nixpkgs bazel packages
     * Reusing the bazel cache between test runs to significantly speedup test process
