+Migrate test harness to a separate repository
+====
+
+The document describes steps required to move a test harness from ``bowtie`` repository
+to a dedicated repository (e.g. `kotlin-kmp-json-schema-validator <https://github.com/bowtie-json-schema/kotlin-kmp-json-schema-validator>`_).
+
++++++
+Create dedicated repository
++++++
+
+First of all, you need to create a dedicated repository for the test harness.
+The repository can be created using the template repository: TBD.
+// TODO(optimumcode): create a template repository
+
+**The repository name MUST exactly match the test harness name in bowtie**.
+
+If you are a member of `Bowtie <https://github.com/bowtie-json-schema>`_ organization
+you can create a new repository directly in the organization.
+If you are not a member of the organization you can create the repository under your profile
+and once the test harness is migrated, you can move a repository to the **Bowtie** organization
+(kindly create a task for that in `bowtie <https://github.com/bowtie-json-schema/bowtie/issues/new/choose>`_ project).
+
+++++
+Move the test harness to a new repository
+++++
+
+We want to preserve the git history for a test harness.
+To achieve that, we use `git-filter-repo <https://github.com/newren/git-filter-repo>`_.
+Ensure you have `python and git versions <https://github.com/newren/git-filter-repo?tab=readme-ov-file#prerequisites>`_
+compatible with the ``git-filter-repo``.
+
+If you use ``pipx`` you can install it using the following command ::
+
+    pipx install git-filter-repo==v2.45.0
+
+NOTE: there were some issues with the latest version 2.47.0.
+It should be `fixed <https://github.com/newren/git-filter-repo/commit/4697eeb37b7c3c30b0492e344f6b89f7139cef26>`_ in the next version.
+
+Once ``git-filter-repo`` is installed, we can proceed with moving the test harness:
+
+#. Copy bowtie and newly created repository to you local machine;
+#. Create an environment variable containing the test harness name ::
+
+    TEST_HARNESS=<test harness name>
+    # e.g.
+    # TEST_HARNESS=kotlin-kmp-json-schema-validator
+
+#. Execute the following command to copy the git history related to the test harness
+   to a new repository ::
+
+    git-filter-repo --refs main \
+     --source ./bowtie/ \
+     --target ./$TEST_HARNESS/ \
+     --subdirectory-filter implementations/$TEST_HARNESS/ \
+     --refname-callback '
+      # Change e.g. refs/heads/master to refs/heads/prefix-master
+      rdir,rpath = os.path.split(refname)
+      return rdir + b"/bowtie-" + rpath'
+
+#. After the previous command, the new test harness repo will have two branches:
+
+   * main - default repository branch
+   * bowtie-main - branch containing the history from bowtie repository
+
+   Those branches does not have anything in common and git will not allow merging them by default.
+   Switch to the main branch in the new test harness repository and execute the following command ::
+
+    git merge --allow-unrelated-histories bowtie-main
+
+#. Move pre-commit and dependabot configurations specific to the test harness from bowtie repository to new test harness repository.
+   Commit those changes to the main branch.
+
+#. Enable QEMU (if test harness does not support cross-arch compilation) or disable it (if test harness supports cross-arch compilation). TBD.
+
+#. Add a ``.gitignore`` file if needed.
+
+#. Push the main branch to the remote repository
+
+++++
+Remove test harness from bowtie repository
