+Tutor devstack setup guide
+--------------------------
+
+This is a temporary guide to use this with the experimental Typesense search backends developed for Open edX.
+The backends are found at the following pull requests:
+
+- Forum search: https://github.com/openedx/forum/pull/225
+- Course content and course overview search: https://github.com/openedx/edx-search/pull/222
+
+To begin, install `Tutor Main <https://docs.tutor.edly.io/tutorials/main.html#main>`_, prepare a directory for the new devstack, and cd to it.
+Then you can follow these steps:
+
+.. code-block:: bash
+
+    # Enable the Typesense Tutor plugin
+    git clone https://github.com/open-craft/tutor-contrib-typesense
+    pip install -e ./tutor-contrib-typesense
+    tutor plugins enable typesense
+
+    # Enable the forum and mount the custom branch of forum
+    tutor plugins enable forum
+    git clone https://github.com/open-craft/forum.git
+    git -C ./forum checkout samuel/typesense-backend
+    tutor mounts add ./forum
+
+    # Mount the custom branch of edx-search
+    git clone https://github.com/open-craft/edx-search.git
+    git -C ./edx-search checkout typesense
+    tutor mounts add ./edx-search
+
+    # Launch the devstack
+    tutor images build openedx-dev
+    tutor dev launch
+
+    # Initialise the courseware indexes (forum is initialised automatically)
+    tutor dev exec lms ./manage.py lms shell -c "import search.typesense; search.typesense.delete_indexes(); search.typesense.create_indexes()"
+
+    # Continue with normal set up - eg. create a user, import a course
+    tutor dev do createuser --staff --superuser admin admin@example.com --password password
