+Installation for tutor
+**********************
+
+This method works with [tutor](https://github.com/overhangio/tutor).
+
+First, go to your requirements directory:
+
+```sh
+cd $(tutor config printroot)/env/build/openedx/requirements/
+```
+
+add the `chatgpt-xblock` repo to  the `private.txt`:
+
+```sh
+echo "git+https://github.com/edly-io/openedx-cmi5-xblock.git" >> private.txt
+```
+
+and build a new image:
+
+```sh
+tutor images build openedx
+```
+
+In your studio, in your desired course, go to Advanced Settings and add `"openedx_cmi5_xblock"` in the Advanced Module List.
+
+
+Development
+***********
+
+There's no need to build a new image, if you just want to play with the xblock.
+
+First, clone the repo in the requirements directory:
+
+```sh
+cd $(tutor config printroot)/env/build/openedx/requirements/
+git clone [email protected]:edly-io/openedx-cmi5-xblock.git
+```
+
+exec to the lms container and install the XBlock:
+
+```sh
+tutor dev exec -it cms bash
+cd ../requirements
+pip install -e openedx-cmi5-xblock
+```
+
+Note: This is not the best practice to develop an XBlock, but it works if you don't want to build dev image.
