+Key Features
+============
 
-Note: Aspects is beta and not yet production ready! Please feel free to experiment with the system and offer feedback about what you'd like to see by adding Issues in this repository. Current details on the beta progress can be found here: https://openedx.atlassian.net/wiki/spaces/COMM/pages/3861512203/Aspects+Beta
+- Streamlined deployment of analytics and reporting tools.
+- Integration with Open edX for real-time and historical data analytics.
+- Extensible architecture supporting customization.
 
-Compatibility
--------------
-
-This plugin is compatible with Tutor 15.0.0 and later and is expected to be compatible with Open edX releases from Nutmeg forward.
-
-Installation
-------------
-
-Aspects is implemented as a Tutor plugin. Documentation will be coming soon to cover how to install Aspects in non-Tutor environments, but by far the easiest way to try and install it is via Tutor. These instructions assume you are running a `tutor local` install, which is the fastest and easiest way to get started.
-
-#. Install Tutor: https://docs.tutor.overhang.io/install.html#install
 
-#. Create an admin user on the LMS: https://docs.tutor.overhang.io/whatnext.html#logging-in-as-administrator
 
-#. Install the Aspects plugin (in your Tutor Python environment)::
+.. note::
+Aspects is currently in beta and not production-ready. Feedback and contributions are welcome through GitHub Issues.
 
-    pip install tutor-contrib-aspects
-
-#. Enable the plugins::
-
-    tutor plugins enable aspects
-
-#. Save the changes to the environment::
-
-    tutor config save
-
-#. Because we're installing new applications in LMS (event-routing-backends, event-sink-clickhouse) you will need to rebuild your openedx Docker image::
+Compatibility
+=============
 
-    tutor images build openedx --no-cache
+The plugin is compatible with Tutor 15.0.0 and later and supports Open edX releases from Nutmeg onward.
 
-#. Build the Aspects-flavored Superset image to bake your settings (such as database passwords) into the Superset assets::
+Installation
+============
 
-    tutor images build aspects-superset
+Aspects is implemented as a Tutor plugin. For now, the easiest installation method is via Tutor. Follow these steps for a ``tutor local`` installation:
 
-#. Run the initialization scripts::
+1. **Install Tutor**:
+   Follow the instructions at `Tutor Installation Guide <https://docs.tutor.overhang.io/install.html#install>`_.
 
-    tutor local do init
+2. **Create an Admin User**:
+   Refer to the `Tutor Setup Guide <https://docs.tutor.overhang.io/whatnext.html#logging-in-as-administrator>`_.
 
-At this point you should have a working Tutor / Aspects environment, but with no way to create data! There are a few options for how to proceed.
+3. **Install and Enable the Plugin**:
 
-#. If you would just like to see some data populated in the charts without loading a real course in the LMS you can create test data in the database (use ``--help`` for usage)::
+   .. code-block:: bash
 
-        tutor local do load-xapi-test-data
+      pip install tutor-contrib-aspects
+      tutor plugins enable aspects
+      tutor config save
 
-#. OR Load the test course and generate real data from the LMS:
+4. **Rebuild Docker Images**:
 
-   #. https://docs.tutor.overhang.io/whatnext.html#importing-a-demo-course
+   .. code-block:: bash
 
-   #. Log into the LMS with your admin user and enroll / proceed through the demo course
+      tutor images build openedx --no-cache
+      tutor images build aspects-superset
 
-#. OR If you are adding Aspects to an existing LMS that already has data
+5. **Initialize the Environment**:
 
-   #. Sink course data from the LMS to clickhouse (see https://github.com/openedx/openedx-event-sink-clickhouse for more information)::
+   .. code-block:: bash
 
-       tutor local do dump-data-to-clickhouse --options "--object course_overviews"
+      tutor local do init
 
-   #. Sink Historical event data to ClickHouse::
+Data Population Options
+------------------------
 
-       tutor [dev|local] do transform-tracking-logs \
-         --source_provider LOCAL --source_config '{"key": "/openedx/data", "container":
-            "logs", "prefix": "tracking.log"}' \
-         --transformer_type xapi
+To visualize data:
 
-       # Note that this will work only for default tutor installation. If you store your tracking logs any other way, you need to change the source_config option accordingly.
-       # See https://event-routing-backends.readthedocs.io/en/latest/howto/how_to_bulk_transform.html#sources-and-destinations for details on how to change the source_config option.
+- Generate test data:
 
-#. If your assets have changed since the last time you ran init, you will need to rebuild the aspects-superset image and re-import the assets::
+  .. code-block:: bash
 
-    tutor images build aspects-superset --no-cache
-    tutor local do import-assets
+     tutor local do load-xapi-test-data
 
-#. Make sure to build and push your Superset image in the following cases:
+- Import a demo course and create real data:
 
-   #. If you have made changes to the Superset assets.
-   #. If you have made changes to the Clickhouse/DBT schema.
-   #. If you are using custom translations.
+  Follow `these steps <https://docs.tutor.overhang.io/whatnext.html#importing-a-demo-course>`_.
 
+- Sync data from an existing LMS:
 
-You should now have data to look at in Superset! Log in to https://superset.local.overhang.io/ with your admin account and you should see charts with your data.
+  .. code-block:: bash
 
-Aspects Autoscaling
--------------------
+     tutor local do dump-data-to-clickhouse --options "--object course_overviews"
+     tutor [dev|local] do transform-tracking-logs --source_provider LOCAL --source_config '{"key": "/openedx/data", "container": "logs", "prefix": "tracking.log"}' --transformer_type xapi
 
-Aspects adds default autoscaling values for `Ralph`, `Superset` and the `Superset Worker` deployments via
-`tutor-contrib-pod-autoscaling <https://github.com/eduNEXT/tutor-contrib-pod-autoscaling>`_. To apply the
-autoscaling settings make sure to install the plugin and enable it. To modify the autoscaling values
-see the `Configuration <https://github.com/eduNEXT/tutor-contrib-pod-autoscaling?tab=readme-ov-file#configuration>`_ section.
+Superset and Autoscaling
+=========================
 
 Superset Assets
 ---------------
 
-Aspects maintains the Superset assets in this repository, specifically the dashboards,
-charts, datasets, and databases. That means that any updates made here will be reflected
-on your Superset instance when you update your deployment.
-
-But it also means that any local changes you make to these assets will be overwritten
-when you update your deployment. To prevent your local changes from being overwritten,
-please create new assets and make your changes there instead. You can copy an existing
-asset by editing the asset in Superset and selecting "Save As" to save it to a new name.
-
-# Note: If you are using custom assets you will need to rebuild your aspects-superset
-# image on your local machine with `tutor images build aspects-superset --no-cache`.
-
-Assets (charts/datasets) created for Aspects that are no longer used can be listed in 
-`aspects_asset_list.yaml`. These assets & any translated assets created from them, 
-are deleted from Superset during `init` (specifically `import-assets`). The corresponding 
-YAML files are deleted during `import_superset_zip` or and `check_superset_assets`.
-
-Sharing Charts and Dashboards
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To share your charts with others in the community, use Superset's "Export" button to
-save a zip file of your charts and related datasets.
-
-.. warning::
-    The exported datasets will contain hard-coded references to your particular
-    databases, including your database hostname, port, and username, in some cases
-    it may also contain database passwords. It is vital that you review the
-    database and dataset files before sharing them.
-
-To import charts or dashboards shared by someone in the community:
-
-#. Expand the zip file and look for any files added under ``databases``.
-   Update the ``sqlalchemy_uri`` to match your database's connection details.
-#. Compress the files back into a ``.zip`` file.
-#. On the Charts or Dashboards page, use the "Import" button to upload your ``.zip`` file.
-
-
-Contributing Charts and Dashboards to Aspects
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The Superset assets provided by Aspects can be found in the templated
-`tutoraspects/templates/aspects/build/aspects-superset/openedx-assets/assets/` directory. For the most part,
-these files are what Superset exports, but with some crucial differences
-which make these assets usable across all Tutor deployments.
+Aspects maintains its Superset assets (dashboards, charts, datasets) in the repository. Local changes to these assets will be overwritten during updates unless saved as new assets.
 
-To contribute assets to Aspects:
+To rebuild and re-import assets:
 
-#. Fork this repository and have a locally running Tutor set up with this plugin
-   installed.
-#. Export the assets you want to contribute as described in `Sharing Charts and Dashboards`
-#. Run the command:
-   `tutor aspects import_superset_zip ~/Downloads/your_file.zip`
-#. This command will copy the files from your zip to the assets directory and
-   attempt to warn you if there are hard coded connection settings where it expects
-   template variables. These are usually in database and dataset assets, and those are
-   often assets that already exist. The warnings look like:
+.. code-block:: bash
 
-   `WARN: fact_enrollments.yaml has schema set to reporting instead of a setting.`
-#. Check the diff of files and update any database connection strings or table names
-   to use Tutor configuration template variables instead of hard-coded strings, e.g.
-   replace ``clickhouse`` with ``{{CLICKHOUSE_HOST}}``. Passwords can be left as
-   ``{{CLICKHOUSE_PASSWORD}}``, though be aware that if you are adding new
-   databases, you'll need to update ``SUPERSET_DB_PASSWORDS`` in the init scripts.
-   Here is the default connection string for reference::
+   tutor images build aspects-superset --no-cache
+   tutor local do import-assets
 
-   ``clickhousedb+connect://{{CLICKHOUSE_REPORT_URL}}``
-#. You will likely also run into issues where our SQL templates have been expanded into
-   their actual SQL. If you haven't changed the SQL of these queries (stored in
-   `tutoraspects/templates/openedx-assets/queries` you can just revert that change back
-   to their `include` values such as:
-   `sql: "{% include 'openedx-assets/queries/fact_enrollments_by_day.sql' %}"`
-#. The script will also warn about missing `_roles` in dashboards. Superset does not export
-   these, so you will need to manually add this key with the roles that are necessary to
-   view the dashboard. See the existing dashboards for how this is done.
-#. Re-build your ``aspects-superset`` image with `tutor images build aspects-superset --no-cache`
-#. Run the command `tutor aspects check_superset_assets` to confirm there are no
-   duplicate assets, which can happen when you rename an asset, and will cause import
-   to fail. The command will automatically delete the older file if it finds a duplicate.
-#. Check that everything imports correctly by running `tutor local do import-assets`
-   and confirming there are no errors.
-#. Double check that your database password did not get exported before committing!
-#. Commit and submit a PR with screenshots of your new chart or dashboards, along with an
-   explanation of what data question they answer.
+Autoscaling
+-----------
 
+Aspects supports autoscaling configurations for Ralph, Superset, and Superset Worker via the `Pod Autoscaling plugin <https://github.com/eduNEXT/tutor-contrib-pod-autoscaling>`_. Modify autoscaling settings as needed.
 
-Virtual datasets in Superset
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Contributing Charts and Dashboards
+===================================
 
-Superset supports creating virtual datasets, which are datasets defined using a SQL query instead of mapping directly to an underlying database object. Aspects leverages virtual datasets, along with `SQL templating <https://superset.apache.org/docs/installation/sql-templating/>`_, to make better use of table indexes.
+To contribute Superset assets:
 
-To make it easier for developers to manage virtual datasets, there is an extra step that can be done on the output of ``tutor aspects serialize``. The ``sql`` section of the dataset yaml can be moved to its own file in the `queries`_ directory and included in the yaml like so:
+1. Fork this repository and set up a local Tutor instance with Aspects installed.
+2. Export the desired assets using Superset’s “Export” feature.
+3. Use the command:
 
-.. code-block:: yaml
+   .. code-block:: bash
 
-   sql: "{% include 'openedx-assets/queries/query.sql' %}"
+      tutor aspects import_superset_zip ~/Downloads/your_file.zip
 
+4. Update database connection strings to use template variables.
+5. Validate and rebuild:
 
-However, please keep in mind that the assets declaration is itself a jinja template. That means that any jinja used in the dataset definition should be escaped. There are examples of how to handle this in the existing queries, such as `dim_courses.sql`_.
+   .. code-block:: bash
 
-.. _queries: tutoraspects/templates/openedx-assets/queries/
+      tutor images build aspects-superset --no-cache
+      tutor aspects check_superset_assets
+      tutor local do import-assets
 
-.. _dim_courses.sql: tutoraspects/templates/openedx-assets/queries/dim_courses.sql
+6. Submit a pull request with screenshots and details of your contributions.
 
+Release Workflow
+================
 
-Releasing tutor-contrib-aspects
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Releases are handled via GitHub Actions:
 
-Changelog, package version, PyPI release, and image building are all handled via manually triggered Githib Actions.
+- Trigger the **Bump version and changelog** action to update the version and changelog.
+- Merge the PR to initiate the **release** and **build-image** workflows.
 
-To trigger a build you must have access to manually trigger the "Bump version and changelog" action. This will update the version and changelog in a new PR. If the PR looks good, you can approve and merge it. Merging this PR will:
+Ensure the updated version appears on `PyPI <https://pypi.org>`_ and DockerHub.
 
-- Trigger the "release" workflow which will tag a Github release with the new version number, and then push the release to PyPI
-- Trigger the "build-image" workflow, which builds our images for aspects, aspects-superset, and openedx to the EduNEXT DockerHub repositories
+Additional Resources
+=====================
 
-When the workflows are finished you should confirm that you see the new version on PyPI and images in DockerHub.
