 ## Editing documentation
 Documentation can be edited by simply editing the markdown files in the `docs` folder and creating a pull request.
 
 End users can edit the docs by simply clicking the edit button (the pencil icon) on the top of every documentation page. It will open up an editing page on [GitHub](https://github.com/) (you do need to be logged in on GitHub). When you are done, add a small message explaining the change and click 'commit changes'. On the next page, just launch the pull request. We will then review it and approve the changes, or discuss them if necessary.

 ## Deployment
 The documentation is hosted on GitHub pages.
 
-To deploy the documentation, you need to have MkDocs and MkDocs-Material installed, and then run `mkdocs gh-deploy` in the top directory (with the `mkdocs.yml` file).

+## Documentation
+
+Documentation of OpenML consists of the general information pages, such as these, that include common concepts.
+Additionally, each software package such as the Python, Java, and R connectors has their own documentation.
+For convenience, those documentation pages are also available through this common documentation portal.
+
+We always value contributions to our documentation. If you notice any mistake in these documentation pages, click the :material-pencil: button (on the top right). It will open up an editing page on [GitHub](https://github.com/) (you do need to be logged in). When you are done, add a small message explaining the change and click 'commit changes'.

 ## General Documentation
-High-quality and up-to-date documentation are crucial. If you notice any mistake in these documentation pages, click the :material-pencil: button (on the top right). It will open up an editing page on [GitHub](https://github.com/) (you do need to be logged in). When you are done, add a small message explaining the change and click 'commit changes'. On the next page, just launch the pull request. We will then review it and approve the changes, or discuss them if necessary.
 
 The sources are generated by [MkDocs](http://www.mkdocs.org/), using the [Material theme](https://squidfunk.github.io/mkdocs-material/).
 Check these docs to see what is possible in terms of styling.
 
-OpenML is a big project with multiple repositories. To keep the documentation close to the code, it will always be kept in the relevant repositories (see below), and 
+OpenML is a big project with multiple repositories. 
+To keep the documentation close to the code, it will always be kept in the relevant repositories (see below), and 
 combined into these documentation pages using [MkDocs multirepo](https://github.com/jdoiro3/mkdocs-multirepo-plugin/issues/3).
 
-!!! note "Developer note"
-    To work on the documentation locally, do the following:
-    ```
-    git clone https://github.com/openml/docs.git
-    pip install -r requirements.txt
-    ```
-    To build the documentation, run `mkdocs serve` in the top directory (with the `mkdocs.yml` file). Any changes made after that will be hot-loaded.
+To build the documentation locally, first make sure all dependencies specified in `requirements.txt` are installed:
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+python -m pip install uv
+uv pip install -r requirements.txt
+```
 
-    The documentation will be auto-deployed with every push or merge with the master branch of `https://www.github.com/openml/docs/`. In the background, a CI job
-    will run `mkdocs gh-deploy`, which will build the HTML files and push them to the gh-pages branch of openml/docs. `https://docs.openml.org` is just a reverse proxy for `https://openml.github.io/docs/`.
+After installing the dependencies, run `mkdocs serve -f mkdocs-local.yml` in the top directory (with the `mkdocs.yml` file). Any changes made after that will be hot-loaded.
 
+To build the full documentation, including importing the documentation from other repositories, run `mkdocs serve` in the top directory (with the `mkdocs.yml` file). This can take a while to compile, so only use this when needed. You might also need to set `export NUMPY_EXPERIMENTAL_DTYPE_API=1` (or `set NUMPY_EXPERIMENTAL_DTYPE_API=1` on Windows).
 
 ## Python API
 To edit the tutorial, you have to edit the `reStructuredText` files on [openml-python/doc](https://github.com/openml/openml-python/tree/master/doc). When done, you can do a pull request.

+## :key: Authentication
+
+OpenML is entirely open and you do not need an account to access data (rate limits apply). However, <a href="https://www.openml.org" target='blank_'>signing up via the OpenML website</a> is very easy (and free) and required to upload new resources to OpenML and to manage them online.
+
+API authentication happens via an **API key**, which you can find in your profile after logging in to openml.org. 
+
+```
+openml.config.apikey = "YOUR KEY"
+```
+
+## :joystick: Minimal Example
+
+:material-database: Use the following code to load the [credit-g](https://www.openml.org/search?type=data&sort=runs&status=active&id=31) [dataset](https://docs.openml.org/concepts/data/) directly into a pandas dataframe. Note that OpenML can automatically load all datasets, separate data X and labels y, and give you useful dataset metadata (e.g. feature names and which ones have categorical data).
+
+```python
+import openml
+
+dataset = openml.datasets.get_dataset("credit-g") # or by ID get_dataset(31)
+X, y, categorical_indicator, attribute_names = dataset.get_data(target="class")
+```
+
+
+:trophy: Get a [task](https://docs.openml.org/concepts/tasks/) for [supervised classification on credit-g](https://www.openml.org/search?type=task&id=31&source_data.data_id=31). 
+Tasks specify how a dataset should be used, e.g. including train and test splits.
+
+```python
+task = openml.tasks.get_task(31)
+dataset = task.get_dataset()
+X, y, categorical_indicator, attribute_names = dataset.get_data(target=task.target_name)
+# get splits for the first fold of 10-fold cross-validation
+train_indices, test_indices = task.get_train_test_split_indices(fold=0)
+```
+
+:bar_chart: Use an [OpenML benchmarking suite](https://docs.openml.org/concepts/benchmarking/) to get a curated list of machine-learning tasks:
+```python
+suite = openml.study.get_suite("amlb-classification-all")  # Get a curated list of tasks for classification
+for task_id in suite.tasks:
+    task = openml.tasks.get_task(task_id)
+```
+
+:star2: You can now benchmark your models easily across many datasets at once. A model training is called a run:
+
+```python
+from sklearn import neighbors
+
+task = openml.tasks.get_task(403)
+clf = neighbors.KNeighborsClassifier(n_neighbors=5)
+run = openml.runs.run_model_on_task(clf, task)
+```
+
+:raised_hands: You can now publish your experiment on OpenML so that others can build on it:
+
+```python
+myrun = run.publish()
+print(f"kNN on {data.name}: {myrun.openml_url}")
+```
