+    Creates a new Trackio project and returns a [`Run`] object.
+
+    Args:
+        project (`str`):
+            The name of the project (can be an existing project to continue tracking or
+            a new project to start tracking from scratch).
+        name (`str`, *optional*):
+            The name of the run (if not provided, a default name will be generated).
+        group (`str`, *optional*):
+            The name of the group which this run belongs to in order to help organize
+            related runs together. You can toggle the entire group's visibilitiy in the
+            dashboard.
+        space_id (`str`, *optional*):
+            If provided, the project will be logged to a Hugging Face Space instead of
+            a local directory. Should be a complete Space name like
+            `"username/reponame"` or `"orgname/reponame"`, or just `"reponame"` in which
+            case the Space will be created in the currently-logged-in Hugging Face
+            user's namespace. If the Space does not exist, it will be created. If the
+            Space already exists, the project will be logged to it.
+        space_storage ([`~huggingface_hub.SpaceStorage`], *optional*):
+            Choice of persistent storage tier.
+        dataset_id (`str`, *optional*):
+            If a `space_id` is provided, a persistent Hugging Face Dataset will be
+            created and the metrics will be synced to it every 5 minutes. Specify a
+            Dataset with name like `"username/datasetname"` or `"orgname/datasetname"`,
+            or `"datasetname"` (uses currently-logged-in Hugging Face user's namespace),
+            or `None` (uses the same name as the Space but with the `"_dataset"`
+            suffix). If the Dataset does not exist, it will be created. If the Dataset
+            already exists, the project will be appended to it.
+        config (`dict`, *optional*):

+            `wandb.init()`.
+        resume (`str`, *optional*, defaults to `"never"`):
+            Controls how to handle resuming a run. Can be one of:
+
+            - `"must"`: Must resume the run with the given name, raises error if run
+              doesn't exist
+            - `"allow"`: Resume the run if it exists, otherwise create a new run
+            - `"never"`: Never resume a run, always create a new one
+        private (`bool`, *optional*):
+            Whether to make the Space private. If None (default), the repo will be
+            public unless the organization's default is private. This value is ignored
+            if the repo already exists.
+        settings (`Any`, *optional*):
+            Not used. Provided for compatibility with `wandb.init()`.
+        embed (`bool`, *optional*, defaults to `True`):
+            If running inside a Jupyter/Colab notebook, whether the dashboard should
+            automatically be embedded in the cell when trackio.init() is called. For
+            local runs, this launches a local Gradio app and embeds it. For Space runs,
+            this embeds the Space URL. In Colab, the local dashboard will be accessible
+            via a public share URL (default Gradio behavior).
+        auto_log_gpu (`bool` or `None`, *optional*, defaults to `None`):
+            Controls automatic GPU metrics logging. If `None` (default), GPU logging
+            is automatically enabled when `nvidia-ml-py` is installed and an NVIDIA
+            GPU is detected. Set to `True` to force enable or `False` to disable.
+        gpu_log_interval (`float`, *optional*, defaults to `10.0`):
+            The interval in seconds between automatic GPU metric logs.
+            Only used when `auto_log_gpu=True`.
+        webhook_url (`str`, *optional*):
+            A webhook URL to POST alert payloads to when `trackio.alert()` is
+            called. Supports Slack and Discord webhook URLs natively (payloads
+            are formatted automatically). Can also be set via the
+            `TRACKIO_WEBHOOK_URL` environment variable. Individual alerts can
+            override this URL by passing `webhook_url` to `trackio.alert()`.
+        webhook_min_level (`AlertLevel` or `str`, *optional*):
+            Minimum alert level that should trigger webhook delivery.
+            For example, `AlertLevel.WARN` sends only `WARN` and `ERROR`
+            alerts to the webhook destination. Can also be set via
+            `TRACKIO_WEBHOOK_MIN_LEVEL`.
+    Returns:
+        `Run`: A [`Run`] object that can be used to log metrics and finish the run.

+            Whether to show the Gradio footer. When `False`, the footer will be hidden.
+            This can also be controlled via the `footer` query parameter in the URL.
+        color_palette (`list[str]`, *optional*):
+            A list of hex color codes to use for plot lines. If not provided, the
+            `TRACKIO_COLOR_PALETTE` environment variable will be used (comma-separated
+            hex codes), or if that is not set, the default color palette will be used.
+            Example: `['#FF0000', '#00FF00', '#0000FF']`
+        open_browser (`bool`, *optional*, defaults to `True`):
+            If `True` and not in a notebook, a new browser tab will be opened with the
+            dashboard. If `False`, the browser will not be opened.
+        block_thread (`bool`, *optional*):
+            If `True`, the main thread will be blocked until the dashboard is closed.
+            If `None` (default behavior), then the main thread will not be blocked if the
+            dashboard is launched in a notebook, otherwise the main thread will be blocked.
+        host (`str`, *optional*):
+            The host to bind the server to. If not provided, defaults to `'127.0.0.1'`
+            (localhost only). Set to `'0.0.0.0'` to allow remote access.
+
+        Returns:
+            `app`: The Gradio app object corresponding to the dashboard launched by Trackio.
+            `url`: The local URL of the dashboard.
+            `share_url`: The public share URL of the dashboard.
+            `full_url`: The full URL of the dashboard including the write token (will use the public share URL if launched publicly, otherwise the local URL).

+    Scheduler to upload a local folder to the Hub at regular intervals (e.g. push to hub every 5 minutes).
+
+    The recommended way to use the scheduler is to use it as a context manager. This ensures that the scheduler is
+    properly stopped and the last commit is triggered when the script ends. The scheduler can also be stopped manually
+    with the `stop` method. Checkout the [upload guide](https://huggingface.co/docs/huggingface_hub/guides/upload#scheduled-uploads)
+    to learn more about how to use it.
+
+    Args:
+        repo_id (`str`):
+            The id of the repo to commit to.
+        folder_path (`str` or `Path`):
+            Path to the local folder to upload regularly.
+        every (`int` or `float`, *optional*):
+            The number of minutes between each commit. Defaults to 5 minutes.
+        path_in_repo (`str`, *optional*):
+            Relative path of the directory in the repo, for example: `"checkpoints/"`. Defaults to the root folder
+            of the repository.
+        repo_type (`str`, *optional*):
+            The type of the repo to commit to. Defaults to `model`.
+        revision (`str`, *optional*):
+            The revision of the repo to commit to. Defaults to `main`.
+        private (`bool`, *optional*):
+            Whether to make the repo private. If `None` (default), the repo will be public unless the organization's default is private. This value is ignored if the repo already exists.
+        token (`str`, *optional*):
+            The token to use to commit to the repo. Defaults to the token saved on the machine.
+        allow_patterns (`List[str]` or `str`, *optional*):
+            If provided, only files matching at least one pattern are uploaded.
+        ignore_patterns (`List[str]` or `str`, *optional*):
+            If provided, files matching any of the patterns are not uploaded.
+        squash_history (`bool`, *optional*):
+            Whether to squash the history of the repo after each commit. Defaults to `False`. Squashing commits is
+            useful to avoid degraded performances on the repo when it grows too large.
+        hf_api (`HfApi`, *optional*):
+            The [`HfApi`] client to use to commit to the Hub. Can be set with custom settings (user agent, token,...).
+        on_before_commit (`Callable[[], None]`, *optional*):
+            If specified, a function that will be called before the CommitScheduler lists files to create a commit.
+
+    Example:
+    ```py
+    >>> from pathlib import Path
+    >>> from huggingface_hub import CommitScheduler
+
+    # Scheduler uploads every 10 minutes
+    >>> csv_path = Path("watched_folder/data.csv")
+    >>> CommitScheduler(repo_id="test_scheduler", repo_type="dataset", folder_path=csv_path.parent, every=10)
+
+    >>> with csv_path.open("a") as f:
+    ...     f.write("first line")
+
+    # Some time later (...)
+    >>> with csv_path.open("a") as f:
+    ...     f.write("second line")
+    ```
+
+    Example using a context manager:
+    ```py
+    >>> from pathlib import Path
+    >>> from huggingface_hub import CommitScheduler
+
+    >>> with CommitScheduler(repo_id="test_scheduler", repo_type="dataset", folder_path="watched_folder", every=10) as scheduler:
+    ...     csv_path = Path("watched_folder/data.csv")
+    ...     with csv_path.open("a") as f:
+    ...         f.write("first line")
+    ...     (...)
+    ...     with csv_path.open("a") as f:
