+Inference via CLI
+-----------------
+
+Command Line Interface (CLI)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+You can use the CLI to run inference on an image or folder containing several images. To do that, you can use the following command
+
+.. code-block:: console
+
+   $ spotiflow predict --input PATH
+
+where ``PATH`` can be either an image or a folder. By default, the command will use the ``general`` pretrained model. You can specify a different model by using the ``--pretrained-model`` flag. Moreover, spots are saved to a subfolder ``spotiflow_results`` created inside the input folder (this can be changed with the ``--out-dir`` flag). For more information, please refer to the help message of the CLI (``spotiflow-predict -h``).

+Fine-tuning a Spotiflow model on a custom dataset
+-------------------------------------------------
+
+Data format
+^^^^^^^^^^^
+
+See :ref:`train:Data format`.
+
+Fine-tuning (CLI)
+^^^^^^^^^^^^^^^^^
+
+You can fine-tune from an existing model by simply adding an argument to the CLI call. See :ref:`train:Basic training (CLI)` for more information.
+
+.. code-block:: console
+
+    spotiflow-train /path/to/spots_data --save-dir /my/trained/model --pretrained-model general
+
+where `/path/to/pretrained/model` is the path to the directory containing the model you want to fine-tune. You can also pass other parameters to the training, such as the number of epochs, the learning rate, etc. For more information on the arguments allowed, see the documentation of the CLI command:
+
+
+Fine-tuning (API)
+^^^^^^^^^^^^^^^^^
+
+Finetuning a pre-trained model on a custom dataset is very easy. You can load the model very similarly to what you would normally do to predict on new images (you only need to add one extra parameter!):
+
+.. code-block:: python
+
+    from spotiflow.model import Spotiflow
+    from spotiflow.utils import get_data
+
+    # Get the data
+    train_imgs, train_spots, val_imgs, val_spots = get_data("/path/to/spots_data")
+
+    # Initialize the model
+    model = Spotiflow.from_pretrained(
+        "general",
+        inference_mode=False,
+    )
+
+    # Train and save the model
+    model.fit(
+        train_imgs,
+        train_spots,
+        val_imgs,
+        val_spots,
+        save_dir="/my/trained/model",
+    )
+
+Of course, you can also fine-tune from a model you have trained before. In that case, use the ``from_folder()`` method instead of ``from_pretrained()`` (see :ref:`index:Predicting spots in an image`).
+All the information about training customization from :ref:`train:Customizing the training` applies here as well. However, note that you cannot change the model architecture when fine-tuning!

+:hero: Spotiflow: accurate and robust spot detection for fluorescence microscopy 
+
+=========
+Spotiflow
+=========
+
+Spotiflow is a learning-based subpixel-accurate spot detection method for 2D and 3D fluorescence microscopy. It is primarily developed for spatial transcriptomics workflows that require transcript detection in large, multiplexed FISH-images, although it can also be used to detect spot-like structures in general fluorescence microscopy images and volumes. For more information, please refer to our `paper <https://doi.org/10.1101/2024.02.01.578426/>`__. 
+
+Getting Started
+---------------
+
+Installation
+~~~~~~~~~~~~
+
+
+First, create and activate a fresh ``conda`` environment (we currently support Python 3.9 to 3.12). If you don't have ``conda`` installed, we recommend using `miniforge <https://github.com/conda-forge/miniforge>`__.
+
+.. code-block:: console
+
+   $ conda create -n spotiflow python=3.12
+   $ conda activate spotiflow
+
+**Note (for MacOS users):** if using MacOS, there is a known bug causing the installation of PyTorch with conda to sometimes break OpenMP. You can avoid installing PyTorch with ``conda`` and let install it automatically via pip instead.
+Then, install Pytorch using ``conda``/ ``mamba``. Please follow the `official instructions for your system <https://pytorch.org/get-started/locally>`__.
+
+As an example, for a Linux system with CUDA (note that you should change the CUDA version to match the one installed on your system):
+
+.. code-block:: console
+
+   $ conda install pytorch torchvision pytorch-cuda=12.1 -c pytorch -c nvidia
+
+**Note (for Windows users):** if using Windows, if using Windows, please install the latest `Build Tools for Visual Studio <https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2022>`__ (make sure to select the C++ build tools during installation) before proceeding to install Spotiflow.
+
+Finally, install ``spotiflow`` using ``pip``:
+
+.. code-block:: console
+
+   $ pip install spotiflow
+
+Predicting spots in an image
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Python API
+^^^^^^^^^^
+
+The snippet below shows how to retrieve the spots from an image using one of the pretrained models:
+
+.. code-block:: python
+
+   from skimage.io import imread
+   from spotiflow.model import Spotiflow
+   from spotiflow.utils import write_coords_csv
+   
+
+   # Load the desired image
+   img = imread("/path/to/your/image") 
+ 
+   # Load a pretrained model
+   model = Spotiflow.from_pretrained("general")
+
+   # Predict spots
+   spots, details = model.predict(img) # predict expects a numpy array
+
+   # spots is a numpy array with shape (n_spots, 2)
+   # details contains additional information about the prediction, like the predicted heatmap, the probability per spot, the flow field, etc.
+
+   # Save the results to a CSV file
+   write_coords_csv(spots, "/path/to/save/spots.csv")
+
+If a custom model is used, simply change the model loadings step to:
+
+.. code-block:: python
+
+   # Load a custom model
+   model = Spotiflow.from_folder("/path/to/model")
+
+Command Line Interface (CLI)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+You can use the CLI to run inference on an image or folder containing several images. To do that, you can use the following command
+
+.. code-block:: console
+
+   $ spotiflow predict --input PATH
+
+where ``PATH`` can be either an image or a folder. By default, the command will use the ``general`` pretrained model. You can specify a different model by using the ``--pretrained-model`` flag. Moreover, spots are saved to a subfolder ``spotiflow_results`` created inside the input folder (this can be changed with the ``--out-dir`` flag). For more information, please refer to the help message of the CLI (``spotiflow-predict -h``).
+
+Napari plugin
+^^^^^^^^^^^^^
+Spotiflow also can be run easily in a graphical user interface as a `napari <https://napari.org/>`__ plugin. See :ref:`napari:Predicting spots using the napari plugin` for more information.

+Predicting spots using the napari plugin
+----------------------------------------
+
+The napari plugin can be used to predict spots in a napari viewer. First, you must install it in the environment containing Spotiflow:
+
+.. code-block:: console
+
+    (spotiflow) $ pip install napari-spotiflow
+
+The plugin will then be available in the napari GUI under the name "Spotiflow widget". This is how the GUI looks like:
+
+.. image:: ./_static/spotiflow_napari_gui.png
+    :width: 700
+    :align: center
+
+The plugin allows running on two modes: for images (``2D``) and volumes (``3D``), which can be toggled using the corresponding  buttons in the GUI. You can also run on movies by setting the appropriate axis order (should be leading with a `T`).
+
+Upon pressing the button ``Run``, The plugin will create a ``Points`` layer containing the predicted spots:
+
+.. image:: ./_static/spotiflow_napari_preds.png
+    :width: 700
+    :align: center
+
+If the option ``Show CNN output`` is checked, the plugin will also create two ``Image`` layers containing the heatmap output of the CNN as well as the stereographic flow.
+
+Finally, the plugin includes two sample 2D images (HybISS and Terra) as well as a synthetic 3D volume. These samples can be loaded from the ``File`` menu (``File -> Open sample -> napari-spotiflow``). You can try the plugin with these samples to get a better idea of how it works!

+Available pre-trained models
+----------------------------
+
+The following pre-trained models are available (for a more detailed description, please refer to the *Methods* section of the paper as well as *Supplementary Table 2*):
+
+- ``general``: trained on a diverse dataset of spots of different modalities acquired in different microscopes with different settings. This model is the default one used in the CLI (pixel sizes: 0.04µm, 0.1µm, 0.11µm, 0.15µm, 0.32µm, 0.34µm).
+- ``hybiss``: trained on HybISS data acquired in 3 different microscopes (pixel sizes: 0.15µm, 0.32µm, 0.34µm).
+- ``synth_complex``: trained on synthetic data, which includes simulations of aberrated spots and fluorescence background (pixel size: 0.1µm).
+- ``synth_3d``: trained on synthetic 3D data, which includes simulations of aberrated spots and Z-related artifacts (voxel size: 0.2µm).
+- ``smfish_3d``: fine-tuned from the ``synth_3d`` model on smFISH 3D data of *Platynereis dumerilii* (voxel size: 0.13µm (YX), 0.48µm (Z)).
+
+You can use these models to predict spots in images or to fine-tune them on a few annotations of your own data. The models can be loaded via the API as follows:
+
+.. code-block:: python
+
+    from spotiflow.model import Spotiflow
+
+    pretrained_model_name = "general"
+    model = Spotiflow.from_pretrained(pretrained_model_name)
+
+You can also load them from the napari plugin or from the CLI by specifying the name of the model. See :ref:`napari:Predicting spots using the napari plugin` and :ref:`cli:Inference via CLI` for more information respectively.
