 ## Usage
 
-The first step to using the Nucleus library is instantiating a client object.
-The client abstractions serves to authenticate the user and act as the gateway
-for users to interact with their datasets, models, and model runs.
-
-### Create a client object
-
-```python
-import nucleus
-client = nucleus.NucleusClient("YOUR_API_KEY_HERE")
-```
-
-### Create Dataset
-
-```python
-dataset = client.create_dataset("My Dataset")
-```
-
-### List Datasets
-
-```python
-datasets = client.list_datasets()
-```
-### List Jobs
-```python
-jobs = client.list_jobs()
-```
-### Delete a Dataset
-
-By specifying target dataset id.
-A response code of 200 indicates successful deletion.
-
-```python
-client.delete_dataset("YOUR_DATASET_ID")
-```
-
-### Append Items to a Dataset
-
-You can append both local images and images from the web. Simply specify the location and Nucleus will automatically infer if it's remote or a local file.
-
-```python
-dataset_item_1 = DatasetItem(image_location="./1.jpeg", reference_id="1", metadata={"key": "value"})
-dataset_item_2 = DatasetItem(image_location="s3://srikanth-nucleus/9-1.jpg", reference_id="2", metadata={"key": "value"})
-```
-
-The append function expects a list of `DatasetItem` objects to upload, like this:
-
-```python
-response = dataset.append([dataset_item_1, dataset_item_2])
-```
-
-### Get Dataset Info
-
-Tells us the dataset name, number of dataset items, model_runs, and slice_ids.
-
-```python
-dataset.info
-```
-
-### Access Dataset Items
-
-There are three methods to access individual Dataset Items:
-
-(1) Dataset Items are accessible by reference id
-
-```python
-item = dataset.refloc("my_img_001.png")
-```
-
-(2) Dataset Items are accessible by index
-
-```python
-item = dataset.iloc(0)
-```
-
-(3) Dataset Items are accessible by the dataset_item_id assigned internally
-
-```python
-item = dataset.loc("dataset_item_id")
-```
-
-### Add Annotations
-
-Upload groundtruth annotations for the items in your dataset.
-Box2DAnnotation has same format as https://dashboard.scale.com/nucleus/docs/api#add-ground-truth
-
-```python
-annotation_1 = nucleus.BoxAnnotation(reference_id="1", label="label", x=0, y=0, width=10, height=10, annotation_id="ann_1", metadata={})
-annotation_2 = nucleus.BoxAnnotation(reference_id="2", label="label", x=0, y=0, width=10, height=10, annotation_id="ann_2", metadata={})
-response = dataset.annotate([annotation_1, annotation_2])
-```
-
-For particularly large payloads, please reference the accompanying scripts in **references**
-
-### Add Model
-
-The model abstraction is intended to represent a unique architecture.
-Models are independent of any dataset.
-
-```python
-model = client.add_model(name="My Model", reference_id="newest-cnn-its-new", metadata={"timestamp": "121012401"})
-```
-
-### Upload Predictions to ModelRun
-
-This method populates the model_run object with predictions. `ModelRun` objects need to reference a `Dataset` that has been created.
-Returns the associated model_id, human-readable name of the run, status, and user specified metadata.
-Takes a list of Box2DPredictions within the payload, where Box2DPrediction
-is formulated as in https://dashboard.scale.com/nucleus/docs/api#upload-model-outputs
-
-```python
-prediction_1 = nucleus.BoxPrediction(reference_id="1", label="label", x=0, y=0, width=10, height=10, annotation_id="pred_1", confidence=0.9)
-prediction_2 = nucleus.BoxPrediction(reference_id="2", label="label", x=0, y=0, width=10, height=10, annotation_id="pred_2", confidence=0.2)
-
-model_run = model.create_run(name="My Model Run", metadata={"timestamp": "121012401"}, dataset=dataset, predictions=[prediction_1, prediction_2])
-```
-
-### Commit ModelRun
-
-The commit action indicates that the user is finished uploading predictions associated
-with this model run. Committing a model run kicks off Nucleus internal processes
-to calculate performance metrics like IoU. After being committed, a ModelRun object becomes immutable.
-
-```python
-model_run.commit()
-```
-
-### Get ModelRun Info
-
-Returns the associated model_id, human-readable name of the run, status, and user specified metadata.
-
-```python
-model_run.info
-```
-
-### Accessing ModelRun Predictions
-
-You can access the modelRun predictions for an individual dataset_item through three methods:
-
-(1) user specified reference_id
-
-```python
-model_run.refloc("my_img_001.png")
-```
-
-(2) Index
-
-```python
-model_run.iloc(0)
-```
-
-(3) Internally maintained dataset_item_id
-
-```python
-model_run.loc("dataset_item_id")
-```
-
-### Delete ModelRun
-
-Delete a model run using the target model_run_id.
-
-A response code of 200 indicates successful deletion.
-
-```python
-client.delete_model_run("model_run_id")
-```
