-## Usage
-### Logging
-Training log extraction with LogIX is as simple as adding one `with` statement to the existing
-training code. LogIX automatically extracts user-specified logs using PyTorch hooks, and stores
-it as a tuple of `([data_ids], log[module_name][log_type])`. If needed, LogIX writes these logs
-to disk efficiently with memory-mapped files.
-
-```python
-import logix
+## Easy to Integrate
 
-# Initialze LogIX
-run = logix.init(project="my_project")
-
-# Specify modules to be tracked for logging
-run.watch(model, name_filter=["mlp"], type_filter=[nn.Linear])
-
-# Specify plugins to be used in logging
-run.setup({"grad": ["log", "covariance"]})
-run.save(True)
-
-for batch in data_loader:
-    # Set `data_id` (and optionally `mask`) for the current batch 
-    with run(data_id=batch["input_ids"], mask=batch["attention_mask"]):
-        model.zero_grad()
-        loss = model(batch)
-        loss.backward()
-# Synchronize statistics (e.g. covariance) and write logs to disk
-run.finalize()
-```
-
-### Training Data Attribution
-As a part of our initial research, we implemented influence functions using LogIX. We plan to provide more
-pre-implemented interpretability algorithms if there is a demand.
-
-```python
-# Build PyTorch DataLoader from saved log data
-log_loader = run.build_log_dataloader()
-
-with run(data_id=test_batch["input_ids"]):
-    test_loss = model(test_batch)
-    test_loss.backward()
-
-test_log = run.get_log()
-run.influence.compute_influence_all(test_log, log_loader) # Data attribution
-run.influence.compute_self_influence(test_log) # Uncertainty estimation

+Our software design allows for the seamless integration with popular high-level frameworks including

+[PyTorch Lightning](https://github.com/Lightning-AI/pytorch-lightning), that conveniently handles
