 ## BREAKING CHANGES
 
 <!-- * Restructured `src` directory (PR #3). -->
 
 ## NEW FUNCTIONALITY
 
-* Added `control_methods/true_labels` component (PR #5).
-
-* Added `methods/logistic_regression` component (PR #5).
-
-* Added `metrics/accuracy` component (PR #5).
 
 ## MAJOR CHANGES
 
-* Updated `api` files (PR #5).
-
-* Updated configs, components and CI to the latest Viash version (PR #8).
-
-* Updated to Viash 0.9.4 (PR #12).
-
-* Use dependencies in `openproblems-bio/openproblems` (PR #12).
+* Updated `api` files and set the data processor (PR #1).
 
 ## MINOR CHANGES
 
-* Updated `README.md` (PR #5).
-
-* `run_benchmark`: write the commit the workflow ran from and the launch time into
-  `task_info.yaml`, instead of publishing `_viash.yaml` verbatim (PR #18).

+label: Spatial Trajectory Inference
+summary: Predicting the spatial trajectory of cells in a tissue based on spatial transcriptomics data.
+description: 
 
-  Explain the motivation behind your proposed task. Describe the biological or computational 
-  problem you aim to address and why it's important. Discuss the current state of research in
-  this area and any gaps or challenges that your task could help address. This section 
-  should convince readers of the significance and relevance of your task.
+  Spatial transcriptomics preserves each cell's physical position alongside its expression profile, enabling pseudotime prediction using 2D spatial context.
+  Different methods make different assumptions about resolution, input format, and output, and are further complicated by spatial batch effects not present in dissociated single-cell data.
+  While dynbenchmark resolved this comparison problem for non-spatial trajectory inference methods, no equivalent standardized benchmark exists for spatial pseudotime prediction, and existing method papers are validated only against each other or qualitative marker trends rather than tissues with independently known trajectories.
+
+  This task benchmarks pseudotime prediction methods on 2D tissue datasets with well-characterized ground-truth spatial axes.
+  Input data consists of AnnData objects containing 2D spatial transcriptomics data with spatial coordinates.
+  The output is a set of quantitative metric scores comparing each method's predicted pseudotime against ground truth, capturing both trajectory accuracy and preservation of relevant biological information.
