 ## Unreleased
 
 ### Added
+- Added `make_scorecard.sh` and documentation to `inst/ilamb/` in PEcAn.benchmark for generating and serving the ILAMB HTML scorecard.
 - New function `PEcAn.utils::netcdf2df()` flattens all dims and vars of a netCDF into a dataframe,
     with units attached as an attribute.
 - New package `PEcAn.RothC` runs the RothC soil carbon model.

+## Generating the scorecard
+
+ILAMB produces an interactive HTML scorecard alongside the numeric scores. To
+generate it for a window, run `make_scorecard.sh` against that window's model
+root (built by the pipeline above):
+
+```bash
+export ILAMB_ROOT=/path/to/ILAMB_ROOT
+./make_scorecard.sh 2012_2014
+./make_scorecard.sh 2015_2023
+```
+
+Each run writes a self-contained static site (`index.html` plus assets) to a
+build directory, which can be served directly by copying it under a web
+server's document root. The scorecard uses the clean model roots, so it lists
+PEcAn alongside the individual CMIP6 and TRENDY models and the ensemble means,
+rather than the 100 individual PEcAn members used for the spread analysis.

+# Generate the ILAMB HTML scorecard for a PEcAn benchmarking window.
+#
+# Runs ilamb-run against a window's model root (PEcAn, the individual CMIP6
+# and TRENDY models, and the ensemble means) to produce the interactive HTML
+# scorecard ILAMB writes to the build directory. This is the public-facing
+# comparison view; it uses the clean model roots (no individual PEcAn members),
+# so the scorecard lists PEcAn alongside the models rather than 100 member rows.
+#
+# Prerequisites:
+#   - ILAMB installed and on PATH (ilamb-run).
+#   - ILAMB_ROOT set, with the benchmark datasets under $ILAMB_ROOT/DATA.
+#   - The window model root already built (see build_window_ensembles.py),
+#     e.g. ilamb_models_2012_2014 / ilamb_models_2015_2023.
+#
+# Usage:
+#   ./make_scorecard.sh <window> [model_root] [build_dir]
+#
+#   window      Required. A label for the run, e.g. 2012_2014 or 2015_2023.
+#   model_root  Optional. Directory of model entities to score.
+#               Default: ilamb_models_<window>.
+#   build_dir   Optional. Output directory for the HTML scorecard.
+#               Default: ilamb_scorecard_<window>.
+#
+# Example:
+#   export ILAMB_ROOT=/path/to/ILAMB_ROOT
+#   ./make_scorecard.sh 2012_2014
+#   ./make_scorecard.sh 2015_2023
+#
+# The generated build directory (index.html plus assets) is a self-contained
+# static site that can be served directly, for example by copying it under a
+# web server's document root.
