 ### Added
 
+- skipper-clipper-compare 1.0.0 (`images/skipper-clipper-compare/1.0.0`): the
+  pinned Python/bedtools environment for skipper-clipper-snakemake's
+  Skipper-vs-CLIPper comparison, published as
+  `ghcr.io/yeolab/skipper-clipper-compare:1.0.0`.
 - Singularity-first DRUID deployment and tutorial instructions for Dockerless
   clusters, including the tested `sha-7941ba6aebf0fd4beb48643ec373374b50b02bbc`
   image pull command.

+# skipper-clipper-compare 1.0.0
+
+Python environment for `workflow/scripts/compare_skipper_clipper.py` in
+[skipper-clipper-snakemake](https://github.com/byee4/skipper-clipper-snakemake),
+which compares Skipper enriched windows with CLIPper peaks. The image holds the
+environment only; the workflow supplies the script.
+
+Pinned in `environment.yml`: Python 3.12, bedtools 2.31.1, pybedtools 0.12.0,
+pandas 2.2.3, numpy 2.2.6, scipy 1.15.2, matplotlib 3.10.3, seaborn 0.13.2, and
+matplotlib-venn 1.1.2. Everything is on `PATH` without activation, so the image
+works under Singularity/Apptainer:
+
+```bash
+apptainer exec docker://ghcr.io/yeolab/skipper-clipper-compare:1.0.0 \
+    python compare_skipper_clipper.py --help
+```
