+panel
+=====
+
+This is mainly the interface of [repoapi](../repoapi/models/jbi.py). There are some panels
+for releases and projects.
+
+Panels use [boostrap v3.3.7](panel/static/panel/js/bootstrap.min.js) toolkit and
+[django-assets](https://django-assets.readthedocs.io/en/latest/staticfiles.html)
+
+There's some javascript logic at [panel*.js](panel/static/panel/js/panel_release.js).
+It will make things dynamic so build results will appear with refresh the whole page
+and some other tricks.
