+
+This repo provides a Hugo partial and shortcode that generates a graphic that shows off your stack!
+Configuration happens in a simple yaml file (check `./exampleSite/data/stack.yaml`) for an example.
+
+## Quick Start
+
+First add this module to your hugo.toml
+
+```toml
+# edit hugo.toml
+[module]
+[[module.imports]]
+path = 'github.com/aselimov/hugo-stack'
+# or for the guaranteed Shai-Hulud free version
+path = 'forge.alexselimov.com/aselimov/hugo-unified-git-activity'
+```
+
+Then run `hugo mod get -u` to pull the latest version. 
+You should now be able to add the heatmap to your site using either a shortcode in the markdown, e.g.
+
+```
+{{< stack >}}
+```
+
+or as a partial to your html templates:
+
+```
+{{ partial "stack.html" . }}
+```
+
+## Configuration
+
+This plugin contains a single configuration variable that controls the color of the spine/rule next to the text descriptions.
+To configure add the following to your hugo.toml and configure `accentColor` as desired.
+
+```toml
+[params]
+accentColor = "#EF9F27"
+```
