 # Website for iDemo Project Decysif
+
+## General
+
+- Site is built with the [Hugo static website
+  generator](https://gohugo.io/documentation/)
+- The base Hugo Theme we use is
+  [gohugo-theme-ananke](https://github.com/theNewDynamic/gohugo-theme-ananke/tree/91df000ca82769a7578df81fa142d1a18e446bc0)
+- The site is deployed again with every merge onto `main`, or manually through
+  the github Actions tab in the repository. As of today, a staging website is
+  built only on your fork of the website **if you activate a Github Action for
+  it**. We have not yet changed the CI triggers to look at merge-requests
+  towards `main`.
+
+## Local run method
+
+- [Install Hugo](https://gohugo.io/installation/).
+- Have latest version of the website available locally.
+- From the root of the project, use the following:
+```shell-session
+$ rm -rf public resources && HUGO_ENV="production" hugo --gc --minify server --noHTTPCache --logLevel info
+[...]
+Built in 98 ms
+Environment: "production"
+Serving pages from disk
+Running in Fast Render Mode. For full rebuilds on change: hugo server --disableFastRender
+Web Server is available at http://localhost:1313/ (bind address 127.0.0.1) 
+Press Ctrl+C to stop

+- `assets`: all scripts, CSS and JS to be processed and loaded;
+- `content`: all website's content dataset. Files are `.md` but we only really
+  use Hugo's [`Front
+  Matter`](https://gohugo.io/content-management/front-matter/) feature. This
+  allows us to reference the content through the variables defined in the
+  `Front Matter` and keep templates nice and tidy;
+- `layouts`: the website's functional center. This directory holds all
+  [`templates`](https://gohugo.io/templates/) used to generate the website. I
+  recommended looking into Hugo's [Lookup
+  Order](https://gohugo.io/templates/lookup-order/) to understand the logic
+  behind it but you can have an intuition of it when looking at the
+  similarities between the `content` and the `layouts` directories;
+- `layouts/shortcodes`: read up on shortcodes
+  [here](https://gohugo.io/content-management/shortcodes/#what-a-shortcode-is);
+- `layouts/partials`: read up on partials
+  [here](https://gohugo.io/templates/partial/);
+- `static/**`: static files like downloadable content and images;
+- `theme`: a git submodule pointing to the `ananke` theme;
