 # ClusterLabs.org website
 
 ## Dependencies
 
 ClusterLabs.org is primarily generated by Hugo, a static website generator.
-The site's only dependencies are Go >= 1.18.0 and Hugo >= 0.128.0.
+The site's only dependencies are Go >= 1.18.0 and Hugo >= 0.128.0. (Hugo
+0.136.0 and 0.136.5 are specifically known to work.)
 
 If your OS does not provide Hugo, you can download an architecture-specific
 tarball from https://github.com/gohugoio/hugo/releases/latest, extract it,
 and move the binary to somewhere on your $PATH.
 
 ## Building the site
 
 The hugo command must be run from the `src` directory.
 
 To generate a live preview in a checkout, run `hugo server`. To generate final
 content on disk (whether in a checkout or on the production site), run `hugo`.
 
 Hugo will put the generated files in the `html` directory (which is excluded
 from version control). Existing files there will be overwritten but not
 deleted, so anything removed from the source has to be removed from a
 previously generated `html` directory manually. For testing a checkout, it's
 fine to simply erase `html` entirely before regenerating, but on the live
 server, there are non-version-controlled files that must be kept (including
 `html/images` and much of `html/projects/pacemaker`).
 
 If you want to test the PHP pages in the site, `hugo server` will not be
 sufficient. You'll have to install a PHP-enabled local webserver (such as
 Apache or Nginx) and use your checkout's `html` directory as the document root.
 
 ## Using Hugo
 
 ClusterLabs uses Hugo's Congo theme, as a Go module. When you create a
 checkout, run `hugo mod get` once. To update the site to the latest version of
 the theme, run `hugo mod get -u`.
 
 Hugo does not follow symbolic links.
 
 Configuration files and front matter are in TOML format.
 
 The source is in Goldmark (CommonMark and GitHub Flavored Markdown with
 extensions).
 
 ## Source directory layout
 
 * `archetypes/default.md`: This initializes the front matter of pages created
   with the `hugo new content` command.
 
 * `config/_default/`: Configuration for Hugo and Congo.
 
 * `content/`: Page source lives beneath here (as `.md` files). URL paths will
   mirror this directory hierarchy. The home page is `content/_index.md`; each
   other page should have its own subdirectory.
 
   If a page directory has subdirectories, the page source should be `_index.md`
   and will get an automatic listing of all subpages unless `layout = "single"`
   is added to its front matter. With no subdirectories, the name should be
   `index.md`.
 
   If a page directory contains an image whose name starts with `cover`, it will
   be used as a splash image and should be 1320 pixels wide. You can also
   provide a 160-pixel-wide by 120-pixel-high thumbnail named starting with
   `thumb` which will be used in automatically generated page listings.
 
 * `layouts/`: Page templates. `layouts/_defaults/` contains layouts for PHP
   pages (copied from the theme's layouts for HTML pages). `layouts/partials/`
   contains snippets that can be included by pages or other layouts (these also
   were copied from the theme, then customized).
 
 * `resources/`: Automatically maintained cache
 
 * `static/`: Files that will be copied as-is rather than generated (images,
   CSS, etc.) and can be used on any page. Like `content/`, the URL paths will
   mirror the directory hierarchy.
 
 ## Web server configuration
 
 The clusterlabs.org web server is configured to redirect certain old URLs to
 their new locations, so be careful about renaming files. A helpful feature is
 the ability to put `aliases = ["/some/url/path", ...]` in a page's front matter
 with URL paths that will be redirected to the page's main URL.

 You have followed a link to documentation for Pacemaker versions that are no
 longer supported. Most likely, you want the
 [current documentation](/projects/pacemaker/doc/). Otherwise, you can find
