This website is created by Helmholtz HZI to support the open collaboration of researchers around COVID-19.

Get help

For any issues with the site including typos or rendering issues, please file an issue or send a pull request. The site automatically deploys once pull requests are merged.

Contributing content

To contribute content, you can create a Pull Request with the content.

  1. Fork the repository (repo) of the serohub website.
  2. Draft your post in R Markdown or Markdown.
  3. (Optional) Preview and refine your post locally.
  4. Submit via pull request and preview your post.
  5. A SeroHub maintainer accepts your content, or requests changes.

An excellent place to learn about contributing science related blog posts is ropensci technical guidelines.

Add a researcher

If you would like to add a researcher, the general content steps are taken but instead of generating files with markdown you amend the Researcher list.

Making changes to the website

For changes to the website, there are a few key areas:

  • The config file that supports changing many values used in the repository
  • index.html determines what the home page looks like. It may reference files in syntax like {{ partial "leaflet.html" . }} -- these are sub-templates and are found in layouts/partials
  • baseof.html describes header and footer content used across the site. This is where you would change things like JavaScript files, the nav bar, and the footer
  • contains the html used to generate the contact form that will submit the contents to netlify. Note the Netlify free tier has an upload limit of 10Mb per month. This is not a long-term solution.
  • hzi.css is the custom style sheet for the website. Use this to tweak or override the website appearance.


The default site (en):

  • The folder content/publication contains the reference to scientific papers. It's our main folder to curate publications!
  • Each .md refers to one scientific paper, and is named by its DOI, e.g.
  • The markdown files are organized by the publisher, e.g. content/publication/biorxiv/

The language-specific sites (e.g. de):

  • The majority of scientific papers are written in English language.
  • In config.toml each language (except en) has an additional content folder defined, e.g. contentDir="content_de" for the German site.
  • In order to display English papers, we will copy/mirror whole folders to the language-specific directory, e.g. cp content/publication/biorxiv content_de/publication/biorxiv

Getting things set up locally

Get the repo locally

  1. If you're a member of the organisation, git clone --recurse-submodules
  2. If you're not a member of the organisation, fork the repo, then
    • git clone --recurse-submodules<your account>/serohub.git
    • git remote add upstream

Get the submodule

We use a theme hugo-infinite as the basis for the site. The --recurse-submodules argument in git clone will have established a connection. You should not make changes to contents in the submodule instead, you should copy files from the themes structure and paste them into the corresponding section of the main repository and edit it there. You only work with the submodule contents directly if you want to fix a bug and that is best done with a fresh fork of the theme directly from the theme's repository.

Run hugo locally

From inside the website directory, run hugo serve to get a live local copy (typically on http://localhost:1313) that will update whenever you make changes.



We will host the solution on Netlify with the source files hosted on GitHub. This will enable HZI researchers to work in an open way and accept collaborations from others.


This website uses Hugo. To work with Hugo locally, you will need to install it.

Hugo is a website generator that pre-generates web pages so that they can be hosted very cheaply. It is used by a significant amount of the research and science communities due to its excellent support for markdown which enables researchers to use literate programming techniques in R and Python to interleave analysis and text.


The website is hosted on Netlify.

Automated deployments

The website is automatically updated everytime there is a change to the master branch in GitHub. Additionally, any pull requests or branches will also have preview URLs built. The preview links for Pull Requests will be included in the Pull Request interface on GitHub.


The Netlify hosting has Visitor access > OAuth authentication enabled with a GitHub OAuth application - this is important for the Netlify CMS to support open authoring.


Netlify can support custom SSL certificates to be associated with the intended domain of The SSL can either be a letsencrypt managed certificate or it can support a wildcard domain SSL. Note that the custom certificate route requires the SSL certificate to be updated manually, whenever a new one is issued.

Netlify CMS

The user interface for adding and managing studies is built using the Netlify CMS.

How it works

The CMS is used to provide an interface to GitHub and Git activities behind the scenes. You can login with your Github account at Please note,

  • You need to use a github account that has NO access rights to the serohub repository. When you write a blog post ("General Content"), a study, or publication, it will create a fork of the repository in the users account and they can perform edits that will become pull requests for serohub maintainers to approve.
  • If you are a maintainer or have any write access rights to serohub repository, you will end with an error Failed to persist entry: API_ERROR: Not Found when trying to save a new blog entry.



The LEOSS.sero-survey platform is a crucial and independent infrastructure to accelerate research about the seroprevalence of SARS-CoV-2.
