This guide explains how to correctly add a post-mortem report for your SICSS location to the website.
Post-mortems are reflective reports that describe:
- How the Institute was run
- What worked well
- What could be done differently next time
These reports help future organizers learn from past experiences and improve their own SICSS locations.
To add a post-mortem for your location, you need to create or update three files:
Location: _data/{year}/{location}/sidebar.yml
Add a post-mortem entry to your location's sidebar navigation. This creates a link in your location's sidebar menu.
Example: For SICSS-Saarbrücken 2025 (_data/2025/saarbrucken/sidebar.yml):
- name: "Post Mortem"
url: "post-mortem"
link: '#saarbrucken'Important: The link value must match the anchor ID you'll use in the year's post-mortem.md file (see step 3).
Location: _data/{year}/{location}/post_mortem.yml
Create a simple YAML file with a title entry. This signals to the website that a post-mortem exists for this location.
Example: For SICSS-Saarbrücken 2025 (_data/2025/saarbrucken/post_mortem.yml):
- title: "Post-Mortem"
- text: |
Your organizing team consisted of...
[Post-mortem content can go here, or in the year's post-mortem.md file]Note: You can include the full post-mortem text in this file using the text field with the pipe (|) character for multi-line content, OR you can put the content in the year's post-mortem.md file (recommended for longer reports).
Location: {year}/post-mortem.md
This is the main post-mortem page that displays all location reports for a given year. If this file doesn't exist yet, create it.
Example: For 2025 (2025/post-mortem.md):
---
title: "Post-Mortems"
subtitle: "A collection of post-mortems"
layout: about
---
<h2 class="display-4">Summer Institutes in Computational Social Science 2025 Post-mortem</h2>
**Published on:** [Date]
[Introduction paragraph about the year's SICSS program]
These post-mortems describe, for each site, a) how the Institute was run, b) what each site thinks worked well, and c) what each site will do differently next time.
Skip to:
- [SICSS-Location1](#location1)
- [SICSS-Location2](#location2)
<h2 class="display-4" id="location1">SICSS-Location1</h2>
[Post-mortem content for Location 1]
<h2 class="display-4" id="location2">SICSS-Location2</h2>
[Post-mortem content for Location 2]Critical Requirements:
- Use the
layout: aboutin the front matter - Each location section must have an anchor ID (e.g.,
id="saarbrucken") - The anchor ID must match the
linkvalue in the sidebar.yml (step 1) - Add your location to the "Skip to:" navigation list at the top
If you're adding the first post-mortem for a year (e.g., 2026):
-
Create the year's post-mortem.md file:
touch 2026/post-mortem.md
-
Add the front matter and structure:
--- title: "Post-Mortems" subtitle: "A collection of post-mortems" layout: about --- <h2 class="display-4">Summer Institutes in Computational Social Science 2026 Post-mortem</h2> **Published on:** December 1, 2026 [Introduction...] Skip to: - [SICSS-YourLocation](#yourlocation) <h2 class="display-4" id="yourlocation">SICSS-YourLocation</h2> [Your post-mortem content here]
-
Create your location's post_mortem.yml:
touch _data/2026/yourlocation/post_mortem.yml
-
Add title to post_mortem.yml:
- title: "Post-Mortem"
-
Update your location's sidebar.yml: Add the post-mortem link (see Required Files section above)
If the year's post-mortem.md file already exists:
-
Create your location's post_mortem.yml:
touch _data/{year}/{yourlocation}/post_mortem.yml -
Add title to post_mortem.yml:
- title: "Post-Mortem"
-
Update your location's sidebar.yml: Add the post-mortem link with the correct anchor
-
Edit the year's post-mortem.md:
- Add your location to the "Skip to:" list
- Add a new section with an anchor ID:
<h2 class="display-4" id="yourlocation">SICSS-YourLocation</h2> [Your post-mortem content]
A good post-mortem typically includes:
-
Outreach and Application Process
- How you advertised the institute
- Number of applications received
- Selection criteria and process
-
Pre-arrival and Onboarding
- Communication with participants
- Preparatory materials provided
- Technical setup
-
First Week
- Schedule structure
- Lectures and workshops
- What worked well
- What could be improved
-
Second Week / Group Projects
- Project formation process
- Support provided to teams
- Final presentations
- Outcomes
-
Post-departure
- Feedback collection
- Follow-up with participants
- Lessons learned for next time
- Be honest: Share both successes and challenges
- Be specific: Include concrete examples and numbers
- Be helpful: Focus on actionable insights for future organizers
- Be concise: While detailed, avoid unnecessary verbosity
- Include feedback: Quote or summarize participant feedback when relevant
- Short post-mortem: 500-1000 words
- Standard post-mortem: 1000-2000 words
- Detailed post-mortem: 2000-4000 words
Check these items:
- ✅ Does
_data/{year}/{location}/post_mortem.ymlexist? - ✅ Does it have a
titlefield? - ✅ Does
{year}/post-mortem.mdexist? - ✅ Does the anchor ID in post-mortem.md match the
linkvalue in sidebar.yml? - ✅ Is the location added to the "Skip to:" list?
- ✅ Have you committed and pushed all three files?
Issue: The sidebar link jumps to the wrong location or doesn't jump at all.
Solution: Ensure the link value in sidebar.yml matches the id attribute in the post-mortem.md file exactly (case-sensitive).
Example:
- sidebar.yml:
link: '#saarbrucken' - post-mortem.md:
<h2 class="display-4" id="saarbrucken">
Issue: The year's post-mortem.md file doesn't exist or is in the wrong location.
Solution: Create the file at {year}/post-mortem.md (not in a subdirectory).

If you encounter issues:
- Review this guide carefully
- Check the README.md file in the repository root for additional context
- Look at existing post-mortems as examples (e.g., 2024/post-mortem.md)
- Open an issue on GitHub with details about your problem
- Contact the SICSS technical team
- Main README - General repository documentation
- 2024 Post-Mortems - Example of a complete post-mortem page
- Jekyll Documentation - For understanding the site structure
- Markdown Guide - For formatting your content
When adding a post-mortem, make sure you:
- Create
_data/{year}/{location}/post_mortem.ymlwith a title - Update
_data/{year}/{location}/sidebar.ymlwith post-mortem link - Create or update
{year}/post-mortem.mdwith your content - Use matching anchor IDs between sidebar.yml and post-mortem.md
- Add your location to the "Skip to:" navigation
- Write a comprehensive report with lessons learned
- Commit and push all changes
- Verify the post-mortem appears correctly on the website
