+# 404 Error Fix Summary
+
+## Problem Statement
+The GitHub Pages site was experiencing 404 errors when accessing tools and category pages via URLs with trailing slashes (e.g., `/categories/heat/`, `/tools/`, `/about/`).
+
+## Root Cause
+Jekyll was generating pages as `.html` files (e.g., `categories/heat.html`, `about.html`) while all links throughout the site pointed to directories with trailing slashes (e.g., `/categories/heat/`, `/about/`). GitHub Pages expects to find `index.html` files within directories when accessing URLs with trailing slashes.
+
+## Solution
+Added `permalink` front matter to all affected pages to instruct Jekyll to generate them as directories containing `index.html` files.
+
+## Changes Made
+
+### 1. Category Pages (8 files)
+Added `permalink: /categories/{name}/` to each category file:
+- `categories/heat.md` → `/categories/heat/index.html`
+- `categories/flood.md` → `/categories/flood/index.html`
+- `categories/coastal.md` → `/categories/coastal/index.html`
+- `categories/green.md` → `/categories/green/index.html`
+- `categories/planning.md` → `/categories/planning/index.html`
+- `categories/data.md` → `/categories/data/index.html`
+- `categories/energy.md` → `/categories/energy/index.html`
+- `categories/other.md` → `/categories/other/index.html`
+
+### 2. Main Pages (3 files)
+Added permalinks to main content pages:
+- `about.md`: `permalink: /about/`
+- `tools.md`: `permalink: /tools/`
+- `case-studies.md`: `permalink: /case-studies/`
+
+### 3. Build Configuration
+- **Gemfile**: Added required Jekyll dependencies
+  - jekyll-theme-minimal
+  - jekyll-feed
+  - jekyll-seo-tag
+  - jekyll-sitemap
+  - kramdown-parser-gfm
+
+- **.gitignore**: Created to exclude build artifacts
+  - _site/
+  - .sass-cache/
+  - .jekyll-cache/
+  - vendor/bundle/
+  - Gemfile.lock
+
+- **_config.yml**: Cleaned up duplicate `defaults` section
+
+## Testing Results
+All pages tested locally and confirmed to return HTTP 200:
+- ✅ All 8 category pages
+- ✅ About page
+- ✅ Tools listing page
+- ✅ Case studies listing page
+- ✅ Individual tool pages (e.g., climate-central)
+- ✅ Individual case study pages
+

+    │   └── index.html
+    └── other/
+        └── index.html
+```
+
+## Deployment Notes
+1. GitHub Pages will automatically rebuild the site when changes are pushed to the main branch
+2. No additional configuration is required on the GitHub Pages settings
+3. The baseurl is already correctly configured as `/Urban-Climate-Tools`
+4. All internal links use the `{{ site.baseurl }}` variable for proper routing
+
+## Verification Steps for Live Site
+After deployment, verify these URLs work correctly:
+1. https://mk-ws-git.github.io/Urban-Climate-Tools/
+2. https://mk-ws-git.github.io/Urban-Climate-Tools/about/
+3. https://mk-ws-git.github.io/Urban-Climate-Tools/tools/
+4. https://mk-ws-git.github.io/Urban-Climate-Tools/case-studies/
+5. https://mk-ws-git.github.io/Urban-Climate-Tools/categories/heat/
+6. https://mk-ws-git.github.io/Urban-Climate-Tools/categories/flood/
+7. https://mk-ws-git.github.io/Urban-Climate-Tools/tools/climate-central/
+
+## Security Notes
+No security vulnerabilities were introduced. Changes are limited to:
+- Front matter updates (permalinks)
+- Configuration file cleanup
+- Dependency updates (standard Jekyll plugins)
+
