+# 📚 GitHub Pages Deployment Guide for splikit
+
+## Overview
+This guide will help you deploy the pkgdown documentation site to GitHub Pages.
+
+## 🚀 Deployment Steps
+
+### Step 1: Push Changes to GitHub
+```bash
+# Add all changes
+git add .
+
+# Commit (if you haven't already)
+git commit -m "Ready for pkgdown deployment"
+
+# Push to your branch
+git push origin version_2
+
+# If version_2 is not your default branch, merge to main
+git checkout main
+git merge version_2
+git push origin main
+```
+
+### Step 2: Enable GitHub Actions (if not already enabled)
+1. Go to your repository: https://github.com/Arshammik/splikit
+2. Click on **Actions** tab
+3. If prompted, enable GitHub Actions for the repository
+
+### Step 3: Configure GitHub Pages
+1. Go to **Settings** → **Pages** (left sidebar)
+2. Under **Source**, select: **Deploy from a branch**
+3. Under **Branch**, select: **gh-pages**
+4. Under **Folder**, select: **/ (root)**
+5. Click **Save**
+
+### Step 4: Trigger the Build
+The pkgdown site will build automatically when you:
+- Push to main/master branch
+- Create a release
+- Manually trigger (Actions tab → pkgdown → Run workflow)
+
+To manually trigger:
+1. Go to **Actions** tab
+2. Select **pkgdown** workflow
+3. Click **Run workflow** → **Run workflow**
+
+### Step 5: Monitor the Build
+1. Go to **Actions** tab
+2. Click on the running workflow
+3. Watch the progress (takes 3-5 minutes)
+4. ✅ Green checkmark = Success!
+
+### Step 6: Access Your Site
+Once deployed, your site will be available at:
+**https://arshammik.github.io/splikit/**
+
+First deployment may take 5-10 minutes to become visible.
+
+## 🔧 Troubleshooting
+
+### If the build fails:
+1. Check the Actions tab for error messages
+2. Common issues:
+   - **"No such file or directory"**: The .nojekyll file should fix this
+   - **"Articles not found"**: We've removed articles section
+   - **"Package won't install"**: Check DESCRIPTION dependencies
+
+### If the site doesn't appear:
+1. Check Settings → Pages to ensure it's enabled
+2. Wait 10 minutes (first deployment can be slow)
+3. Try: https://arshammik.github.io/splikit/index.html
+4. Clear browser cache (Ctrl+Shift+R or Cmd+Shift+R)
+
+### To rebuild the site:
+```bash
+# Make changes to documentation
+# Then commit and push
+git add .
+git commit -m "Update documentation"
+git push origin main
+
+# The GitHub Action will automatically rebuild
+```
+
+## 📁 File Structure
+
+Your repository now has:
+```
+splikit/
+├── .github/
+│   └── workflows/
+│       └── pkgdown.yaml    # Builds and deploys site
+├── _pkgdown.yml            # Site configuration
+├── .nojekyll              # Prevents Jekyll processing
+├── docs/                  # Will contain built site (on gh-pages branch)
+└── vignettes/             # Your documentation
+```
+
+## 🎨 Customization
+
+To customize the site appearance, edit `_pkgdown.yml`:
+```yaml
+template:
+  bootstrap: 5
+  bootswatch: cosmo  # Try: cerulean, cosmo, flatly, journal, etc.
+  theme: github-light  # or github-dark
+```
+
+## 📋 Checklist
+
+- [ ] Push all changes to GitHub
+- [ ] GitHub Actions is enabled
+- [ ] pkgdown workflow runs successfully
+- [ ] GitHub Pages is configured for gh-pages branch
+- [ ] Site is accessible at https://arshammik.github.io/splikit/
+
+## 🔗 Useful Links
+
+- **Your Site**: https://arshammik.github.io/splikit/
+- **Repository**: https://github.com/Arshammik/splikit
+- **Actions**: https://github.com/Arshammik/splikit/actions
+- **Settings**: https://github.com/Arshammik/splikit/settings/pages
+
+## 💡 Tips
+
+1. **Local Preview**: Build locally before pushing
+   ```r
+   pkgdown::build_site()
+   # Open docs/index.html in browser
+   ```
+
+2. **Update Only Reference**: For quick updates
+   ```r
+   pkgdown::build_reference()
+   ```
+
+3. **Check Configuration**:
+   ```r
+   pkgdown::check_pkgdown()
+   ```
+
+## 📝 Notes
+
+- The site rebuilds automatically on every push to main
+- The gh-pages branch is managed automatically by GitHub Actions
+- Don't edit the gh-pages branch directly
+- The .nojekyll file ensures proper deployment without Jekyll
+
+---
+
+Good luck with your deployment! 🎉

+# 🔧 GitHub Pages Configuration Fix
+
+## The Problem
+Your repository has conflicting GitHub Pages workflows:
+1. Default Jekyll workflow (causing the error)
+2. Our pkgdown workflow (what we want)
+
+## ✅ Solution Steps
+
+### Step 1: Disable Jekyll Workflow
+1. Go to: https://github.com/Arshammik/splikit/settings/pages
+2. Under **Build and deployment**:
+   - Change from: **Deploy from a branch**
+   - Change to: **GitHub Actions**
+3. Save changes
+
+### Step 2: Push Changes
+```bash
+git push origin version_2
+```
+
+### Step 3: Monitor Deployment
+1. Go to: https://github.com/Arshammik/splikit/actions
+2. You should see "Deploy static content to Pages" workflow
+3. Wait for green checkmark (3-5 minutes)
+
+### Step 4: Verify Site
+Visit: https://arshammik.github.io/splikit/
+
+## 🎯 What Changed
+
+### Old Setup (Causing Errors):
+```
+GitHub Pages → Jekyll → Try to build from docs/ → FAIL (no Jekyll files)
+```
+
+### New Setup (Fixed):
+```
+GitHub Actions → Build pkgdown → Upload artifact → Deploy to Pages → SUCCESS
+```
+
+## 📝 Key Files
+
+1. **`.github/workflows/deploy-pages.yml`**: New workflow using GitHub Pages Action
+2. **`.nojekyll`**: Tells GitHub not to use Jekyll
+3. **`docs/.nojekyll`**: Additional safety to prevent Jekyll
+4. **`_pkgdown.yml`**: Clean configuration without articles
+
+## 🚨 Important Settings Change
+
+**You MUST change the GitHub Pages source from "Deploy from a branch" to "GitHub Actions"**
+
+This is done in:
+Settings → Pages → Build and deployment → Source → **GitHub Actions**
+
+## 🔍 How to Verify It's Working
+
+After deployment, check:
+1. No Jekyll errors in Actions tab
+2. Site loads at https://arshammik.github.io/splikit/
+3. Logo appears correctly sized
+4. All function documentation is accessible
+
+## 📊 Expected Workflow Output
+
+The "Deploy static content to Pages" workflow should show:
+- ✅ Checkout
+- ✅ Setup R
+- ✅ Setup dependencies
+- ✅ Build pkgdown site
+- ✅ Upload artifact
+- ✅ Deploy to GitHub Pages
+
+## 🛠️ If Issues Persist
+
+1. **Clear GitHub Pages cache**:
+   - Settings → Pages → ... → Unpublish site
+   - Wait 5 minutes
+   - Re-enable with GitHub Actions source
+
+2. **Force rebuild**:
+   ```bash
+   git commit --allow-empty -m "Trigger rebuild"
+   git push origin version_2
+   ```
+
+3. **Check workflow permissions**:
+   - Settings → Actions → General
+   - Workflow permissions: Read and write permissions
+   - Allow GitHub Actions to create and approve pull requests
+
+## ✨ Benefits of This Approach
+
+- No Jekyll processing (faster)
+- Direct static site deployment
+- Same method used by major R packages
+- Automatic artifact caching
+- Better error messages
+
+---
+
+This configuration matches what dplyr, ggplot2, and other tidyverse packages use for their documentation sites.
