+
+## ⚠️ Pipeline Status: Failed (Expected)
+
+**Pipeline #205** failed immediately because:
+- **No GitLab Runners are configured** for the project
+
+This is **normal** for a new GitLab installation. You need to set up a Runner first.
+
+---
+
+## 🔧 Next Step: Configure GitLab Runner
+
+### Option 1: Register a New Runner
+
+**On your GitLab server (or dedicated runner machine):**
+
+```bash
+# Install GitLab Runner (if not already installed)
+curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash
+sudo apt-get install gitlab-runner
+
+# Register the runner
+sudo gitlab-runner register \
+  --url https://gitlab.silverlabs.uk \
+  --token <PROJECT_REGISTRATION_TOKEN> \
+  --executor docker \
+  --docker-image mingc/android-build-box:latest \
+  --description "Android Build Runner" \
+  --tag-list "android,docker" \
+  --run-untagged=true \
+  --locked=false
+```
+
+**Get the registration token:**
+1. Go to: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/settings/ci_cd
+2. Expand "Runners"
+3. Copy the registration token
+4. Use it in the command above
+
+### Option 2: Use an Existing Runner
+
+If you already have GitLab Runners:
+
+1. Go to: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/settings/ci_cd
+2. Expand "Runners"
+3. Find "Available specific runners"
+4. Click "Enable" for an existing runner
+
+### Option 3: Use Shared Runners (If Available)
+
+If your GitLab instance has shared runners:
+
+1. Go to: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/settings/ci_cd
+2. Expand "Runners"
+3. Enable "Shared runners"
+
+---
+
+## 🚀 After Runner is Configured
+
+### Trigger a New Pipeline
+
+**Option A: Push a new commit**
+```bash
+cd /mnt/c/Production/Source/SilverLABS/SilverDROID
+echo "# Trigger pipeline" >> README.md
+git add README.md
+git commit -m "Trigger CI/CD pipeline with runner"
+git push origin main
+```
+
+**Option B: Manual trigger via Web UI**
+1. Go to: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/pipelines
+2. Click "Run pipeline"
+3. Select "main" branch
+4. Click "Run pipeline"
+
+**Option C: API trigger**
+```bash
+curl -X POST "https://gitlab.silverlabs.uk/api/v4/projects/10/pipeline" \
+  --header "PRIVATE-TOKEN: glpat-wqUcD7mg53F1mgM-N-PdiW86MQp1OjEH.01.0w074ox93" \
+  --data "ref=main"
+```
+
+### Expected Pipeline Duration
+
+Once a runner is available:
+- **prepare:** ~1 minute (download dependencies)
+- **test:** ~2 minutes (lint + unit tests)
+- **build:** ~3-5 minutes (compile APKs)
+- **deploy:** ~30 seconds (store artifacts)
+
+**Total:** ~5-8 minutes
+
+---
+
+## 📦 What You'll Get
+
+### Build Artifacts
+
+Once the pipeline completes successfully:
+
+**Debug APK:**
+- Path: `app/build/outputs/apk/debug/app-debug.apk`
+- Size: ~10-15 MB
+- Download: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/jobs/artifacts/main/raw/app/build/outputs/apk/debug/app-debug.apk?job=build:debug
+
+**Release APK:**
+- Path: `app/build/outputs/apk/release/app-release-unsigned.apk`
+- Size: ~8-10 MB
+- Download: https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/jobs/artifacts/main/raw/app/build/outputs/apk/release/app-release-unsigned.apk?job=build:release
+
+**Android App Bundle:**
+- Path: `app/build/outputs/bundle/release/app-release.aab`
+- Size: ~8-10 MB
+- For: Google Play Store submission
+
+### Test Reports
+
+- **Lint Report:** HTML + XML format
+- **Unit Tests:** JUnit XML format
+- **Security Scan:** Dependency check report
+

+
+## 📊 Current Project Status
+
+### Git Status
+- ✅ Repository initialized
+- ✅ Remote configured
+- ✅ Initial commit created
+- ✅ Pushed to GitLab
+- ✅ Project created successfully
+
+### CI/CD Status
+- ✅ `.gitlab-ci.yml` configured
+- ⚠️ **Runner needed** - Pipeline waiting for executor
+- ⏳ Pending first successful build
+
+### App Status
+- ✅ Android project complete
+- ✅ MainActivity loads admin.dark.side
+- ✅ WASM/PWA support enabled
+- ✅ Glassmorphism UI implemented
+- ⏳ APK needs to be built
+
+---
+
+## 🎯 Immediate Action Required
+
+**To get your APK, you must configure a GitLab Runner:**
+
+1. **SSH into your GitLab server:**
+   ```bash
+   ssh sysadmin@gitlab.silverlabs.uk
+   ```
+
+2. **Install GitLab Runner** (if not installed):
+   ```bash
+   curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash
+   sudo apt-get install gitlab-runner
+   ```
+
+3. **Register the runner** (see commands above)
+
+4. **Verify runner is active:**
+   ```bash
+   sudo gitlab-runner list
+   ```
+
+5. **Trigger a new pipeline** (see options above)
+
+6. **Monitor the build:**
+   ```
+   https://gitlab.silverlabs.uk/silverlabs/silverdroid/-/pipelines
+   ```
+
+7. **Download APK** once complete
+
+---
+
+## 🔄 Alternative: Build Locally
+
+If you can't configure a runner right now, build locally:
+
+### Windows PowerShell
+```powershell
+cd C:\Production\Source\SilverLABS\SilverDROID
+
+# First time: setup Gradle wrapper
+# (Download gradle-8.9-bin.zip and extract, then run gradle wrapper)
+
+# Build debug APK
+.\gradlew.bat assembleDebug
+
+# Output location
+C:\Production\Source\SilverLABS\SilverDROID\app\build\outputs\apk\debug\app-debug.apk
+```
+
+### Android Studio
+1. Open: `C:\Production\Source\SilverLABS\SilverDROID`
+2. Wait for Gradle sync
+3. Build → Build Bundle(s) / APK(s) → Build APK(s)
+4. Find APK in: `app\build\outputs\apk\debug\`
