+# CI Optimization Patterns
+
+Strategies for efficient CI/CD with Turborepo.
+
+## PR vs Main Branch Builds
+
+### PR Builds: Only Affected
+
+Test only what changed in the PR:
+
+```yaml
+- name: Test (PR)
+  if: github.event_name == 'pull_request'
+  run: turbo run build test --affected
+```
+
+### Main Branch: Full Build
+
+Ensure complete validation on merge:
+
+```yaml
+- name: Test (Main)
+  if: github.ref == 'refs/heads/main'
+  run: turbo run build test
+```
+
+## Custom Git Ranges with --filter
+
+For advanced scenarios, use `--filter` with git refs:
+
+```bash
+# Changes since specific commit
+turbo run test --filter="...[abc123]"
+
+# Changes between refs
+turbo run test --filter="...[main...HEAD]"
+
+# Changes in last 3 commits
+turbo run test --filter="...[HEAD~3]"
+```
+
+## Caching Strategies
+
+### Remote Cache (Recommended)
+
+Best performance - shared across all CI runs and developers:
+
+```yaml
+env:
+  TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
+  TURBO_TEAM: ${{ vars.TURBO_TEAM }}
+```
+
+### actions/cache Fallback
+
+When remote cache isn't available:
+
+```yaml
+- uses: actions/cache@v4
+  with:
+    path: .turbo
+    key: turbo-${{ runner.os }}-${{ github.sha }}
+    restore-keys: |
+      turbo-${{ runner.os }}-${{ github.ref }}-
+      turbo-${{ runner.os }}-
+```
+
+Limitations:
+
+- Cache is branch-scoped
+- PRs restore from base branch cache
+- Less efficient than remote cache
+
+## Matrix Builds
+
+Test across Node versions:
+
+```yaml
+strategy:
+  matrix:
+    node: [18, 20, 22]
+
+steps:
+  - uses: actions/setup-node@v4
+    with:
+      node-version: ${{ matrix.node }}
+
+  - run: turbo run test
+```
+
+## Parallelizing Across Jobs
+
+Split tasks into separate jobs:
+
+```yaml
+jobs:
+  lint:
+    runs-on: ubuntu-latest
+    steps:
+      - run: turbo run lint --affected
+
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - run: turbo run test --affected
+
+  build:
+    runs-on: ubuntu-latest
+    needs: [lint, test]
+    steps:
+      - run: turbo run build
+```
+
+### Cache Considerations
+
+When parallelizing:
+
+- Each job has separate cache writes
+- Remote cache handles this automatically
+- With actions/cache, use unique keys per job to avoid conflicts
+
+```yaml
+- uses: actions/cache@v4
+  with:
+    path: .turbo
+    key: turbo-${{ runner.os }}-${{ github.job }}-${{ github.sha }}
+```
+
+## Conditional Tasks
+
+Skip expensive tasks on draft PRs:
+
+```yaml
+- name: E2E Tests
+  if: github.event.pull_request.draft == false
+  run: turbo run test:e2e --affected
+```
+
+Or require label for full test:
+
+```yaml
+- name: Full Test Suite
+  if: contains(github.event.pull_request.labels.*.name, 'full-test')
+  run: turbo run test
+```
