+# Fastlane integration (optional)
+
+Fastlane automates signing, building, and uploading to TestFlight/App Store. Use it when you want single-command releases or need automated certificate management.
+
+## Install
+
+**Recommended (with Bundler):**
+```bash
+# Gemfile is in bootstrap/ template
+cd MyApp
+bundle install
+bundle exec fastlane [lane]
+```
+
+Using Bundler locks dependencies, eliminates startup warnings, and makes Fastlane launch faster. Commit `Gemfile` and `Gemfile.lock` to version control.
+
+**Alternative (Homebrew):**
+```bash
+brew install fastlane
+fastlane [lane]
+```
+
+## Initialize in project
+
+If starting fresh (not using templates):
+```bash
+cd MyApp
+bundle init
+echo 'gem "fastlane"' >> Gemfile
+bundle install
+bundle exec fastlane init
+```
+
+Select option 4 (manual setup) to avoid overwriting existing configuration.
+
+## Signing with match
+
+Tuist defines build settings but doesn't manage certificates. Fastlane's `match` stores signing assets in a private git repo.
+
+**Setup match:**
+```bash
+fastlane match init
+```
+
+**Generate certificates:**
+```bash
+fastlane match development
+fastlane match appstore
+```
+
+**Use in Fastfile:**
+```ruby
+lane :beta do
+  match(type: "appstore")
+  build_app(scheme: "MyApp", configuration: "Release")
+  upload_to_testflight
+end
+```
+
+## Minimal Fastfile
+
+Wraps existing shell scripts:
+
+```ruby
+default_platform(:ios)
+
+platform :ios do
+  desc "Build and upload to TestFlight"
+  lane :beta do
+    sh "cd .. && tuist generate"
+    sh "cd .. && Scripts/archive.sh"
+    sh "cd .. && Scripts/export_ipa.sh"
+    sh "cd .. && Scripts/upload_testflight.sh"
+  end
+
+  desc "CI build (no signing)"
+  lane :ci do
+    sh "cd .. && tuist generate"
+    sh "cd .. && SKIP_SIGNING=1 Scripts/archive.sh"
+  end
+end
+```
+
+## SwiftLint integration
+
+The included Fastfile has a `lint` lane. See `references/swiftlint.md` for setup.
+
+## Native Fastlane actions
+
+Replace shell scripts with native actions for better error handling:
+
+```ruby
+platform :ios do
+  lane :beta do
+    # Generate project
+    sh "cd .. && tuist generate"
+
+    # Build and archive
+    build_app(
+      scheme: "MyApp",
+      configuration: "Release",
+      export_method: "app-store"
+    )
+
+    # Upload to TestFlight
+    upload_to_testflight(
+      skip_waiting_for_build_processing: true
+    )
+  end
+end
+```
+
+## Environment variables
+
+Fastlane reads from `.env` files:
+
+```bash
+# fastlane/.env
+APP_IDENTIFIER=com.example.myapp
+APPLE_ID=your@email.com
+TEAM_ID=XXXXXXXXXX
+MATCH_GIT_URL=git@github.com:yourorg/certificates.git
+```
+
+## CI integration
+
+For GitHub Actions:
+
+```yaml
+- name: Install Fastlane
+  run: brew install fastlane
+
+- name: Run Fastlane
+  env:
+    MATCH_PASSWORD: ${{ secrets.MATCH_PASSWORD }}
+    APP_STORE_CONNECT_API_KEY_ID: ${{ secrets.ASC_KEY_ID }}
+    APP_STORE_CONNECT_API_KEY_ISSUER_ID: ${{ secrets.ASC_ISSUER_ID }}
+    APP_STORE_CONNECT_API_KEY_CONTENT: ${{ secrets.ASC_KEY_CONTENT }}
+  run: fastlane beta
+```
+
+## GitHub releases
+
+The included Fastfile has a `release` lane for automated GitHub releases with IPA upload:
+
+```bash
+bundle exec fastlane release version:1.2.0
+bundle exec fastlane release version:1.2.0 testflight:true
+```
+
+Required environment variables: `GITHUB_TOKEN`, `GITHUB_REPOSITORY`.
+
+## When to use Fastlane
+
+| Scenario | Recommendation |
+|----------|----------------|
+| Solo dev, manual releases | Shell scripts are sufficient |
+| Team with shared signing | Use `match` for certificate management |
+| CI/CD pipeline | Use Fastlane lanes for reproducibility |
+| Frequent TestFlight builds | Fastlane reduces manual steps |
+| Automated GitHub releases | Use `release` lane for one-command releases |
