+# GitHub Actions Workflows
+
+This directory contains automated CI/CD workflows for the INAV project.
+
+## Active Workflows
+
+### Build and Test
+
+#### `ci.yml` - Build Firmware
+**Triggers:** Pull requests, pushes to maintenance branches
+**Purpose:** Compiles INAV firmware for all targets to verify builds succeed
+**Matrix:** 15 parallel build jobs for faster CI
+
+#### `nightly-build.yml` - Nightly Builds
+**Triggers:** Scheduled nightly
+**Purpose:** Creates nightly development builds for testing
+
+### Documentation
+
+#### `docs.yml` - Documentation Build
+**Triggers:** Pull requests affecting documentation
+**Purpose:** Validates documentation builds correctly
+
+### Code Quality
+
+#### `pg-version-check.yml` - Parameter Group Version Check
+**Triggers:** Pull requests to maintenance-9.x and maintenance-10.x
+**Purpose:** Detects parameter group struct modifications and verifies version increments
+**Why:** Prevents settings corruption when struct layout changes without version bump
+
+**How it works:**
+1. Scans changed .c/.h files for `PG_REGISTER` entries
+2. Detects if associated struct typedefs were modified
+3. Checks if the PG version parameter was incremented
+4. Posts helpful comment if version not incremented
+
+**Reference:** See `docs/development/parameter_groups/` for PG system documentation
+
+**Script:** `.github/scripts/check-pg-versions.sh`
+
+**When to increment PG versions:**
+- ✅ Adding/removing fields from struct
+- ✅ Changing field types or sizes
+- ✅ Reordering fields
+- ✅ Adding/removing packing attributes
+- ❌ Only changing `PG_RESET_TEMPLATE` default values
+- ❌ Only changing comments
+
+### Pull Request Helpers
+
+#### `pr-branch-suggestion.yml` - Branch Targeting Suggestion
+**Triggers:** PRs targeting master branch
+**Purpose:** Suggests using maintenance-9.x or maintenance-10.x instead
+
+#### `non-code-change.yaml` - Non-Code Change Detection
+**Triggers:** Pull requests
+**Purpose:** Detects PRs with only documentation/formatting changes
+
+## Configuration Files
+
+- `../.github/stale.yml` - Stale issue/PR management
+- `../.github/no-response.yml` - Auto-close issues without response
+- `../.github/issue_label_bot.yaml` - Automatic issue labeling
+
+## Adding New Workflows
+
+When adding workflows:
+
+1. **Use descriptive names** - Make purpose clear from filename
+2. **Document in this README** - Add entry above with purpose and triggers
+3. **Set appropriate permissions** - Principle of least privilege
+4. **Test in fork first** - Verify before submitting to main repo
+5. **Handle errors gracefully** - Don't block CI unnecessarily
+
+### Common Patterns
+
+**Checkout with history:**
+```yaml
+- uses: actions/checkout@v4
+  with:
+    fetch-depth: 0
+```
+
+**Post PR comments:**
+```yaml
+- uses: actions/github-script@v7
+  with:
+    script: |
+      await github.rest.issues.createComment({
+        owner: context.repo.owner,
+        repo: context.repo.repo,
+        issue_number: context.issue.number,
+        body: 'Comment text'
+      });
+```
+
+**Run bash scripts:**
+```yaml
+- run: bash .github/scripts/script-name.sh
+  env:
+    GITHUB_BASE_REF: ${{ github.base_ref }}
+```
+
+## Permissions
+
+Workflows use GitHub's fine-grained permissions:
+
+- `contents: read` - Read repository code
+- `pull-requests: write` - Post/update PR comments
+- `actions: read` - Read workflow run data
+
+## Local Testing
+
+Scripts in `.github/scripts/` can be run locally:
+
+```bash
+cd inav
+export GITHUB_BASE_REF=maintenance-9.x
+export GITHUB_HEAD_REF=feature-branch
+bash .github/scripts/check-pg-versions.sh
+```

+            These are nightly builds and configuration settings can be added and removed often. Flashing with Full chip erase is strongly recommended to avoid issues.
+            Firmware related issues should be opened in the iNavflight/inav repository, not in inav-nightly.

+
+            - **\`maintenance-9.x\`** - If your change is backward-compatible and won't create compatibility issues between INAV firmware and Configurator 9.x versions. This will allow your PR to be included in the next 9.x release.
