+3. Run `git status` and `git diff --staged`. If nothing staged, ask what to stage.
+4. Follow the commit message convention from CONTRIBUTING.md: pick the correct **type** and **scope**, write a concise imperative description.
+5. Body (if needed): explain **why**, not what.
+6. Run `make format` or `./Tools/astyle/fix_code_style.sh <file>` on changed C/C++ files before committing.
+7. Check if GPG signing is available: `git config --get user.signingkey`. If set, use `git commit -S -s`. Otherwise, use `git commit -s`.

+description: Rebase a branch onto main, handling squash-merged parent branches cleanly
+argument-hint: "[optional: branch name, defaults to current branch]"
+allowed-tools: Bash, Read, Glob, Grep, Agent
+---
+
+# Rebase Branch onto Main
+
+Rebase the current (or specified) branch onto `main`, correctly handling the case where the branch was built on top of another branch that has since been squash-merged into `main`.
+
+## Background
+
+When a parent branch is squash-merged, its individual commits become a single new commit on `main` with a different hash. A normal `git rebase main` will try to replay the parent's original commits, causing messy conflicts. The fix is to **cherry-pick only the commits unique to this branch** onto a fresh branch from `main`.
+
+## Steps
+
+1. **Identify the branch.** Use `$ARGUMENTS` if provided, otherwise use the current branch.
+
+2. **Fetch and update main:**
+   ```
+   git fetch origin main:main
+   ```
+
+3. **Find the merge base** between the branch and `main`:
+   ```
+   git merge-base <branch> main
+   ```
+
+4. **List all commits** on the branch since the merge base:
+   ```
+   git log --oneline <merge-base>..<branch>
+   ```
+
+5. **Identify which commits are unique to this branch** vs. inherited from a parent branch. Look for:
+   - Squash-merged commits on `main` that correspond to a group of commits at the bottom of the branch's history (check PR titles, commit message keywords).
+   - The boundary commit: the first commit that belongs to *this* branch's work, not the parent's.
+   - If ALL commits are unique (no parent branch), just do a normal `git rebase main` and skip the rest.
+
+6. **Create a fresh branch from `main`:**
+   ```
+   git checkout -b <branch>-rebase main
+   ```
+
+7. **Cherry-pick only the unique commits** (oldest first):
+   ```
+   git cherry-pick <first-unique-commit>^..<branch>
+   ```
+   The `A^..B` range means "from the parent of A through B inclusive."
+
+8. **Handle conflicts** if any arise during cherry-pick. Resolve and `git cherry-pick --continue`.
+
+9. **Replace the old branch:**
+   ```
+   git branch -m <branch> <branch>-old
+   git branch -m <branch>-rebase <branch>
+   ```
+
+10. **Verify** the result:
+    ```
+    git log --oneline main..<branch>
+    ```
+    Confirm only the expected commits are present.
+
+11. **Ask the user** before force-pushing. When approved:
+    ```
+    git push origin <branch> --force-with-lease
+    ```
+
+12. **Clean up** the old branch:
+    ```
+    git branch -D <branch>-old
+    ```

+# Review Guidelines docs/en Tree
+
+## File System & Structure
+
+- **Naming:** Use `lowercase_with_underscores` for all filenames. No spaces.
+- **Hierarchy:** Markdown files must reside exactly in a first-level category folder. 
+  - Valid: `docs/en/category/file.md`
+  - Invalid: `docs/en/category/subcategory/file.md`
+- **Text Files:** Any `.txt` or `.text` files must start with an underscore (e.g., `_notes.txt`).
+- **Assets:** All images/non-docs must be in `/docs/assets/`. Deep nesting is permitted here.
+- **Formats:** Prefer **SVG** for diagrams and **PNG** for screenshots. Flag JPG files.
+
+## Markdown & Style
+
+- **Headings:** Use Title Case ("First Letter Capitalisation"). 
+  - The Page Title must be the only H1 (`#`). All others must be `##` or lower.
+  - Do not apply bold or italic styling inside a heading.
+- **Formatting:** 
+  - **Bold:** Only for UI elements (buttons, menu items).
+  - **Inline Code:** Use backticks for file paths, parameters, and CLI commands (e.g., `prettier`).
+    Backticks are optional for hyperlinked CLI commands and tool names.
+  - **Italics (Emphasis):** Use for application names (e.g., *QGroundControl*).
+    Emphasis is optional for hyperlinked applications.
+- **Structure:** End every line at the end of a sentence (Semantic Line Breaks).
+
+## Linking & Navigation
+
+- **Standard Links:** Use standard inline syntax: `[link text](../category/filename.md)`.
+  Note relative link. 
+- **Table Links:** To keep tables readable, use reference-style links.
+  - Definition: `[Link Name]: https://example.com` (placed below the table).
+  - Usage: `[Link Name]` within the table cell.
+- **Images:** All image links must include a descriptive, accessible alt-text in the brackets: `![Detailed description of the image content](../../assets/path/to/image.png)`.
+  Note that all images should be relative references to images stored in the assets folder, which should be two folders below the any markdown file (as they are stored in a "category" subfolder) 
+
+- **Standard Links:** Use standard inline syntax: `[link text](../category/filename.md)`. Note the use of relative links.
+- **Table Links:** To keep tables easier to edit, prefer reference-style links.
+  - Definition: `[Link Name]: https://example.com` (placed below the table).
+  - Usage: `[Link Name]` within the table cell.
+- **Images:** All image links must include a descriptive, accessible alt-text: `![Detailed description of the image content](../../assets/path/to/image.png)`.
+  - **Note:** All images must be relative references to the `/docs/assets/` folder. Since documents are nested in a category folder, this is usually two levels up (`../../assets/`).
+
+## Quality Control
+
+- **Prettier Check:** Ensure Prettier rules have been applied. If there is evidence of inconsistent indentation or spacing, request the author run `npx prettier --write .` before merging.
+- **Language:** Enforce **UK English** spelling and grammar.

-### Commit your changes
+### Coding standards
 
-Always write descriptive commit messages and add a fixes or relates note to them with an [issue number](https://github.com/px4/Firmware/issues) (Github will link these then conveniently)
+All C/C++ code must follow the [PX4 coding style](https://docs.px4.io/main/en/contribute/code.html). Formatting is enforced by [astyle](http://astyle.sourceforge.net/) in CI (`make check_format`). Code quality checks run via [clang-tidy](https://clang.llvm.org/extra/clang-tidy/). Pull requests that fail either check will not be merged.

+## Commit message convention
+
+PX4 uses [conventional commits](https://www.conventionalcommits.org/) for all commit messages and PR titles.
+
+### Format

-Change how the attitude controller works
-
-- Fixes rate feed forward
-- Allows a local body rate override
-
-Fixes issue #123
+type(scope): short description of the change
 ```
 
-### Test your changes
+| Part | Rule |
+|------|------|
+| **type** | Category of change (see types table below) |
+| **scope** | The module, driver, board, or area of PX4 affected |
+| **`!`** (optional) | Append before `:` to mark a breaking change |
+| **description** | What the change does, at least 5 characters, written in imperative form |
 
-Since we care about safety, we will regularly ask you for test results. Best is to do a test flight (or bench test where it applies) and upload the logfile from it (on the microSD card in the logs directory) to Google Drive or Dropbox and share the link.
+### Types
 
-### Push your changes
+| Type | Description |
+|------|-------------|

+| `docs` | Documentation only changes |
+| `style` | Formatting, whitespace, no code change |
+| `refactor` | Code change that neither fixes a bug nor adds a feature |
+| `perf` | Performance improvement |
+| `test` | Adding or correcting tests |
+| `build` | Build system or external dependencies |
+| `ci` | CI configuration files and scripts |

-Push changes to your repo and send a [pull request](https://github.com/PX4/Firmware/compare/).
+### Scopes
+
+The scope identifies which part of PX4 is affected. Common scopes:
+
+| Scope | Area |
+|-------|------|
+| `ekf2` | Extended Kalman Filter (state estimation) |
+| `mavlink` | MAVLink messaging protocol |
+| `commander` | Commander and mode management |
+| `navigator` | Mission, RTL, Land, and other navigation modes |
+| `sensors` | Sensor drivers and processing |
+| `drivers` | Hardware drivers |
+| `boards/px4_fmu-v6x` | Board-specific changes (use the board name) |
+| `mc_att_control` | Multicopter attitude control |
+| `mc_pos_control` | Multicopter position control |
+| `fw_att_control` | Fixed-wing attitude control |
+| `vtol` | VTOL-specific logic |
+| `actuators` | Mixer and actuator output |
+| `battery` | Battery monitoring and estimation |
+| `logger` | On-board logging |
+| `param` | Parameter system |
+| `simulation` | SITL, Gazebo, SIH |
+| `ci` | Continuous integration and workflows |
+| `docs` | Documentation |
+| `build` | CMake, toolchain, build system |
+| `uorb` | Inter-module messaging |
+
+For changes spanning multiple subsystems, use the primary one affected. Look at the directory path of the files you changed to find the right scope: `src/modules/ekf2/` uses `ekf2`, `src/drivers/imu/` uses `drivers/imu`, `.github/workflows/` uses `ci`.
+
+### Breaking changes
+
+Append `!` before the colon to indicate a breaking change:
+
+```
+feat(ekf2)!: remove deprecated height fusion API
+```
+
+### Good commit messages
+
+```
+feat(ekf2): add height fusion timeout
+fix(mavlink): correct BATTERY_STATUS_V2 parsing
+refactor(navigator): simplify RTL altitude logic
+ci(workflows): migrate to reusable workflows
+docs(ekf2): update tuning guide
+feat(boards/px4_fmu-v6x)!: remove deprecated driver API
+perf(mc_rate_control): reduce loop latency
+```
+
+### Commits to avoid
+
+These will be flagged by CI and should be squashed or reworded before merging:
+
+```
+fix                                    # too vague, no type or scope
+update                                 # too vague, no type or scope
+ekf2: fix something                   # missing type prefix
+apply suggestions from code review     # squash into parent commit
+do make format                         # squash into parent commit
+WIP: trying something                  # not ready for main
+oops                                   # not descriptive
+```
+
+### PR titles
+
+The PR title follows the same `type(scope): description` format. This is enforced by CI and is especially important because the PR title becomes the commit message when a PR is squash-merged.
+
+### Merge policy
+
+Commits should be atomic and independently revertable. Squash at reviewer discretion for obvious cases (multiple WIP commits, messy review-response history). When your commits are clean and logical, they will be preserved as individual commits on `main`.
+
+### Cleaning up commits
+
+If CI flags your commit messages, you can fix them with an interactive rebase:
+
+```bash
+# Squash all commits into one:
+git rebase -i HEAD~N   # replace N with the number of commits
+# mark all commits except the first as 'squash' or 'fixup'
+# reword the remaining commit to follow the format
+git push --force-with-lease
+
+# Or reword specific commits:
+git rebase -i HEAD~N
+# mark the bad commits as 'reword'
+git push --force-with-lease
+```
+
+## Test your changes
+
+PX4 is safety-critical software. All contributions must include adequate testing where practical:
+
+- **New features** must include unit tests and/or integration tests that exercise the new functionality, where practical. Hardware-dependent changes that cannot be tested in SITL should include bench test or flight test evidence.
+- **Bug fixes** must include a regression test where practical. When automated testing is not feasible (hardware-specific issues, race conditions, etc.), provide a link to a flight log demonstrating the fix and the reproduction steps for the original bug.
+- **Reviewers** will verify that tests or test evidence exist before approving a pull request.
+
+### Types of tests
+
+| Test type | When to use | How to run |
+|-----------|-------------|------------|
+| **Unit tests** (gtest) | Module-level logic, math, parsing | `make tests` |
+| **SITL integration tests** (MAVSDK) | Flight behavior, failsafes, missions | `test/mavsdk_tests/` |
+| **Bench tests / flight logs** | Hardware-dependent changes | Upload logs to [Flight Review](https://logs.px4.io) |
+
+Since we care about safety, we will regularly ask you for test results. Best is to do a test flight (or bench test where it applies) and upload the log file from it (on the microSD card in the logs directory) to Google Drive or Dropbox and share the link.

+---
 
-This repository holds the [PX4](http://px4.io) flight control solution for drones, with the main applications located in the [src/modules](https://github.com/PX4/PX4-Autopilot/tree/main/src/modules) directory. It also contains the PX4 Drone Middleware Platform, which provides drivers and middleware to run drones.
+## About
 
-PX4 is highly portable, OS-independent and supports Linux, NuttX and MacOS out of the box.
+PX4 is an open-source autopilot stack for drones and unmanned vehicles. It supports multirotors, fixed-wing, VTOL, rovers, and many more experimental platforms from racing quads to industrial survey aircraft. It runs on [NuttX](https://nuttx.apache.org/), Linux, and macOS. Licensed under [BSD 3-Clause](LICENSE).
 
-* Official Website: http://px4.io (License: BSD 3-clause, [LICENSE](https://github.com/PX4/PX4-Autopilot/blob/main/LICENSE))
-* [Supported airframes](https://docs.px4.io/main/en/airframes/airframe_reference.html) ([portfolio](https://px4.io/ecosystem/commercial-systems/)):
-  * [Multicopters](https://docs.px4.io/main/en/frames_multicopter/)
-  * [Fixed wing](https://docs.px4.io/main/en/frames_plane/)
-  * [VTOL](https://docs.px4.io/main/en/frames_vtol/)
-  * [Autogyro](https://docs.px4.io/main/en/frames_autogyro/)
-  * [Rover](https://docs.px4.io/main/en/frames_rover/)
-  * many more experimental types (Blimps, Boats, Submarines, High Altitude Balloons, Spacecraft, etc)
-* Releases: [Downloads](https://github.com/PX4/PX4-Autopilot/releases)
+## Why PX4
 
-## Releases
+**Modular architecture.** PX4 is built around [uORB](https://docs.px4.io/main/en/middleware/uorb.html), a [DDS](https://docs.px4.io/main/en/middleware/uxrce_dds.html)-compatible publish/subscribe middleware. Modules are fully parallelized and thread safe. You can build custom configurations and trim what you don't need.
 
-Release notes and supporting information for PX4 releases can be found on the [Developer Guide](https://docs.px4.io/main/en/releases/).
+**Wide hardware support.** PX4 runs on a wide range of [autopilot boards](https://docs.px4.io/main/en/flight_controller/) and supports an extensive set of sensors, telemetry radios, and actuators through the [Pixhawk](https://pixhawk.org/) ecosystem.
 
-## Building a PX4 based drone, rover, boat or robot
+**Developer friendly.** First-class support for [MAVLink](https://mavlink.io/) and [DDS / ROS 2](https://docs.px4.io/main/en/ros2/) integration. Comprehensive [SITL simulation](https://docs.px4.io/main/en/simulation/), hardware-in-the-loop testing, and [log analysis](https://docs.px4.io/main/en/log/flight_log_analysis.html) tools. An active developer community on [Discord](https://discord.gg/dronecode) and the [weekly dev call](https://docs.px4.io/main/en/contribute/).
 
-The [PX4 User Guide](https://docs.px4.io/main/en/) explains how to assemble [supported vehicles](https://docs.px4.io/main/en/airframes/airframe_reference.html) and fly drones with PX4. See the [forum and chat](https://docs.px4.io/main/en/#getting-help) if you need help!
+**Vendor neutral governance.** PX4 is hosted under the [Dronecode Foundation](https://www.dronecode.org/), part of the Linux Foundation. Business-friendly BSD-3 license. No single vendor controls the roadmap.

-This [Developer Guide](https://docs.px4.io/main/en/development/development.html) is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
+<sub>…and many more: helicopters, autogyros, airships, submarines, boats, and other experimental platforms. These frames have basic support but are not part of the regular flight-test program. See the <a href="https://docs.px4.io/main/en/airframes/airframe_reference.html">full airframe reference</a>.</sub>
 
-Developers should read the [Guide for Contributions](https://docs.px4.io/main/en/contribute/).
-See the [forum and chat](https://docs.px4.io/main/en/#getting-help) if you need help!
+## Quick Start
 
+```bash
+git clone https://github.com/PX4/PX4-Autopilot.git --recursive
+cd PX4-Autopilot
+make px4_sitl

-## Weekly Dev Call
+> [!NOTE]
+> See the [Development Guide](https://docs.px4.io/main/en/development/development.html) for toolchain setup and build options.
 
-The PX4 Dev Team syncs up on a [weekly dev call](https://docs.px4.io/main/en/contribute/).
+## Documentation & Resources
 
-> **Note** The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the [Dronecode calendar](https://www.dronecode.org/calendar/).
