+# How to contribute
+
+Our software is open source so you can solve your own problems without needing help from others. And if you solve a problem and are so kind, you can upstream it for the rest of the world to use.
+
+Most open source development activity is coordinated through our [Discord](https://discord.comma.ai). A lot of documentation is available on our [medium](https://medium.com/@comma_ai/)
+
+## Getting Started
+
+ * Join our [Discord](https://discord.comma.ai)
+ * Make sure you have a [GitHub account](https://github.com/signup/free)
+ * Fork [our repositories](https://github.com/commaai) on GitHub
+
+## Testing
+
+### Local Testing
+
+You can test your changes on your machine by running `run_docker_tests.sh`. This will run some automated tests in docker against your code.
+
+### Automated Testing
+
+All PRs are automatically checked by Github Actions. Check out `.github/workflows/` for what Github Actions runs. Any new tests sould be added to Github Actions.
+
+### Code Style and Linting
+
+Code is automatically checked for style by Github Actions as part of the automated tests. You can also run these tests yourself by running `pylint_openpilot.sh` and `flake8_openpilot.sh`.
+
+## Car Ports (openpilot)
+
+We've released a [Model Port guide](https://medium.com/@comma_ai/openpilot-port-guide-for-toyota-models-e5467f4b5fe6) for porting to Toyota/Lexus models.
+
+If you port openpilot to a substantially new car brand, see this more generic [Brand Port guide](https://medium.com/@comma_ai/how-to-write-a-car-port-for-openpilot-7ce0785eda84). You might also be eligible for a bounty. See our bounties at [comma.ai/bounties.html](https://comma.ai/bounties.html)
+
+## Pull Requests
+
+Pull requests should be against the master branch. Before running master on in-car hardware, you'll need to clone the submodules too. That can be done by recursively cloning the repository:
+```
+git clone https://github.com/commaai/openpilot.git --recursive
+```
+Or alternatively, when on the master branch:
+```
+git submodule init
+git submodule update
+```
+The reasons for having submodules on a dedicated repository and our new development philosophy can be found in our [post about externalization](https://medium.com/@comma_ai/a-2020-theme-externalization-13b33326d8b3).
+Modules that are in seperate repositories include:
+* apks
+* cereal
+* laika
+* opendbc
+* panda

-Welcome to openpilot
-======
+[![](https://i.imgur.com/UelUjKAh.png)](#)
 
-[openpilot](http://github.com/commaai/openpilot) is an open source driving agent.
+Table of Contents
+=======================
 
-Currently it performs the functions of Adaptive Cruise Control (ACC) and Lane Keeping Assist System (LKAS) for Hondas and Acuras. It's about on par with Tesla Autopilot at launch, and better than [all other manufacturers](http://www.thedrive.com/tech/5707/the-war-for-autonomous-driving-part-iii-us-vs-germany-vs-japan).

+What is openpilot?
 ------
 
-Right now openpilot supports the [neo research platform](http://github.com/commaai/neo) for vehicle control. We'd like to support [Open Source Car Control](https://github.com/PolySync/OSCC) as well.
+[openpilot](http://github.com/commaai/openpilot) is an open source driver assistance system. Currently, openpilot performs the functions of Adaptive Cruise Control (ACC), Automated Lane Centering (ALC), Forward Collision Warning (FCW) and Lane Departure Warning (LDW) for a growing variety of supported [car makes, models and model years](#supported-cars). In addition, while openpilot is engaged, a camera based Driver Monitoring (DM) feature alerts distracted and asleep drivers.
 
-To install it on the NEO:

+Integration with Stock Features
+------
+
+In all supported cars:
+* Stock Lane Keep Assist (LKA) and stock ALC are replaced by openpilot ALC, which only functions when openpilot is engaged by the user.
+* Stock LDW is replaced by openpilot LDW.
+
+Additionally, on specific supported cars (see ACC column in [supported cars](#supported-cars)):
+* Stock ACC is replaced by openpilot ACC.
+* openpilot FCW operates in addition to stock FCW.
+
+openpilot should preserve all other vehicle's stock features, including, but are not limited to: FCW, Automatic Emergency Braking (AEB), auto high-beam, blind spot warning, and side collision warning.
+
+Supported Hardware
+------
+
+At the moment, openpilot supports the [EON DevKit](https://comma.ai/shop/products/eon-dashcam-devkit) and the [comma two](https://comma.ai/shop/products/comma-two-devkit). A [car harness](https://comma.ai/shop/products/car-harness) is recommended to connect the EON or comma two to the car. For experimental purposes, openpilot can also run on an Ubuntu computer with external [webcams](https://github.com/commaai/openpilot/tree/master/tools/webcam).

+<sup>3</sup>Requires a [custom connector](https://community.comma.ai/wiki/index.php/Volkswagen#Integration_at_R242_Camera) for the [car harness](https://comma.ai/shop/products/car-harness) <br />
+
+Although it's not upstream, there's a community of people getting openpilot to run on Tesla's [here](https://tinkla.us/)
+
+Community Maintained Cars and Features are not verified by comma to meet our [safety model](SAFETY.md). Be extra cautious using them. They are only available after enabling the toggle in `Settings->Developer->Enable Community Features`.
+
+To promote a car from community maintained, it must meet a few requirements. We must own one from the brand, we must sell the harness for it, has full ISO26262 in both panda and openpilot, there must be a path forward for longitudinal control, it must have AEB still enabled, and it must support fingerprinting 2.0
+
+Installation Instructions
+------
+
+Install openpilot on an EON or comma two by entering ``https://openpilot.comma.ai`` during the installer setup.
+
+Follow these [video instructions](https://youtu.be/3nlkomHathI) to properly mount the device on the windshield. Note: openpilot features an automatic pose calibration routine and openpilot performance should not be affected by small pitch and yaw misalignments caused by imprecise device mounting.
+
+Before placing the device on your windshield, check the state and local laws and ordinances where you drive. Some state laws prohibit or restrict the placement of objects on the windshield of a motor vehicle.
+
+You will be able to engage openpilot after reviewing the onboarding screens and finishing the calibration procedure.
+
+Limitations of openpilot ALC and LDW
+------
+
+openpilot ALC and openpilot LDW do not automatically drive the vehicle or reduce the amount of attention that must be paid to operate your vehicle. The driver must always keep control of the steering wheel and be ready to correct the openpilot ALC action at all times.
+
+While changing lanes, openpilot is not capable of looking next to you or checking your blind spot. Only nudge the wheel to initiate a lane change after you have confirmed it's safe to do so.
+
+Many factors can impact the performance of openpilot ALC and openpilot LDW, causing them to be unable to function as intended. These include, but are not limited to:
+
+* Poor visibility (heavy rain, snow, fog, etc.) or weather conditions that may interfere with sensor operation.
+* The road facing camera is obstructed, covered or damaged by mud, ice, snow, etc.
+* Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
+* The device is mounted incorrectly.
+* When in sharp curves, like on-off ramps, intersections etc...; openpilot is designed to be limited in the amount of steering torque it can produce.
+* In the presence of restricted lanes or construction zones.
+* When driving on highly banked roads or in presence of strong cross-wind.
+* Extremely hot or cold temperatures.
+* Bright light (due to oncoming headlights, direct sunlight, etc.).
+* Driving on hills, narrow, or winding roads.
+
+The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. It is the driver's responsibility to be in control of the vehicle at all times.
+
+Limitations of openpilot ACC and FCW
+------
+
+openpilot ACC and openpilot FCW are not systems that allow careless or inattentive driving. It is still necessary for the driver to pay close attention to the vehicle’s surroundings and to be ready to re-take control of the gas and the brake at all times.
+
+Many factors can impact the performance of openpilot ACC and openpilot FCW, causing them to be unable to function as intended. These include, but are not limited to:
+
+* Poor visibility (heavy rain, snow, fog, etc.) or weather conditions that may interfere with sensor operation.
+* The road facing camera or radar are obstructed, covered, or damaged by mud, ice, snow, etc.
+* Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
+* The device is mounted incorrectly.
+* Approaching a toll booth, a bridge or a large metal plate.
+* When driving on roads with pedestrians, cyclists, etc...
+* In presence of traffic signs or stop lights, which are not detected by openpilot at this time.
+* When the posted speed limit is below the user selected set speed. openpilot does not detect speed limits at this time.
+* In presence of vehicles in the same lane that are not moving.
+* When abrupt braking maneuvers are required. openpilot is designed to be limited in the amount of deceleration and acceleration that it can produce.
+* When surrounding vehicles perform close cut-ins from neighbor lanes.
+* Driving on hills, narrow, or winding roads.
+* Extremely hot or cold temperatures.
+* Bright light (due to oncoming headlights, direct sunlight, etc.).
+* Interference from other equipment that generates radar waves.
+
+The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. It is the driver's responsibility to be in control of the vehicle at all times.
+
+Limitations of openpilot DM
+------
+
+openpilot DM should not be considered an exact measurement of the alertness of the driver.
+
+Many factors can impact the performance of openpilot DM, causing it to be unable to function as intended. These include, but are not limited to:
+
+* Low light conditions, such as driving at night or in dark tunnels.
+* Bright light (due to oncoming headlights, direct sunlight, etc.).
+* The driver's face is partially or completely outside field of view of the driver facing camera.
+* Right hand driving vehicles.
+* The driver facing camera is obstructed, covered, or damaged.
+
+The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. A driver should not rely on openpilot DM to assess their level of attention.
+
+User Data and comma Account
+------
+
+By default, openpilot uploads the driving data to our servers. You can also access your data by pairing with the comma connect app ([iOS](https://apps.apple.com/us/app/comma-connect/id1456551889), [Android](https://play.google.com/store/apps/details?id=ai.comma.connect&hl=en_US)). We use your data to train better models and improve openpilot for everyone.
+
+openpilot is open source software: the user is free to disable data collection if they wish to do so.
+
+openpilot logs the road facing camera, CAN, GPS, IMU, magnetometer, thermal sensors, crashes, and operating system logs.
+The driver facing camera is only logged if you explicitly opt-in in settings. The microphone is not recorded.
+
+By using openpilot, you agree to [our Privacy Policy](https://my.comma.ai/privacy). You understand that use of this software or its related services will generate certain types of user data, which may be logged and stored at the sole discretion of comma. By accepting this agreement, you grant an irrevocable, perpetual, worldwide right to comma for the use of this data.
+
+Safety and Testing
+----
+
+* openpilot observes ISO26262 guidelines, see [SAFETY.md](SAFETY.md) for more detail.
+* openpilot has software in the loop [tests](.github/workflows/test.yaml) that run on every commit.
+* The safety model code lives in panda and is written in C, see [code rigor](https://github.com/commaai/panda#code-rigor) for more details.
+* panda has software in the loop [safety tests](https://github.com/commaai/panda/tree/master/tests/safety).
+* Internally, we have a hardware in the loop Jenkins test suite that builds and unit tests the various processes.
+* panda has additional hardware in the loop [tests](https://github.com/commaai/panda/blob/master/Jenkinsfile).
+* We run the latest openpilot in a testing closet containing 10 EONs continuously replaying routes.
 
 Testing on PC
 ------
 
-There is rudimentary infrastructure to run a basic simulation and generate a report of openpilot's behavior in different scenarios.
+Check out the tools directory in master: lots of tools you can use to replay driving data, test and develop openpilot from your pc.
 
-```bash
-# Requires working docker
-./run_docker_tests.sh
-```
-
-The results are written to `selfdrive/test/plant/out/index.html`
-
-More extensive testing infrastructure and simulation environments are coming soon.
-
-Adding Car Support
+Community and Contributing
 ------
 
-It should be relatively easy to add support for the Honda CR-V Touring. The brake message is the same. Steering has a slightly different message with a different message id. Sniff CAN while using LKAS to find it.
+openpilot is developed by [comma](https://comma.ai/) and by users like you. We welcome both pull requests and issues on [GitHub](http://github.com/commaai/openpilot). Bug fixes and new car ports are encouraged.
 
-The Honda Accord uses different signaling for the steering and probably requires new hardware.
+You can add support for your car by following guides we have written for [Brand](https://medium.com/@comma_ai/how-to-write-a-car-port-for-openpilot-7ce0785eda84) and [Model](https://medium.com/@comma_ai/openpilot-port-guide-for-toyota-models-e5467f4b5fe6) ports. Generally, a car with adaptive cruise control and lane keep assist is a good candidate. [Join our Discord](https://discord.comma.ai) to discuss car ports: most car makes have a dedicated channel.
 
-Adding other manufacturers besides Honda/Acura is doable but will be more of an undertaking.

 openpilot Safety
 ======
 
-openpilot is an Adaptive Cruise Control and Lane Keeping Assist System. Like
-other ACC and LKAS systems, openpilot requires the driver to be alert and to pay
-attention at all times. We repeat, **driver alertness is necessary, but not
-sufficient, for openpilot to be used safely**.
+openpilot is an Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC) system. 
+Like other ACC and ALC systems, openpilot is a failsafe passive system and it requires the
+driver to be alert and to pay attention at all times.
 
-Even with an attentive driver, we must make further efforts for the system to be
-safe. We have designed openpilot with two other safety considerations.
+In order to enforce driver alertness, openpilot includes a driver monitoring feature
+that alerts the driver when distracted.
 
-1. The vehicle must always be controllable by the driver.
+However, even with an attentive driver, we must make further efforts for the system to be
+safe. We repeat, **driver alertness is necessary, but not sufficient, for openpilot to be
+used safely** and openpilot is provided with no warranty of fitness for any purpose.
+
+openpilot is developed in good faith to be compliant with FMVSS requirements and to follow
+industry standards of safety for Level 2 Driver Assistance Systems. In particular, we observe
+ISO26262 guidelines, including those from [pertinent documents](https://www.nhtsa.gov/sites/nhtsa.dot.gov/files/documents/13498a_812_573_alcsystemreport.pdf)
+released by NHTSA. In addition, we impose strict coding guidelines (like [MISRA C : 2012](https://www.misra.org.uk/MISRAHome/MISRAC2012/tabid/196/Default.aspx))
+on parts of openpilot that are safety relevant. We also perform software-in-the-loop,
+hardware-in-the-loop and in-vehicle tests before each software release.
+
+Following Hazard and Risk Analysis and FMEA, at a very high level, we have designed openpilot
+ensuring two main safety requirements.
+
+1. The driver must always be capable to immediately retake manual control of the vehicle, 
+   by stepping on either pedal or by pressing the cancel button.
 2. The vehicle must not alter its trajectory too quickly for the driver to safely
-   react.
+   react. This means that while the system is engaged, the actuators are constrained
+   to operate within reasonable limits.
 
-To address these, we came up with two safety principles.
+For vehicle specific implementation of the safety concept, refer to `panda/board/safety/`.
 
-1. Enforced disengagements. Step on either pedal or press the cancel button to
-   retake manual control of the car immediately.
-  - These are hard enforced by the board, and soft enforced by the software. The
-    green led on the board signifies if the board is allowing control messages.
-  - Honda CAN uses both a counter and a checksum to ensure integrity and prevent
-    replay of the same message.
-
-2. Actuation limits. While the system is engaged, the actuators are constrained
-   to operate within reasonable limits; the same limits used by the stock system on
-   the Honda.
-  - Without an interceptor, the gas is controlled by the PCM. The PCM limits
-    acceleration to what is reasonable for a cruise control system.  With an
-    interceptor, the gas is clipped to 60% in longcontrol.py
-  - The brake is controlled by the 0x1FA CAN message. This message allows full
-    braking, although the board and the software clip it to 1/4th of the max.
-    This is around .3g of braking.
-  - Steering is controlled by the 0xE4 CAN message. The EPS controller in the
-    car limits the torque to a very small amount, so regardless of the message,
-    the controller cannot jerk the wheel.
+**Extra note**: comma.ai strongly discourages the use of openpilot forks with safety code either missing or
+  not fully meeting the above requirements.

+What is cereal?
+----
+
+cereal is both a messaging spec for robotics systems as well as generic high performance IPC pub sub messaging with a single publisher and multiple subscribers.
+
+Imagine this use case:
+* A sensor process reads gyro measurements directly from an IMU and publishes a sensorEvents packet
+* A calibration process subscribes to the sensorEvents packet to use the IMU
+* A localization process subscribes to the sensorEvents packet to use the IMU also
+
+
+Messaging Spec
+----
+
+You'll find the message types in [log.capnp](log.capnp). It uses [Cap'n proto](https://capnproto.org/capnp-tool.html) and defines one struct called Event.
+
+All Events have a logMonoTime and a valid. Then a big union defines the packet type.
+
+
+Pub Sub Backends
+----
+
+cereal supports two backends, one based on [zmq](https://zeromq.org/), the other called msgq, a custom pub sub based on shared memory that doesn't require the bytes to pass through the kernel.
+
+Example
+---
+```python
+import cereal.messaging as messaging
+
+# in subscriber
+sm = messaging.SubMaster(['sensorEvents'])
+while 1:
+  sm.update()
+  print(sm['sensorEvents'])
+
+# in publisher
+pm = messaging.PubMaster(['sensorEvents'])
+dat = messaging.new_message('sensorEvents', size=1)
+dat.sensorEvents[0] = {"gyro": {"v": [0.1, -0.1, 0.1]}}
+pm.send('sensorEvents', dat)
+```

+[![Build Status](https://dev.azure.com/commaai/default/_apis/build/status/commaai.msgq?branchName=master)](https://dev.azure.com/commaai/default/_build/latest?definitionId=21&branchName=master)
+
+## What is MSGQ?
+MSGQ is a system to pass messages from a single producer to multiple consumers. All the consumers need to be able to receive all the messages. It is designed to be a high performance replacement for ZMQ-like SUB/PUB patterns. It uses a ring buffer in shared memory to efficiently read and write data. Each read requires a copy. Writing can be done without a copy, as long as the size of the data is known in advance.
+
+## Storage
+The storage for the queue consists of an area of metadata, and the actual buffer. The metadata contains:
+
+1. A counter to the number of readers that are active
+2. A pointer to the head of the queue for writing. From now on referred to as *write pointer*
+3. A cycle counter for the writer. This counter is incremented when the writer wraps around
+4. N pointers, pointing to the current read position for all the readers. From now on referred to as *read pointer*
+5. N counters,  counting the number of cycles for all the readers
+6. N booleans, indicating validity for all the readers. From now on referred to as *validity flag*
+
+The counter and the pointer are both 32 bit values, packed into 64 bit so they can be read and written atomically.
+
+The data buffer is a ring buffer. All messages are prefixed by an 8 byte size field, followed by the data. A size of -1 indicates a wrap-around, and means the next message is stored at the beginning of the buffer.
+
+
+## Writing
+Writing involves the following steps:
+
+1. Check if the area that is to be written overlaps with any of the read pointers, mark those readers as invalid by clearing the validity flag.
+2. Write the message
+3. Increase the write pointer by the size of the message
+
+In case there is not enough space at the end of the buffer, a special empty message with a prefix of -1 is written. The cycle counter is incremented by one. In this case step 1 will check there are no read pointers pointing to the remainder of the buffer. Then another write cycle will start with the actual message.
+
+There always needs to be 8 bytes of empty space at the end of the buffer. By doing this there is always space to write the -1.
+
+## Reset reader
+When the reader is lagging too much behind the read pointer becomes invalid and no longer points to the beginning of a valid message. To reset a reader to the current write pointer, the following steps are performed:
+
+1. Set valid flag
+2. Set read cycle counter to that of the writer
+3. Set read pointer to write pointer
+
+## Reading
+Reading involves the following steps:
+
+1. Read the size field at the current read pointer
+2. Read the validity flag
+3. Copy the data out of the buffer
+4. Increase the read pointer by the size of the message
+5. Check the validity flag again
+
+Before starting the copy, the valid flag is checked. This is to prevent a race condition where the size prefix was invalid, and the read could read outside of the buffer. Make sure that step 1 and 2 are not reordered by your compiler or CPU.
+
+If a writer overwrites the data while it's being copied out, the data will be invalid. Therefore the validity flag is also checked after reading it. The order of step 4 and 5 does not matter.
+
+If at steps 2 or 5 the validity flag is not set, the reader is reset. Any data that was already read is discarded. After the reader is reset, the reading starts from the beginning.
+
+If a message with size -1 is encountered, step 3 and 4 are replaced by increasing the cycle counter and setting the read pointer to the beginning of the buffer. After that another read is performed.

+"""ROS has a parameter server, we have files.
+
+The parameter store is a persistent key value store, implemented as a directory with a writer lock.
+On Android, we store params under params_dir = /data/params. The writer lock is a file
+"<params_dir>/.lock" taken using flock(), and data is stored in a directory symlinked to by
+"<params_dir>/d".
+
+Each key, value pair is stored as a file with named <key> with contents <value>, located in
+  <params_dir>/d/<key>
+
+Readers of a single key can just open("<params_dir>/d/<key>") and read the file contents.
+Readers who want a consistent snapshot of multiple keys should take the lock.
+
+Writers should take the lock before modifying anything. Writers should also leave the DB in a
+consistent state after a crash. The implementation below does this by copying all params to a temp
+directory <params_dir>/<tmp>, then atomically symlinking <params_dir>/<d> to <params_dir>/<tmp>
+before deleting the old <params_dir>/<d> directory.
+
+Writers that only modify a single key can simply take the lock, then swap the corresponding value
+file in place without messing with <params_dir>/d.
