+# VS Code Dev Container
+This is a docker-based interactive development environment using VS Code and Docker Dev Containers removing the need to install any tools locally*
+
+
+
+## Requirements
+
+- VS Code
+  - [Remote - Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension
+- Docker
+- OpenOCD - For debugging
+
+## Using
+
+### Code editing, and building.
+
+1. Clone InfiniTime and update submodules
+2. Launch VS Code
+3. Open InfiniTime directory, 
+4. Allow VS Code to open folder with devcontainer. 
+
+After this the environment will be built if you do not currently have a container setup, it will install all the necessary tools and extra VSCode extensions. 
+
+In order to build InfiniTime we need to run the initial submodule init and CMake commands.
+
+#### Manually 
+
+ You can use the VS Code terminal to run the CMake commands as outlined in the [build instructions](blob/develop/doc/buildAndProgram.md) 
+
+#### Script
+
+The dev environment comes with some scripts to make this easier, They are located in /opt/.
+
+There are also VS Code tasks provided should you desire to use those. 
+
+The task "update submodules" will update the git submodules
+
+
+
+### Build
+
+You can use the build.sh script located in /opt/
+
+CMake is also configured and controls for the CMake plugin are available in VS Code
+
+
+
+### Debugging
+
+Docker on windows does not support passing USB devices to the underlying WSL2 subsystem, To get around this we use OpenOCD in server mode running on the host.
+
+`openocd -f <yourinterface> -f <nrf52.cfg target file>`
+
+This will launch OpenOCD in server mode and attach it to the MCU. 
+
+The default launch.json file expects OpenOCD to be listening on port 3333, edit if needed
+
+
+## Current Issues
+Currently WSL2 Has some real performance issues with IO on a windows host. Accessing files on the virtualized filesystem is much faster. Using VS Codes "clone in container" feature of the Remote - Containers will get around this. After the container is built you will need to update the submodules and follow the build instructions like normal

-### Code style
-
-Any C++ code PRs should aim to follow the style of existing code in the project. 
-
-Using an autoformatter is heavily recommended, but make sure it's configured properly. 
-
-There's currently preconfigured autoformatter rules for: 
-
-  * CLion (IntelliJ) in .idea/codeStyles/Project.xml
-  
-You can use those to configure your own IDE if it's not already on the list.
-
-#### Linting errors and compiler warnings
-
-Try to avoid any currently enabled warnings and try to reduce the amount of linter errors.
-
-#### Spelling
-
-Make sure you spellcheck your code before commiting it.
-
-#### TODO, FIXME
-
-Check before commiting that you haven't forgotten anything, preferably don't leave these in your commits.
-
-#### Licence headers
-
-You should add your name to the comma-space separated list of contributors if there's a license header.
-
-### License
-
-By contributing you agree to licence your code under the repository's general license (which is currently GPL-v3+).

+# Build and Develop the project using VS Code
+
+The .VS Code folder contains configuration files for developing InfiniTime with VS Code. Effort was made to have these rely on Environment variables instead of hardcoded paths.
+
+## Environment Setup
+
+To support as many setups as possible the VS Code configuration files expect there to be certain environment variables to be set.
+
+ Variable | Description | Example
+----------|-------------|--------
+**ARM_NONE_EABI_TOOLCHAIN_PATH**|path to the toolchain directory|`export ARM_NONE_EABI_TOOLCHAIN_PATH=/opt/gcc-arm-none-eabi-9-2020-q2-update`
+**NRF5_SDK_PATH**|path to the NRF52 SDK|`export NRF5_SDK_PATH=/opt/nRF5_SDK_15.3.0_59ac345`
+
+## VS Code Extensions
+
+We leverage a few VS Code extensions for ease of development.
+
+#### Required Extensions
+
+- [C/C++](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools) - C/C++ IntelliSense, debugging, and code browsing.
+- [CMake Tools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools) - Extended CMake support in Visual Studio Code
+
+#### Optional Extensions
+
+[Cortex-Debug](https://marketplace.visualstudio.com/items?itemName=marus25.cortex-debug) - ARM Cortex-M GDB Debugger support for VS Code
+
+Cortex-Debug is only required for interactive debugging using VS Codes built in GDB support.
+
+
+
+## VS Code/Docker DevContainer
+
+The .devcontainer folder contains the configuration and scripts for using a Docker dev container for building InfiniTime
+
+Using the [Remote-Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension is recommended. It will handle configuring the Docker virtual machine and setting everything up. 
+
+More documentation is available in the [readme in .devcontainer](.devcontainer/readme.md)

+
 ## Write and improve documentation
+
 Documentation might be incomplete, or not clear enough, and it is always possible to improve it with better wording, pictures, photo, video,...
 
 As the documentation is part of the source code, you can submit your improvements to the documentation by submitting a pull request (see below).
+
 ## Fix bugs, add functionalities and improve the code
+
 You want to fix a bug, add a cool new functionality or improve the code? See *How to submit a pull request below*.
+
 ## Spread the word
-The Pinetime is a cool open source project that deserves to be known. Talk about it around you, on social networks, on your blog,... and let people know that we are working on an open-source firmware for a smartwatch!

 # How to submit a pull request ?
 
 ## TL;DR
+
  - Create a branch from develop;
  - Work on a single subject in this branch. Create multiple branches/pulls-requests if you want to work on multiple subjects (bugs, features,...);
  - Test your modifications on the actual hardware;
  - Check the code formatting against our coding conventions and [clang-format](../.clang-format) and [clang-tidy](../.clang-tidy);
  - Clean your code and remove files that are not needed;
- - Write documentation related to your new feature is applicable;
+ - Write documentation related to your new feature if applicable;
- - Create the pull-request and write a great description about it : what does your PR do, why, how,... Add pictures and video if possible;
+ - Create a pull request and write a great description about it : what does your PR do, why, how,... Add pictures and video if possible;

+Your contributions are more than welcome!
 
-If you want to fix a bug, add a functionality or improve the code, you'll first need to create a branch from the **develop** branch (see [this page about the branching model](./branches.md)). This branch is called a feature branch, and you should choose a name that explains what you are working on (ex: "add-doc-about-contributions"). In this branch, **focus on only one topic, bug or feature**. For example, if you created this branch to work on the UI of a specific application, do not commit modifications about the SPI driver. If you want to work on multiple topics, create one branch per topic.

 When your feature branch is ready, **make sure it actually works** and **do not forget to write documentation** about it if it's relevant.
 
-I **strongly discourage to create a PR containing modifications that haven't been tested**. If, for any reason, you cannot test your modifications but want to publish them anyway, **please mention it in the description**. This way, other contributors might be willing to test it and provide feedback about your code.

 Also, before submitting your PR, check the coding style of your code against the **coding conventions** detailed below. This project also provides [clang-format](../.clang-format) and [clang-tidy](../.clang-tidy) configuration files. You can use them to ensure correct formatting of your code.

-Then, you can submit a pull-request for review. Try to **describe your pull request as much as possible**: what did you do in this branch, how does it work, how is it designed, are there any limitations,... This will help the contributors to understand and review your code easily. You can add pictures and video to the description so that contributors will have a quick overview of your work.

 ## Why  all these rules?
-Reviewing pull-requests is a **very time consuming task** for the creator of this project ([JF002](https://github.com/JF002)) and for other contributors who take the time to review them. Every little thing you do to make their lives easier will **increase the chances your PR will be merge quickly**.
 
-When reviewing PR, the author and contributors will first look at the **description**. If it's easy to understand what the PR does, why the modification is needed or interesting and how it's done, a good part of the work is already done : we understand the PR and its context.
+Reviewing pull requests is a **very time consuming task** for the creator of this project ([JF002](https://github.com/JF002)) and for other contributors who take the time to review them. Everything you do to make reviewing easier will **get your PR merged faster**.
 
-Then, reviewing **a few files that were modified for a single purpose** is a lot more easier than to review 30 files modified for many reasons (bug fix, UI improvements, typos in doc,...), even if all these changes make sense. Also, it's possible that we agree on some modification but not on some other, and we won't be able to merge the PR because of the changes that are not accepted.

-We do our best to keep the code as consistent as possible, and that means we pay attention to the **formatting** of the code. If the code formatting is not consistent with our code base, we'll ask you to review it, which will take more time.

 # Coding convention
-## Language
-The language of this project is **C++**, and all new code must be written in C++. (Modern) C++ provides a lot of useful tools and functionalities that are beneficial for embedded software development like `constexpr`, `template` and anything that provides zero-cost abstraction.  
 
-It's OK to include C code if this code comes from another library like FreeRTOS, NimBLE, LVGL or the NRF-SDK.

 The most important rule to follow is to try to keep the code as easy to read and maintain as possible.
 
+Using an autoformatter is highly recommended, but make sure it's configured properly.
+
+There are preconfigured autoformatter rules for:

+  * CLion (IntelliJ) in .idea/codeStyles/Project.xml
+
+If there are no preconfigured rules for your IDE, you can use one of the existing ones to configure your IDE.

  - **Indentation** : 2 spaces, no tabulation
  - **Opening brace** at the end of the line
  - **Naming** : Choose self-describing variable name

+- Align objects all the way to the edge or corner
+- Buttons should generally be at least 50px high
+- Buttons should generally be on the bottom edge
+- Make interactable objects **big**
+- Recommendations for inner padding, aka distance between buttons:
+	- When aligning 4 objects: 4px, e.g. Settings
+	- When aligning 3 objects: 6px, e.g. App list
+	- When aligning 2 objects: 10px, e.g. Quick settings
+- When using a page indicator, leave 8px for it on the right side
+	- It is acceptable to leave 8px on the left side as well to center the content
+- Top bar takes at least 20px + padding
+	- Top bar right icons move 8px to the left when using a page indicator
