+# Contributing
+
+Thank you for investing your time in contributing to our project! We welcome feedback, bug reports, and pull requests!
+
+## New contributor guide
+
+Ours develop branch is `main` not `master` (`master` used to be the develop branch for v1.x).
+
+The reason we didn't delete the `master` branch is that there are still users whose workflows point to the `master` branch.
+
+For pull requests, please stick to the following guidelines
+
+* Add tests for any new features and bug fixes.
+* Put a reasonable amount of comments into the code.
+* Fork cpp-linter-action on your GitHub user account, do your changes there and then create a PR against `main` branch of cpp-linter-action repository.
+* Separate unrelated changes into multiple pull requests.
+
+If you wish to contribute to the python source package used by this action, then that has moved to it's own repository named [cpp-linter](https://github.com/cpp-linter/cpp-linter) as of v2 of this action.
+
+Please note that by contributing any code or documentation to this repository (by raising pull requests, or otherwise) you explicitly agree to the [License Agreement](LICENSE).

 A Github Action for linting C/C++ code integrating clang-tidy and clang-format to collect feedback provided in the form of thread comments and/or annotations.
 
+## What's New
+
+v2
+
+* Change action from using docker to composite steps
+  * improve workflow runs times from 1m 24s (currently) to 6-20s.
+  * better support for the database input option (which is currently broken with the docker env).
+  * better support cross-compilation
+  * better support 3rd party libraries
+* Includes many issues and enhancements. See [#87](https://github.com/cpp-linter/cpp-linter-action/issues/87) for details.
+
+Refer [here](https://github.com/cpp-linter/cpp-linter-action/tree/v1) for previous versions.

 ## Usage
 
-Create a new GitHub Actions workflow in your project, e.g. at [.github/workflows/cpp-linter.yml](https://github.com/cpp-linter/cpp-linter-action/blob/master/.github/workflows/cpp-linter.yml)

 The content of the file should be in the following format.

 ### Outputs
 
 This action creates 1 output variable named `checks-failed`. Even if the linting checks fail for source files this action will still pass, but users' CI workflows can use this action's output to exit the workflow early if that is desired.
 
-## Running without the docker container
-
-Some Continuous Integration environments require access to non-default compilers
-and/or non-standard libraries. To do this properly, the docker container should
-not be used due to it's isolated file system. Instead, you should use this action's
-python source code as an installed python package (see below).
-
-### Using the python source code
-
-This action was originally designed to only be used on a runner with the Ubuntu
-Operating System. However, this action's source code (essentially a python package)
-can be used on any runner using the Windows, Ubuntu, or possibly even MacOS (untested)
-virtual environments.
-
-Note, some runners already ship with clang-format and/or clang-tidy. As of this writing, the following versions of clang-format and clang-tidy are already available:
-
-- `ubuntu-latest` ships with v10, v11, and v12. [More details](https://github.com/actions/virtual-environments/blob/ubuntu20/20220508.1/images/linux/Ubuntu2004-Readme.md).
-- `windows-latest` ships with v13. [More details](https://github.com/actions/virtual-environments/blob/win22/20220511.2/images/win/Windows2022-Readme.md).
-- `macos-latest` ships with v13. [More details](https://github.com/actions/virtual-environments/blob/main/images/macos/macos-11-Readme.md).

-This example makes use of another action
-([KyleMayes/install-llvm-action](https://github.com/KyleMayes/install-llvm-action))
-to install a certain version of clang-tidy and clang-format.
