+# Contributing
+
+## License
+
+This project is licensed under the terms of the Apache License v2.0 with LLVM
+Exceptions license ([LICENSE.txt](LICENSE.TXT)) to ensure our ability to
+contribute this project to the LLVM test suite project under the same license.
+
+By contributing to this project, you agree to the Apache License v2.0 with LLVM
+Exceptions and copyright terms there in and release your contribution under
+these terms.
+
+## Contribution process
+
+### Development
+
+For any changes not related to DPC++, but rather to LLVM in general, it is
+strongly encouraged that you submit the patch to https://github.com/llvm/llvm-test-suite directly.
+See [LLVM contribution guidelines](https://llvm.org/docs/Contributing.html)
+for more information.
+
+- Create a personal fork of the project on GitHub
+  - For the DPC++ end-to-end test development, use **intel** branch as baseline
+    for your changes.
+- Prepare your patch
+  - follow [LLVM coding standards](https://llvm.org/docs/CodingStandards.html)
+  - [clang-format](https://clang.llvm.org/docs/ClangFormat.html) and
+    [clang-tidy](https://clang.llvm.org/extra/clang-tidy/) tools can be
+    integrated into your workflow to ensure formatting and stylistic
+    compliance of your changes.
+  - use
+
+    ```bash
+    wget https://raw.githubusercontent.com/intel/llvm/sycl/clang/tools/clang-format/git-clang-format
+    python git-clang-format `git merge-base origin/intel HEAD`
+    ```
+
+    to check the format of your current changes against the `origin/intel`
+    branch.
+    - `-f` to also correct unstaged changes
+    - `--diff` to only print the diff without applying
+
+### Testing
+
+- See [SYCL/README.md](SYCL/README.md) for instructions.
+
+### Commit message
+
+- When writing your commit message, please make sure to follow
+  [LLVM developer policies](
+  https://llvm.org/docs/DeveloperPolicy.html#commit-messages) on the subject.
+- For any DPC++-related commit, the `[SYCL]` tag should be present in the
+  commit message title. To a reasonable extent, additional tags can be used
+  to signify the component changed, e.g.: `[LIT]`, `[NFC]`, `[Doc]`.
+
+### Review and acceptance testing
+
+- Create a pull request for your changes following [Creating a pull request
+instructions](https://help.github.com/articles/creating-a-pull-request/).
+  - PR description should follow same rules as commit message. It is used as
+    commit message on the final merge.
+- Changes addressing comments made during code review should be added as a
+  separate commits to the same PR.
+- CI will run checks which are prerequisites for submitting PR:
+  - clang-format-check/build checks that the patch matches coding style
+    (see [clang-format](https://clang.llvm.org/docs/ClangFormat.html));
+  - Jenkins/pre-ci-cuda - runs all related tests on CUDA backend for GPU device
+    on Ubuntu 18.04;
+  - Jenkins/pre-ci-linux - runs all related tests on Ubuntu 18.04 machine with
+  Level_Zero backend (GPU device) and OpenCL backend (CPU, GPU and FPGA
+  emulator devices);
+  - Jenkins/pre-ci-windows - runs all related tests on Windows Server 2019 with
+  Level_Zero backend (GPU device) and OpenCL backend (CPU, GPU and FPGA
+  emulator devices).
+
+The last three checks are done for the latest available nightly build for DPC++
+compiler and runtime from [intel/llvm](https://github.com/intel/llvm). The
+build happens around 18:00 UTC if there are new commits since previous build.
+
+Once the PR is approved and all checks have passed, the pull request is
+ready for merge.
+
+### Merge
+
+Project maintainers merge pull requests by "Squash and merge". PR description
+is used as final commit message.
