+## [unreleased]
+
+### Added
+- Added `.clang-tidy` that implements basic `Checks` like `cppcoreguidelines`, `modernize` and `readability` etc along with basic naming-conventions for Classes, Functions and Variables.
+- Added `CHANGELOG.md` to document all notable changes in a particular commit or release.
+- Added `.pre-commit-config.yaml` to automate formatting, linting, analysing, spell-correction, and other pesky tasks & checklist (install using `pre-commit install`).
+
+### Changed
+- Customized `.clang-format` for C++, away from pure LLVM coding-style. See [ClangFormatStyleOptions](https://clang.llvm.org/docs/ClangFormatStyleOptions.html) for more on what each does. tl;dr, it's just better? alignment and four-space tab. pro-tip: use empty line to separate two blocks of declarations.
