+This is a C++ based repository that uses Qt5 as a primary support and GUI library. This repository is for a password manager application that stores passwords 
+and other highly sensitive information. The data format that passwords are stored is called KDBX which is a mixed binary and XML format that is fully encrypted 
+at rest. This format is unpacked into a series of data structures: Database, Groups, and Entries. Please follow these guidelines when contributing:
+
+## Code Standards
+
+### Required Before Each Commit
+- Run `cmake --build . --target format` before committing any changes to ensure proper code formatting
+- This will run clang-format to ensure all code conforms to the style guide
+- From the checkout directory, also run `./release-tool i18n lupdate` to update translation files
+
+### Development Flow
+- Setup Build Folder: `mkdir build; cd build`
+- Configure: `cmake -G Ninja -DWITH_XC_ALL=ON -DWITH_GUI_TESTS=ON ..`
+- Build: `cmake --build . -- -j $(nproc)`
+- Test: `ctest`
+
+## Repository Structure
+- `docs/topics`: Documentation written in asciidoctor syntax
+- `src/`: Main source code files are under this subdirectory
+- `src/autotype`: Code that emulates a virtual keyboard to type into interfaces
+- `src/browser`: Interface with the KeePassXC Browser Extension using a JSON-based protocol
+- `src/cli`: Command Line Interface code
+- `src/core`: Contains files that define the data model and other shared code structures
+- `src/format`: Code for import/export and reading/writing of KDBX databases
+- `src/fdosecrets`: freedesktop.org Secret Service interface code
+- `src/quickunlock`: Quick unlock interfaces for various platforms
+- `src/sshagent`: SSH Agent interface code to load private keys from the database into ssh-agent
+- `tests/`: Test source code files
+- `tests/gui`: GUI test source code files
+
+## Key Guidelines
+1. Follow C++20 and Qt5 best practices and idiomatic patterns
+2. Maintain existing code structure and organization
+3. Prefer not to edit cryptographic handling code or other sensitive parts of the code base
+4. Write unit tests for new functionality using QTest scaffolding
+5. Suggest changes to the `docs/topics` folder when appropriate
+6. Unless the change is simple, don't actually make edits to .ui files, just suggest the changes needed
