-# Instructions for OpenAI Codex
-
-This file provides guidelines for OpenAI Codex to ensure code quality and consistency within this project.
-
-## General Instructions
-
-1. **Follow Existing Code Style**: Adhere to the style already present in the repository.
-2. **Use TypeScript**: All new code must be written in TypeScript.
-3. **Meaningful Names**: Use descriptive names for variables and functions.
-4. **Comments**: Comment complex logic to explain its purpose.
-
-## Testing
-
-1. **Testing Framework**: Use Mocha and Chai for tests.
-2. **Run Tests**: Compile the project then run `npm test` to execute all tests.
-3. **Test Files**: Maintain and extend existing test files when adding new functionality.
-
-## Commands
-
-1. **Build**: `npm run build`
-2. **Run All Tests**: `npm test`
-3. **Watch Tests**: `npm run test_watch`
-4. **Coverage**: `npm run cover`
-5. **Lint**: `npx tslint -c tslint.json -p tsconfig.json`
-
-## Pull Request Guidelines
-
-1. **Description**: Provide a clear description of the changes.
-2. **Related Issues**: Reference any related issues.
-3. **Tests**: Ensure all tests pass before submission.
-4. **Single Concern**: Keep pull requests focused on a single concern.
-
-## Important
-
-After making any changes, Codex MUST run `npm run build` and `npm test` to confirm that the build and tests pass.

+# Development Plan
+
+This document outlines possible improvements and future developments for the `TSDataStructure` project.
+
+## Code Quality and Tooling
+
+- **Adopt ESLint**: Replace the deprecated TSLint configuration with ESLint to keep the linting ecosystem up to date.
+- **Upgrade Dependencies**: Review and update dependencies regularly to keep up with security fixes and improvements.
+- **TypeScript Strict Mode**: Consider enabling `strictNullChecks` and other strict compiler options for safer type checking.
+
+## Testing and CI
+
+- **Increase Test Coverage**: Add more unit tests covering edge cases and error conditions for all data structures.
+- **Continuous Integration**: Configure a modern CI workflow (e.g., GitHub Actions) to automatically run build and tests on each commit.
+- **Coverage Reporting**: Switch from `istanbul` to `nyc` or a modern coverage tool and publish coverage reports.
+
+## New Data Structures
+
+- **Graph**: Implement a basic graph structure with common algorithms such as BFS, DFS, and shortest path algorithms.
+- **PriorityQueue**: Provide a priority queue implementation for efficient task scheduling.
+- **Balanced Trees**: Add self-balancing tree variants (e.g., AVL or Red-Black trees) for more efficient search and insert operations.
+
+## Documentation
+
+- **API Examples**: Expand the README with practical examples demonstrating each data structure in real-world scenarios.
+- **Contribution Guide**: Provide a `CONTRIBUTING.md` describing how to set up the project, run tests, and submit pull requests.
+- **Changelog**: Maintain a `CHANGELOG.md` to track notable changes between releases.
+
+## Packaging and Distribution
+
+- **Publish to npm**: Ensure the package is published to npm with clear versioning and release notes.
+- **Type Declarations**: Generate `.d.ts` files to support TypeScript consumers directly.
+
+## Future Enhancements
+
+- **Performance Benchmarks**: Add benchmarks to evaluate and optimize the performance of the data structures.
+- **Browser Support**: Provide build targets that work in browser environments, possibly using bundlers like Rollup or Webpack.
+- **Typed Iterators**: Implement iterator interfaces for data structures to integrate seamlessly with ES6 iteration protocols.
