+# Ultralytics YOLO 🚀, AGPL-3.0 license
+# Publish pip package to PyPI https://pypi.org/project/ultralytics/ and Docs to https://docs.ultralytics.com
+#
+# Overview:
+# This `pyproject.toml` file manages the build, packaging, and distribution of the `thop` library. 
+# It defines essential project metadata, dependencies, and settings used to develop and deploy the library.
+# 
+# Key Sections:
+# - `[build-system]`: Specifies the build requirements and backend (e.g., setuptools, wheel).
+# - `[project]`: Includes details like name, version, description, authors, dependencies, and more.
+# - `[tool.setuptools.dynamic]`: Configures dynamic versioning for the project.
+# - `[tool.setuptools]`: Configures settings specific to the `setuptools` build backend.
+# 
+# Installation:
+# The `thop` library can be installed using the command: `pip install thop`
+# For development purposes, you can install the package in editable mode with: `pip install -e .`
+# This approach allows for real-time code modifications without the need for re-installation.
+# 
+# Documentation:
+# For comprehensive documentation and usage instructions, visit: https://github.com/ultralytics/thop
