+# Fork of YOLOv5
+
+## About the package
+
+\# TODO
+
+## Package management
+
+### Makefile
+
+Poetry `~1.2` is required to run the Makefile.
+
+Install the environment:
+
+```bash
+make env
+```
+
+Build the source and wheel distribution:
+
+```bash
+make dist
+```
+
+Build and release the package to the private PyPI (requires to setup Poetry auth), and tag this commit:
+```bash
+make release
+```
+
+Remove all temporary files (cached Python code)
+```bash
+make clean
+```
+
+### Poetry
+
+This package is using Poetry. Here are some usefull commands.
+
+```bash
+# Install current package environment
+poetry install
+
+# Install current package environment with dev dependencies
+poetry install --with dev
+
+# Run a command inside the virtualenv
+poetry run my_command
+
+# Enter the virtualenv (exit with exit command or <CTRL+D>)
+poetry shell
+
+# Update dependances
+poetry lock
+
+# Refresh lock file without looking for updated packages
+poetry lock --no-update
+```
