+[pip](https://pip.pypa.io/) is the default package manager for Python.
+It is used to install, update and remove Python packages from the Python Package Index (PyPI) and
+other package repositories.
+
+## Usage
+
+### Installing Packages
+
+A package can be installed by replacing `<package>` with its name.
+
+```sh
+pip install <package>
+```
+
+It is generally recommended to install packages inside a
+[virtual environment](/wiki/programming_language/python.md#using-virtual-environments).
+Alternatively, project-based package managers such as [uv](/wiki/programming_language/python/uv.md)
+can be used.
+
+On some Linux distributions global installation may require the
+`--break-system-packages` flag.
+
+```sh
+pip install --break-system-packages <package>
+```
+
+This option should only be used if the package cannot be installed using the
+[system package manager](/wiki/linux/package_manager.md#list-of-package-managers) or inside a
+virtual environment.
+
+### Removing Packages
+
+Installed packages can be removed by replacing `<package>` with the package
+name.
+
+```sh
+pip uninstall <package>
+```
+
+### Creating a `requirements.txt` File
+
+To automatically create a `requirements.txt` file for the current project,
+navigate to the project directory and run `pipreqs`.
+
+```sh
+pipreqs .
+```
