+# Standardize Python project configuration
+
+This part of the documentation describes how to standardize Python project configuration in Plone.
+It does not cover Volto or any other JavaScript-based project, which has its own ecosystem.
+
+Plone consists of hundreds of projects.
+To lessen the effort of configuring a new project in the Plone GitHub organization, and to keep these projects current with latest configuration practices, the Plone community agreed upon a trusted set of configuration items.
+The Plone community manages these configuration items using the [`meta`](https://github.com/plone/meta) project.
+
+You can follow these practices in your own projects, or suggest new or alternative configuration items through the `meta` repository, sharing them with the rest of the Plone community.
+
+
+## `meta` basic usage
+
+`meta` has a rich set of features.
+This section describes the most common use cases.
+
+```{seealso}
+See a description of all of [`meta`'s features](https://github.com/plone/meta/blob/main/config/README.md#quick-start).
+```
+
+
+### Setup
+
+Clone `meta` to any machine, then change your current working directory into `meta/config`, create a Python virtual environment, activate it, and install `meta`'s requirements.
+
+```shell
+git clone https://github.com/plone/meta.git
+cd meta/config
+python3 -m venv venv
+. venv/bin/activate
+pip install -r requirements.txt
+```
+
+
+### `config-package.py` script
+
+The {file}`config-package.py` Python script from `meta` creates or overwrites configuration files for your project.
+See a current list of [configuration files](https://github.com/plone/meta/blob/main/config/README.md#configuration-files) that it will create or overwrite.
+
+This script has several [command line options](https://github.com/plone/meta/blob/main/config/README.md#cli-arguments) that you can use to override the default options.
+
+When you run this script, it automatically goes through the following steps.
+
+1.  It creates a new git branch from the current branch in your project.
+1.  If the file {file}`.meta.toml` is not present in the project, then it creates this and the other new configuration files from `meta`'s Jinja2 templates.
+    Otherwise, it reads the file {file}`.meta.toml` for regenerating the configuration files.
+1.  It writes the configuration files.
+1.  It creates a change log entry.
+1.  By default, it commits changes.
+1.  It optionally adds packages, pushes commits, or runs tox from the configuration files. 
+
+```{tip}
+If you prefer to name the new git branch instead of letting the script name it using its default naming scheme, then either create a new branch `my-new-branch`, switch to it, and use the `--branch current` option, or do all that in one step with the `--branch my-new-branch` option.
+```
+
+```{tip}
+If you prefer to review changes before committing them, then use the `--no-commit` option.
+```
+
+For help for the script, use the following command.
+
+```shell
+python config-package.py --help
+```
+
+
+### Generate configuration files
+
+Now you can run the Python script {file}`config-package.py` to generate configuration files from Jinja2 template files to manage your project.
+
+```shell
+python config-package.py [OPTIONS] PATH/TO/PACKAGE
+```
+
+
+### Manage configuration files
+
+For each of the configuration files, you should edit its [corresponding stanza](https://github.com/plone/meta/blob/main/config/README.md#applying-a-customized-configuration) in the file {file}`.meta.toml`.
+
+```{warning}
+Do not directly edit the configuration files that `meta` manages.
+Anytime someone runs the Python script {file}`config-package.py`, any changes made in these files will get clobbered.
+```
+
+Then run the Python script {file}`config-package.py` to regenerate configuration files from your project's {file}`.meta.toml`.
+
+```shell
+python config-package.py [OPTIONS] PATH/TO/PACKAGE
+```
