+# Properties
+
+Easily control your environment properties.
+
+## Purpose
+
+Many projects use environment property files and need to manually swap these properties when testing in different environments. This project aims to facilitate the management of these environment properties.
+
+## Proposal
+
+Inspired a bit by Git, I thought of the following commands: [install](#install), [save](#save), [checkout](#checkout), [list](#list), and [remove](#remove).
+
+### Install
+
+First, you need to install the management in the project folder:
+
+```bash
+$ properties install
+```
+
+This will create a configuration file and a folder to store the environments.
+
+### Save
+
+With this command, you can save an environment with an associated tag, allowing you to later checkout in it.
+
+```bash
+$ properties save <tag>
+```
+
+### Checkout
+
+This command allows you to checkout in a saved environment.
+
+```bash
+$ properties checkout <tag>
+```
+
+### List
+
+This command allows you to list the saved environments.
+
+```bash
+$ properties list
+```
+
+If you specify a tag, the properties associated with it will be displayed.
+
+```bash
+$ properties list <tag>
+```
+
+### Remove
+
+This command allows you to remove a saved environment.
+
+```bash
+$ properties remove <tag>
+```
