+Configuration
+===============================
+Configuration can be done in several ways. The priority order is as follows: configuration files are overridden by environment variables, which in turn can be overridden by command-line arguments. If you go through the wizard, the choices you make there will take the highest precedence.
+
+Wizard
+-------------------------
+To start the wizard, simply run eim without any parameters. The wizard will guide you through the installation process. Generally, you can use the arrow keys to navigate between options, the spacebar to select options, and the Enter key to confirm your selections.
+
+As the final step, the wizard will allow you to save your installation choices as a configuration file. This file can be shared or reused in future installations to replicate the same setup.
+
+
+Command line arguments
+---------------------------------
+The easiest way to see all possible command-line arguments is to run eim --help, which will display the following help screen:
+
+.. figure:: ../_static/help.png
+
+Config File
+---------------------------------
+The installer can use a TOML configuration file. By default, it looks for this file at ./config/default.toml, but you can specify a different path using the `--config` command-line argument.
+
+Here is an example of what a configuration file might look like:
+.. code::
+
+    path = "/tmp/esp-new/"
+    idf_path = "/tmp/esp-new/v5.3/esp-idf"
+    tool_download_folder_name = "dist"
+    tool_install_folder_name = "tools"
+    target = ["all"]
+    idf_versions = ["v5.3"]
+    tools_json_file = "tools/tools.json"
+    idf_tools_path = "./tools/idf_tools.py"
+    mirror = "https://github.com"
+    idf_mirror = "https://github.com"
+
+Env variables
+---------------------------------
+You can override any of the configuration settings by exporting environment variables prefixed with `ESP_`. For example, to override the `target` setting, you would use `ESP_TARGET`.

-Installation
+Installation of IDF
+===============================
+Installing the ESP-IDF using EIM is straightforward. Simply open your preferred shell (we recommend PowerShell for Windows users) and run EIM, providing your installation preferences using any of the configuration <configuration> methods you choose. If you haven't provided all the necessary options, an interactive wizard will guide you through the remaining steps.
+
+After Installation 
 ===============================
-Installation process goes here.
 
 Windows
 -------------------------
-Windows process goes here.
-
+On Windows, the installer creates an icon on your desktop labeled IDF_PowerShell. Clicking this icon will launch PowerShell with the environment set up, allowing you to start using ESP-IDF immediately. If you've installed multiple versions of ESP-IDF, you will have multiple icons, one for each version.
 
-macOS
+macOS & Linux
 ---------------------------------
-macOS process goes here.
+In the installation directory you selected, there will be a .sh script that, when sourced, activates the ESP-IDF environment in your current shell. It's important to note that this script should be sourced, not executed directly. If you've installed multiple versions of ESP-IDF, there will be a separate script for each version.
 
-Linux
----------------------------------
-Linux specific documentation here.
+.. note::
+
+    The script should be really sourced and not executed
