-# Configuration Editor
+# Arduino Static Libraries Configuration Editor
+
+This is a simple application to configure the static libraries for the ESP32 Arduino core.
+It allows the user to select the targets to compile, change the configuration options and compile the libraries.
+
+## Requirements
+  - Python 3.9 or later
+  - The "textual" library (install it using `pip install textual`)
+  - The requirements from esp32-arduino-lib-builder
+
+### WSL
+If you are using WSL, it is recommended to use the Windows Terminal to visualize the application. Otherwise, the application layout and colors might not be displayed correctly.
+The Windows Terminal can be installed from the Microsoft Store.
+
+## Usage

+    -t, --target <target>          Target to be compiled. Choose from: all, esp32, esp32s2, esp32s3, esp32c2, esp32c3, esp32c6, esp32h2
+    --copy, --no-copy              Enable/disable copying the compiled libraries to arduino-esp32. Enabled by default
+    -c, --arduino-path <path>      Path to arduino-esp32 directory. Default: OS dependent
