+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# Simple Console Initializer
+The component provides a simple api's to initialize and start the esp console.
+It also provides an api to register an user provided command.
+
+## API
+
+### Steps to enable console in an example code:
+1. Add this component to your project using ```idf.py add-dependency``` command.
+2. In the main file of the example, add the following line:
+    ```c
+    #include "console_simple_init.h"
+    ```
+3. Ensure NVS flash is initialized and default event loop is created in your app_main():
+    ```c
+    ESP_ERROR_CHECK(esp_event_loop_create_default());
+    esp_err_t ret = nvs_flash_init();   //Initialize NVS
+    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
+        ESP_ERROR_CHECK(nvs_flash_erase());
+        ret = nvs_flash_init();
+    }
+    ESP_ERROR_CHECK(ret);
+    ```
+4. In your app_main() function, add the following line as the last line:
+    ```c
+    ESP_ERROR_CHECK(console_cmd_init());     // Initialize console
+
+    // Define the function prototype for do_user_cmd
+    // It's a function that takes an integer (argc) and a pointer to a pointer to char (argv)
+    int do_user_cmd(int argc, char **argv);
+
+    // Register the do_user_cmd function as a command callback function for "user" command
+    // This allows you to execute the do_user_cmd function when the "user" command is invoked
+    ESP_ERROR_CHECK(console_cmd_user_register("user", do_user_cmd));
+
+
+    ESP_ERROR_CHECK(console_cmd_start());    // Start console
+    ```
