+# OTA Wifi Configuration
+
+OTA Wifi Configuration is a program to headlessly configure a Raspberry Pi's WiFi
+connection using using any other WiFi-enabled device (much like the way
+a Chromecast or similar device can be configured).
+
+### OTA Wifi Configuration has been tested with
+
+-   Raspberry Pi 4b Running Raspberry Pi Os Buster Lite
+
+### OTA Wifi Configuration should work with
+
+-   Any rasberry Pi running Raspberry Pi Os Buster or Bullseye
+
+## Installation Instructions:
+
+-   Navigate to the directory where you downloaded or cloned OTA Wifi Configuration
+
+-   Run: `sudo python3 setup.py`, **Must be run with sudo or as root**
+
+-   This script will install all necessary prerequisites and copy all necessary
+    config and library files, then reboot.
+-   Wait for it to finish booting then go back to the directory that you cloned or downloaded OTA Wifi Configuration and run `sudo python3 app.py`
+-   It should
+    present itself in _Configuration Mode_ as a WiFi access point with the
+    name **Device [xxxx]**. The Xs being replaced with the last four digits of your raspberry pi's serial number.
+
+## Usage:
+
+-   Connect to the **Device [xxxx]** access point using any other WiFi enabled
+    device.
+
+-   Make an http request to [**192.168.50.10**] or [**setup.com**] on port 5000
+
+## Api:
+
+### **/connected** - Attempts to set the wifi on the device. It will set the credentials then restart the device. Will return a 200 status code if succeeded.
+
+-   **Params** - The params must be passed in as JSON data. Mimetype must indicate JSON (application/json).
+    -   **SSID** - String - The ssid of the wifi you wish to connect to.
+    -   **wifi_key** - String - The wpa key of the wifi you wish to connect to.
+-   **Returns** - **{"status": "success", "status_code": 200}** if succeeded or **{"status": "failed", "status_code": 500}** if failed
+
+### **/save_credentials** - will return a 200 status code if succeeded.
+
+-   **Params** - None
+-   **Returns** - {"status_code": 200}
+
+## Resetting the device:
+
+### You can reset the device by running setup.py again as root or with sudo.
+
+## Stopping access point
+
+## You can disable the access point by running disable_access_point.py as root or with sudo.
