+# Picokeyboard
+
+## About
+
+This project turns a Raspberry Pi Pico W into a web-based USB HID keyboard 
+device. Users can access a webpage served over HTTP to enter keyboard input
+onto the host device of the Raspberry Pi Pico W. Input keys can be entered
+through a keyboard on the client device or by pressing on the keys on the
+graphical interface served on the webpage.

+
+## Setup
+
+Flash the [webkeyboard.uf2](raw/branch/main/build/webkeyboard.uf2) file onto
+the Raspberry Pi Pico W and connect the Raspberry Pi Pico W with a micro USB
+cable to the host computer or other device.
+
+On initial boot, the Raspberry Pi Pico W will enter Access Point mode with
+SSID "picokb" and password "password". Connect to this network with another
+device and open a browser window to [http://picokb](http://picokb).
+Go to the "Configure W-Fi" page and enter the SSID and password to the
+network that you would like the Raspberry Pi Pico W to connect. Optionally,
+also enter a hostname for the device and static IP information. Hit the "Save"
+button to save the network information to device flash.
+
+Browse back to the main UI page at [http://picokb](http://picokb) and press
+"Reboot". The device should automatically connect to the network with the
+saved information. You can then connect to the device using a web browser
+at the device's assigned IP or hostname by accessing http://IP_ADDRESS or
+http://HOSTNAME
+
+If the fails to connect to the saved Wi-Fi network, it will once again enter
+Access Point mode, and you can connect to the device directly to modify the
+network information.
+
+Alternatively, you can use the device directly in Access Point mode by
+accessing the device at [http://picokb](http://picokb). The program is
+set to reboot automatically to try to reconnect to the nextwork after 10
+minutes of inactivity if no keyboard input is received during that time.
