-# pico-webserver
+# pico-webserver
+
+Webserver example that came with TinyUSB slightly modified to run on a Raspberry Pi Pico.
+Lets the Pico pretend to be a USB Ethernet device. Runs a webinterface at http://192.168.7.1/
+
+## Build dependencies
+
+On Debian:
+
+```
+sudo apt install git build-essential cmake gcc-arm-none-eabi
+```
+
+Your Linux distribution does need to provide a recent CMake (3.13+).
+If not, compile [CMake from source](https://cmake.org/download/#latest) first.
+
+## Build instructions
+
+```
+git clone --depth 1 https://github.com/maxnet/pico-webserver
+cd pico-webserver
+git submodule update --init --depth 1
+mkdir -p build
+cd build
+cmake ..
+make
+```
+
+Copy the resulting pico_webserver.uf2 file to the Pico mass storage device manually.
+Webserver will be available at http://192.168.7.1/
+
+Content it is serving is in /fs
+If you change any files there, run ./regen-fsdata.sh
+
+By default it shows a webpage that led you toggle the Pico's led, and allows you to switch to BOOTSEL mode.
