+# Instructions for making a turn-key image
+
+## Flash Raspbian Stretch Lite
+
+Starting from version [Raspbian Stretch Lite](https://www.raspberrypi.org/downloads/raspbian/) version 2017-11-29.
+
+```
+sudo dd bs=4M if=2017-11-29-raspbian-stretch-lite.img of=/dev/mmcblk0 conv=fsync status=progress
+```
+
+Change `/dev/mmcblk0` to whatever your SD card is (find it using `fdisk -l`).
+
+After flashing, for the first time use, just plug in ethernet and you can SSH into the Pi. To activate SSH on boot just do
+
+```
+touch /media/YOURUSER/boot/ssh
+```
+
+## Add libraries onto the Pi
+
+```
+sudo apt-get update
+sudo apt-get dist-upgrade -y
+sudo apt-get install -y dnsmasq hostapd vim python3-flask git
+```
+
+## Install node 
+
+```
+wget https://nodejs.org/dist/v8.9.4/node-v8.9.4-linux-armv6l.tar.xz
+sudo mkdir /usr/lib/nodejs
+sudo tar -xJvf node-v8.9.4-linux-armv6l.tar.xz -C /usr/lib/nodejs 
+rm -rf node-v8.9.4-linux-armv6l.tar.xz
+sudo mv /usr/lib/nodejs/node-v8.9.4-linux-armv6l /usr/lib/nodejs/node-v8.9.4
+echo 'export NODEJS_HOME=/usr/lib/nodejs/node-v8.9.4' >> ~/.profile
+echo 'export PATH=$NODEJS_HOME/bin:$PATH' >> ~/.profile
+source ~/.profile
+```
+
+## Install Go
+
+```
+wget https://dl.google.com/go/go1.10.linux-armv6l.tar.gz
+sudo tar -C /usr/local -xzf go*gz
+rm go*gz
+echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >>  ~/.profile
+echo 'export GOPATH=$HOME/go' >>  ~/.profile
+source ~/.profile
+```
+
+# Install base station
+
+```
+git clone https://github.com/schollz/raspberry-pi-turnkey.git
+```
+
+# Install Hostapd
+
+```
+sudo systemctl stop dnsmasq && sudo systemctl stop hostapd
+
+echo 'interface wlan0
+static ip_address=192.168.4.1/24' | sudo tee --append /etc/dhcpcd.conf
+sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig

+sudo systemctl daemon-reload
+sudo systemctl restart dhcpcd

+echo 'interface=wlan0
+dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h' | sudo tee --append /etc/dnsmasq.conf

+```
+
+Add to cron
+
+```
+@reboot cd /home/pi/raspberry-pi-turnkey && /usr/bin/sudo /usr/bin/python3 startup.py
