-Path reporting for borrowed goods
+## _Path Reporting for Borrowed Goods_
+
+## Installation
+### Necessary Software
+- [Golang][go]
+- [Arduino IDE][ard] and [ESP plugin][esp]
+
+### Necessary Hardware
+- Computer (I used a [Raspberry Pi Zero 2 W][vilros])
+- [ESP8266][espbuy]
+- [uBlox 6m GPS module][gps]
+- External Power Supply
+
+## Setup
+### Serverside
+Compile the recipient Golang program on the computer with
+```sh
+go build gps.go
+```
+### Nodeside
+Open the sketch and user the Arduino IDE to upload to the ESP module
+Connect the GPS module; pinout is given in Arduino sketch, must check against pinout image
+
+## Running
+### Serverside
+Run the recipient with
+```sh
+./gps &
+```
+When the path is received, it will be stored in a file named with the received date. It can be viewed with
+```sh
+cat YYYYMMDD.path
+```
+### Nodeside
+Compile and download the sketch to the ESP
+
+## Usage
+Connect the ESP and GPS to the external battery. Once the GPS warms up, it will get a location reading every 2 seconds. Power does not need to be continuously supplied, as the location is written to the EEPROM. To get the location data, reset/power cycle ESP.
+
+## TODO
+- A whole lot
+- Golang write to file
+- Golang plotting
+- ESP connectivity
+- ESP write to EEPROM
