 Install Arduino IDE if you don't already have it, and upgrade to something recent if you're below version 1.7 - http://arduino.cc
+  *Go to Preferences in the Arduino app, and enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
   * In Boards Manager, add ESP8266 Board support

+  * In the page that comes up, click "Bring Your Own Thing" The page that brings up will have your MQTT username/password/client ID information
 Install the following libraries:

-Modify BME280 library
+For each of these four libraries, click on the "Clone or download" button, and download the ZIP file (more complicated things can be done if you're Git savvy, but plain old zip download is fine here...) From there, you should be able to install the libraries using Sketch->Include Library-> Add .ZIP Library (you may need to strip the -master from the .zip files filename)
+Modify BME280 library:
   * on OS X, navigate using the finder or otherwise cd ~/Documents/Arduino/libraries/Adafruit_BME280_Library-master/
-    * On Windows & Linux the files will be somewhere similar.
+    * On Windows & Linux the files will be somewhere similar - you can find your base directory via Preferences, and from there get to the libraries folder
-  * edit Adafruit_BME280.h using your favorite editor, and change #define BME280_ADDRESS from 0x77 to 0x76
+  * edit Adafruit_BME280.h using your favorite editor, and change #define BME280_ADDRESS from 0x77 to 0x76- it should be around line 34 or so.
+  * I originally had some stuff about modifying the library further, but it didn't work. Just do this, and remember to change it back if you ever get an official Adafruit BME280 breakout board.

 ==Hardware Construction==
+  * First things first- TEST THE VOLTAGE REGULATOR BOARD. Unfortunately, these boards are capable of failing short (i.e. the input voltage can end up at the output, which will fry your ESP8266!!). Hook up your power source to the Vin of the regulator board. Using a voltmeter, check the voltage at Vout. It should be about 3.3V, give or take .1 V. If it is more than this, get another board and throw this one away!
   * On the programming board, wire an SPST or SPDT switch between GPIO and GND
   * If you plan on re-using the boards for something else in the future, solder in header pins on the other boards. If you're building this as a fixed-in-place design, you'll want to just solder wires to the boards. Theoretically, the person that designed this de-solders the pins from the ESP8266 board, but that seems foolhardy to me (makes it MUCH more difficult to reprogram...)
