 Battery life
 ------------

-I'm currently measuring battery life of v0.5 but previous versions have been able to measure gravity for 
-a 2-3 weeks without issues (Using 900 seconds as interval). 
+The long term battery test has now been completed. Using a 2200 mA battery and sending data every 5 minutes to a local server on my network. The battery lasted 47 days which is excellet battery life. 

-I had a device running with an sleep interval of only 30s with ok wifi connection. The device lasted 
-12 days which i think is excellent considering the short sleep interval. From what I have discovered 
-it's the WIFI connection that has the most impact on the battery life. In a perfect scenario it

+Getting started
+===============
+
+First you need a completed iSpindle hardware, there are several resouces around that topic so it 
+will not be covered in this documentation. Please visit `iSpindel Homepage <https://www.ispindel.de>`_  for 
+more information.
+
+Step 1 - Flash the device
+-------------------------
+
+The first step is to flash the firmware, I recommend using Brewflasher as the easy option. Detailed 
+instructions can be found here :ref:`installation`
+
+Step 2 - Setup WIFI
+-------------------
+
+When the device starts up the first time it will first start an WIFI access point so that the WIFI Settings 
+can be configured. The instructions for that can be found here :ref:`setup_wifi`
+
+Step 3 - Configuration
+----------------------
+
+Once the device can connect to WIFI it will go into `configuration mode` and start a web server for 
+doing the initial configuration. In order to access the device you will need to find its name or ip adress.
+
+It will broadcast a name like gravitymonXXXXXX.local over mDNS. Where the XXXXXX is the unique device id. You can 
+find the name via an mDNS browser, check your router or connect the device to a serial monitor. On windows mDNS 
+might not work so then use the IP address instead. Once connected you will meet a web interface that looks like this.
+
+.. image:: images/index.png
+  :width: 800
+  :alt: Index page
+
+The next step is then to configure the device, most settings should work but there are a few that should be changed.
+
+Configuration - Device Settings - Device Name
+++++++++++++++++++++++++++++++++++++++++++++
+
+Give your device a good name.
+
+Configuration - Device Settings - Gyro Calibration
++++++++++++++++++++++++++++++++++++++++++++++++++
+
+You need to place the device on a flat surface and then press the 
+calibrate button. It will take a few seconds for this to complete and the angle should be close to 90 degress. Without 
+calibration the device will not go into gravity mode.
+
+Configuration - Push Settings
+++++++++++++++++++++++++++++
+Add the endpoints where you want data to be transmitted. All URLs that contain a valid endpoint will receive the data.
+
+Calibration 
+++++++++++
+
+I recommend to use the calibration feature to create a gravity formula. If you have values from a 
+previous calibration then you can add them here, if not follow the calibration guidelines on the iSpindle site.
+
+There are several guides for how to calibrate the device (`iSpindle Calibration <https://www.ispindel.de/docs/Calibration_en.html>`_) 
+
+This will get the data points needed to create the formula, and the datapoints will be stored on the device so you can 
+adjust them when needed.
+
+Step 4 - Completed
+------------------
+
+You are now done and can enjoy the GravityMon software. Check out the :ref:`setting-up-device` section for other configuration options.
+
+If you want to enter the configuration mode place the device flat on a surface and do a reset (or wait until it wakes up). 
+Its recommended to attach the device to power when you have it in `configuration mode` so the battery is not drained. 
+
+**If you have suggestions for more awesome features, head over to the github repository and make a request.**

+* Added possibility to view last 10 errors on device page. 
+* Added possibility to define token parameter used in iSpindle format.
+* Added instructions for how to configure integration with Brewspy
+* Added instructions for how to configure integration with Thingspeak
+* Added option to do a factory reset via API. 
+* Logging the runtime, how long a measurement take (last 10 are stored). This can be 
+  used to check how good the wifi connection is and estimate the lifetime when on battery. 
+  Check the device page in the UI for this information.
+* Refactored code to free up more RAM to make SSL more stable. 
+* Before connecting to an SSL endpoint the device will try to use a new SSL feature 
+  called MFLN (Maximum Fragment Length Negotiation) that allow us to reduce the buffers 
+  from 16k to 2k. This can make a huge difference on a device with only 40k RAM. Not all
