+Software Setup
+==============
+
+Once you've built or otherwise obtained a PiFinder, here's how to setup a fresh SD card to run it.  You can do this completely headless (no monitor / keyboard) if desired.
+
+General Pi Setup
+----------------
+
+
+* Create Image:  I'd strongly recommend using the Rapsberry Pi imager.  It's available for most platforms and lets you easily setup wifi and SSH for your new image.
+
+  * Select the 64-Bit version of Pi OS (**Legacy**) Lite (No Desktop Environment)
+
+    * **Make sure you select the Legacy Bullseye option here**
+
+  * Setup SSH / Wifi / User and Host name using the gear icon.  Below is a screengrab showing the suggested settings.
+
+    * **The username must be** ``pifinder``
+    * The host name, password, network settings and locale should be customized for your needs.

+
+
+
+* Once the image is burned to an SD card, insert it into the PiFinder and power it up.   It will probably take a few minutes to boot the first time.
+* SSH into the Pifinder using ``[email protected]`` and the password you  setup.
+* Update all packages.  This is not strictly required, but is a good practice.
+
+  * ``sudo apt update``
+  * ``sudo apt upgrade``
+
+    * Enable SPI / I2C.  The screen and IMU use these to communicate.  
+    * run ``sudo raspi-config``
+    * Select 3 - Interface Options
+    * Then I4 - SPI  and choose Enable
+    * Then I5 - I2C  and choose Enable
+
+PiFinder Software Install
+-------------------------
+
+Great!  You have a nice fresh install of Raspberry Pi OS ready to go.  The rest of the setup is completed by running the ``pifinder_setup.sh`` script in this repo.  Here's the command to download and run the script in one step:
+
+ ``wget -O - https://raw.githubusercontent.com/brickbots/PiFinder/release/pifinder_setup.sh | bash``
+
+The script:
+
+
+* Clone this repo
+* Install the needed packages/dependencies
+* Download some required astronomy data files
+* Setup Wifi access point capabilities
+* Create a samba share for pulling images, and observations logs and adding observing lists
+* Finally, setup the PiFinder service to start on reboot.
+
+Once the script is done, reboot the PiFinder:
+``sudo shutdown -r now``
+
+It will take up to two minutes to boot, but you should see the startup screen before too long:

+
+Catalog Images
+--------------
+
+You may now want to install all the catalog images.  These allow you to view an image of every object in the catalog system.  For more details please see the `Catalog Image Download <https://github.com/brickbots/PiFinder/blob/main/docs/user_guide_setup.md#catalog-image-download>`_ instructions.
