+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES

+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+![Wireframe image of LRR](_images/inverted_lrr.png)
+
+ROS enabled robots are (really) expensive, preventing many aspiring robotic engineers using powerful ROS tools.
+
+Little Red Rover (LRR) is a highly capable, differential drive, ROS 2 robot designed for an amateur budget.
+While none of the rovers' specs are top of the line, LRR gives students, hobbyists, and educators a representative ROS 2 experience and an entry point into the wonderful world of research robotics.
+Extensive development tooling, example code / projects, and documentation is provided to smooth the learning curve.
+
+## Thanks <!-- {docsify-ignore} -->
+
+LRR is part of my Masters of Engineering (MEng) thesis for Cornell University.
+
+Special thanks to my advisor, [Professor Tapomayukh Bhattacharjee](https://robotics.cornell.edu/faculty/tapomayukh-bhattacharjee-bio/) of the [EmPRISE Lab](https://emprise.cs.cornell.edu/). LRR was inspired by his course, Foundations of Robotics, and his help on the project has been invaluable.

+# Quickstart
+
+This guide will get you setup with Little Red Rover, and should take less than an hour. In the end you'll have an autonomous robot running ROS's [NAV2 tools](). 
+
+## Unboxing / Assembly
+
+Included in the box you'll find the following:
+
+ * One circuit board
+ * One LD-20 lidar
+ * Two orange wheels
+ * Two motors with encoders
+ * One 18650 LiIon battery, 5000 mah
+ * One 4-pin JST GH 1.25mm straight across cable
+ * Two 6-pin JST PH 2.0mm reversed cables
+ * An assortment of 3D printed parts
+    - One front skid
+    - Two motor holders
+    - Two motor spacing shims
+    - Two motor attachment shims
+    - Two wheel spacers
+ * Three M3-8 machine screws
+ * One M2.5 hex wrench
+ * One USB-C to C charging cable
+
+With these parts in hand, you're ready to assembly your robot.
+
+TODO: Assembly video
+
+## Software
+
+### Dependencies
+
+Little Red Rover uses Docker as a compatability layer with your host operating system ([what is docker?]()).
+The steps for installing Docker differ depending on your host OS.
+
+TODO: Docker installation for Mac, windows, linux, ect
+
+For a new user, Docker can have a steep learning curve. Luckily, the [DevContainers]() project allows for seamless integration within your editor.
+VSCode has first class support for DevContainers, and is the recommended editor for LRR.
+
+TODO: VsCode installation for Mac, windows, linux, ect
+
+Once VSCode is installed, use the extension manager to install the DevContainers extension.
+
+TODO: How to install extension
+
+Lastly, LRR uses Git / Github for source code management. To download the source code, you must first install git. 
+
+TODO: How to install Git
+
+### Setting Up Your Development Environment
+
+Our first step is to download the LRR source. 
+
+TODO
+
+Next, we need to open the project in VSCode.
+
+TODO
+
+Finally, open the project using the DevContainers extension. This first installation will take some time (you're downloading all of Ubunutu and ROS2 after all).
+It's recommended to use a strong internet connection during this initial setup.
+
+TODO
+
+Congrats! Your development enviroment is now setup.
+
+### Connection to the Robot
+
+On first setup, and whenever you take your robot to a new location, a network connection needs to be configured.
+
+First, power on your robot. To do so, insert your battery and move the power switch (located just next to the USB port) to the on position.
+
+
+### Rock and Roll
+
+Now that the robot is setup, lets have some fun. To start a demo, run the following commands in your VSCode shell:
+
+To build the ROS2 project:
+
+bash
+```
+lrr_build
+```
+
+To run the demo:
+
+bash
+```
+lrr_run
+```
+
+Your robot is now running, but we have no way to see whats going on!
+For that, we use a program called [Foxglove]().
+
+## Caring for your robot
+
+### Battery Charging and Care
+
+LRR comes with a rechargable 5000 MAh lithium ion battery. To recharge the battery, attach the provided USB cable between the robot and a power source.
+LRR contains two red status LEDs for power, located next to the USB-C port.
+The first, labeled `PWR GOOD`, turns on when the USB-C connection is supplying ample power to the system.
+The second, labeled `CHARGING`, turns on when the battery is actively charging. Once your battery is fully charged, this light will turn off.
+
+> [!WARNING]
+> NEVER, ever ever ever, charge lithium batteries unattended.
+> Both LRR and the provided battery contain protection circuitry, but there is still a NON-ZERO CHANCE THAT THE BATTERY WILL CATCH FIRE.
+> This issue is intrinsic to all cells with high power density, and it is your responsibility to use them safely.
+
+### Storage and Transport
+
+Little Red Rover's packaging is carefully designed to protect your robot once its assembled. Remove and lose foam and place the robot back into the box for transport.
