-* ROS2 Humble
-    * Follow the standard ROS2 humble install process. Linux recommended.
-        * https://docs.ros.org/en/humble/Installation.html
-* Colcon
-    * `$ sudo apt update`
-    * `$ sudo apt install python3-colcon-common-extensions`
-* Configured Static IP for Ubiquiti bullet (Process varies by OS)
-    * IP Address: 192.168.1.x
-        * This can be just about anything not already in use. I recommend something 30-39
-    * Net Mask: 255.255.255.0
-    * Gateway: 192.168.1.0
+## Software Prerequisites
 
-## Launching with ANCHOR
+You need either [ROS2 Humble](https://docs.ros.org/en/humble/index.html)
+with [rosdep](https://docs.ros.org/en/humble/Tutorials/Intermediate/Rosdep.html#rosdep-installation)
+or [Nix](https://nixos.org/download/#nix-install-linux) installed. We recommend
+using Nix.
 
-ANCHOR (Active Node Controller Hub and Operational Relay)
-Allows for launching all nodes on the rover simulataneously. Additionally, all controls will run through the core's NUC and MCU.
-<br>
-1. SSH to core
-    * Core1: `ssh clucky@192.168.1.69`
-    * Core2: `ssh clucky@192.168.1.70`
-    * Password: \<can be found in the rover-Docs repo under documentation>
-2. Navigate to rover-ros2 workspace
-    * `cd rover-ros2`
-3. Source the workspace
-    * `source install/setup.bash`
-4. Launch ANCHOR
-    * `ros2 launch rover_launch.py mode:=anchor`
+### Nix
 
-## Launching as Standalone
+With Nix, all you have to do is enter the development shell:
 
-For use when running independent modules through their respective computers (pi/NUC) without ANCHOR.
+```bash
+$ cd path/to/rover-ros2
+$ nix develop
+```
 
-1. SSH to the the module's computer
-    * Core1: `ssh clucky@192.168.1.69`
-    * Core2: `ssh clucky@192.168.1.70`
-    * Arm: `ssh arm@192.168.1.70`
-    * Bio: \<TBD>
-    * Password: \<can be found in the rover-Docs repo under documentation>
-2. Run the main node (this sends commands to the MCU)
-    * Navigate to the rover-ros2 workspace (location may vary)
-        * `cd rover-ros2`
-    * Source the workspace
-        * `source install/setup.bash`
-    * Start the node
-        * ARM: `ros2 launch rover_launch.py mode:=arm`
-        * CORE: `ros2 launch rover_launch.py mode:=core`
-        * BIO: `ros2 launch rover_launch.py mode:=bio`
+### ROS2 Humble + rosdep
 
-## Running Headless
+With ROS2 Humble, start by using rosdep to install dependencies:
 
-Headless control nodes (for ARM and CORE) allow running of the module on-rover without the operator having ROS2 installed on their machine. You will need a laptop to connect to the pi/NUC in order to launch headless but it can be disconnected after the nodes are spun up.
-<br>
-1. SSH to the the module's computer
-    * Core1: `ssh clucky@192.168.1.69`
-    * Core2: `ssh clucky@192.168.1.70`
-    * Arm: `ssh arm@192.168.1.70`
-    * Password: \<can be found in the rover-Docs repo under documentation>
-2. Run the  headless node
-    * You must have ANCHOR or the module's Standalone node running
-    * Open a new terminal (SSH'd to the module)
-    * Navigate to rover-ros2 workspace
-        * `cd rover-ros2`
-    * Source the workspace
-        * `source install/setup.bash`
-    * Run the node (ensure controller is connected and on x-input mode)
-        * CORE: `ros2 run core_pkg headless`
-        * ARM: `ros2 run arm_pkg headless`
+```bash
+  # Setup rosdep
+$ sudo rosdep init  # only run if you haven't already
+$ rosdep update
+  # Install dependencies
+$ cd path/to/rover-ros2
+$ rosdep install --from-paths src -y --ignore-src
+```
 
-## Connecting the GuliKit Controller
+## Running
 
-Connecting the GuliKit Controller (Recommended)
+```bash
+$ colcon build
+$ source install/setup.bash
+  # main launch files:
+$ ros2 launch anchor_pkg rover.launch.py  # Must be run on a computer connected to a MCU on the rover.
+$ ros2 run headless_pkg headless_full  # Optionally run in a separate shell on the same or different computer.
+```
 
-* Connect controller to pc with USB-C
+### Using the Mock Connector
+
+Anchor provides a mock connector meant for testing and scripting purposes. You can select the mock connector by running anchor with this command:
+
+```bash
+$ ros2 launch anchor_pkg rover.launch.py connector:="mock"
+```
+
+To see all data that would be sent over the CAN network (and thus to the microcontrollers), use this command:
+
+```bash
+$ ros2 topic echo /anchor/to_vic/debug
+```
+
+To send data to the mock connector (as if you were a ROS2 node), use the normal relay topic:
+
+```bash
+$ ros2 topic pub /anchor/to_vic/relay astra_msgs/msg/VicCAN '{mcu_name: "core", command_id: 50, data: [0.0, 2.0, 0.0, 1.0]}'
+
+```
+
+To send data to the mock connector (as if you were a microcontroller), publish to the dedicated topic:
+
+```bash
+$ ros2 topic pub /anchor/from_vic/mock_mcu astra_msgs/msg/VicCAN '{mcu_name: "arm", command_id: 55, data: [0.0, 450.0, 900.0, 0.0]}'
+```
+
+### Testing Serial
+
+You can fake the presence of a Serial device (i.e., MCU) by using the following command:
+
+```bash
+$ socat -dd -v pty,rawer,crnl,link=/tmp/ttyACM9 pty,rawer,crnl,link=/tmp/ttyOUT
+```
+
+When you go to run anchor, use the `serial_override` ROS2 parameter to point it to the fake serial port, like so:
+
+```bash
+$ ros2 launch anchor_pkg rover.launch.py connector:=serial serial_override:=/tmp/ttyACM9
+```
+
+### Testing CAN
+
+You can create a virtual CAN network by using the following commands to create and then enable it:
+
+```bash
+sudo ip link add dev vcan0 type vcan
+sudo ip link set vcan0 up
+```
+
+When you go to run anchor, use the `can_override` ROS2 parameter to point it to the virtual CAN network, like so:
+
+```bash
+$ ros2 launch anchor_pkg rover.launch.py connector:=can can_override:=vcan0
+```
+
+Once you're done, you should delete the virtual network so that anchor doesn't get confused if you plug in a real CAN adapter:
+
+```bash
+$ sudo ip link delete vcan0
+```
+
+### Connecting the GuliKit Controller
+
+These instructions apply to the black XBox-style GuliKit controller, primarily used for controlling Arm through Basestation.
+
+* Connect the controller to your PC with a USB-C cable
 * Select the "X-Input" control mode (Windows logo) on the controller.
-* Hold the button next to the symbols (windows, android, switch, etc...)
-* You'll need to release the button and press down again to cycle to the next mode

+
+## Common Problems/Troubleshooting
+
+**Q**: When I try to launch the nodes, I receive a `package '' not found` error.
+
+A: Make sure you have sourced the workspace in the current shell:
+
+```bash
+$ source install/setup.bash  # or setup.zsh if using ZSH
+```
+
+**Q**: When I try to launch the nodes, I receive several `FileNotFoundError: [Errno 2]` errors.
+
+A: Sometimes the install files get messed up by running `colcon build` in different shells or updating packages. Try running the following commands to clean up your local build files:
+
+```bash
+$ rm -rf build/ install/
+$ colcon build
+```
+
+**Q**: When I run `colcon build` after the above suggestion, I receive several of the following errors:
+
+```bash
+[0.557s] WARNING:colcon.colcon_ros.prefix_path.ament:The path '' in the environment variable AMENT_PREFIX_PATH doesn't exist
+```
+
+A: Don't worry about it. If you had the workspace sourced, ROS2 will complain about the workspace install files not existing anymore after you deleted them. They will be re-created by `colcon build`, after which you can run `source install/setup.bash` to source the new install files.
+
+**Q**: When I try to launch Anchor, I receive the following errors:
+
+```bash
+[anchor-5] [INFO] [1762239452.937881841] [anchor]: Unable to find MCU...
+...
+[ERROR] [anchor-5]: process has died [pid 101820, exit code 1, cmd '.../rover-ros2/install/anchor_pkg/lib/anchor_pkg/anchor --ros-args -r __node:=anchor --params-file /tmp/launch_params_nmv6tpw4'].
+[INFO] [launch]: process[anchor-5] was required: shutting down launched system
+[INFO] [bio-4]: sending signal 'SIGINT' to process[bio-4]
+[INFO] [ptz-3]: sending signal 'SIGINT' to process[ptz-3]
+[INFO] [core-2]: sending signal 'SIGINT' to process[core-2]
+[INFO] [arm-1]: sending signal 'SIGINT' to process[arm-1]
+...
+```
+
+A: To find a microcontroller to talk to, Anchor sends a ping to every Serial port on your computer. If it does not receive a 'pong' in less than one second, then it aborts. There are a few possible fixes:
+
+- Keep trying to run it until it works
+- Run `lsusb` to see if the microcontroller is detected by your computer.
+- Run `ls /dev/tty*0` to see if there is a valid Serial port enumerated for the microcontroller.
+- Check if you are in the `dialout` group (or whatever group shows up by running `ls -l /dev/tty*`).
+
+## Packages
+
+- [anchor\_pkg](./src/anchor_pkg) - Handles Serial communication between the various other packages here and the microcontroller.
+- [arm\_pkg](./src/arm_pkg) - Relays controls and sensor data for the arm (socket and digit) between anchor and basestation/headless.
+- [astra\_descriptions](./src/astra_descriptions) - Submodule with URDF-related packages.
+- [bio\_pkg](./src/bio_pkg) - Like arm_pkg, but for CITADEL and FAERIE
+- [core\_pkg](./src/core_pkg) - Like arm_pkg, but for Core
+- [headless\_pkg](./src/headless_pkg) - Simple, non-graphical controller node to work in place of basestation when controlling the rover by itself. This is autostarted with anchor to allow for setup-less control of the rover.
+- [latency\_tester](./src/latency_tester) - A temporary node to test comms latency over ROS2, Serial, and CAN.
+- [ros2\_interfaces\_pkg](./src/ros2_interfaces_pkg) - Contains custom message types for communication between basestation and the rover over ROS2. (being renamed to `astra_msgs`).
+- [servo\_arm\_twist\_pkg](./src/servo_arm_twist_pkg) - A temporary node to translate controller state from `ros2_joy` to `Twist` messages to control the Arm via IK.

-       A macro like this will expand to a set of link and joint definitions, and to additional
-       Gazebo-related extensions (sensor plugins, etc).  The macro takes an argument, name,
-       that equals "base", and uses it to generate names for its component links and joints
-       (e.g., base_link).  The xacro:included origin block is also an argument to the macro.  By convention,
-       the origin block defines where the component is w.r.t its parent (in this case the parent
-       is the world frame). For more, see http://www.ros.org/wiki/xacro -->
