+An opinionated ROS2 C++ node template, optimised for ISC.
+
+# Instructions
+
+1. Clone repo inside your workspaces src directory (Ex. phnx_ws/src)
+2. `rosdep install --from-paths . --ignore-src -r -y` to install deps
+3. `colcon build` to make sure the repo builds before you mess with it
+4. Replace the following in both file names and code exactly and consistently. 
+   1. TODO_PACKAGE_NAME: Replace with the package name. Use snake case. Ex. `data_logger`
+   2. TODO_NODE_NAME: Replace with the node name. Use Pascal case. Ex. `DataLogger`
+5. `colcon build` again. If it builds, you are done
+6. Rename outer folder
+7. Review the optional dependencies, and remove what you do not need
+
+# Dependencies
+Some common extra dependencies are included. Review them and remove what you don't need.
+These are marked with TODO_EXTRA.
+
+# Features
+
+- Unit tests
+- ROS-Industrial github CI (will test units and lints)
+- C++ formatting via clangformat
+- A selection of sane lints
+- A single node setup in a multithreaded executor
+
+# File structure
+
+```

+
+tests/unit.cpp: Example file for unit tests. This is linked to the node and ros, so both can be used
