 # ros2_numpy
 This project is a fork of [ros_numpy](https://github.com/eric-wieser/ros_numpy)
 to work with ROS 2. It provides tools for converting ROS messages to and from
-numpy arrays. Contains two functions:
+numpy arrays. In the ROS 2 port, the module has been renamed to
+`ros2_numpy`. Users are encouraged to update their application code to import
+the module as shown below.
+
+ROS 2:
+
+```
+import ros2_numpy as rnp
+```
+
+ROS 1:
+
+```
+import ros_numpy as rnp
+```
+
+Prefacing your calls like `rnp.numpify(...)` or `rnp.msgify(...)` should help
+future proof your codebase while the ROS 1 and ROS 2 ports are API compatible.
+
+The ROS 2 port has been bootstrapped as version `2.0.3`. The `MAJOR`
+version has been set to `2` to indicate ROS 2 and the `MINOR` and `PATCH`
+versions match the ROS 1 version from which the ROS 2 port was
+bootstrapped. The reasoning behind this is to allow for creating tags in this
+fork that can be released into the ROS 2 distribution while not conflicting
+with existing tags on the upstream repository. A release into Foxy is still
+pending.
+
+This module contains two core functions:
 
 * `arr = numpify(msg, ...)` - try to get a numpy object from a message
 * `msg = msgify(MessageType, arr, ...)` - try and convert a numpy object to a message
