 MoveIt is mainly supported on Linux, and the following build instructions support in particular:
 
 - Ubuntu 22.04 / ROS 2 Humble Hawksbill (LTS)
-- Ubuntu 22.04 / ROS 2 Iron Irwini (stable)
 - Ubuntu 24.04 / ROS 2 Jazzy Jalisco (Recommended LTS)
 - Ubuntu 24.04 / ROS 2 Rolling Ridley (Continuously Updated. Use this to access latest features.)
 
 In the future, we would like to expand our source build instructions to more OS's, please contribute instruction write-ups to [this repo](https://github.com/moveit/moveit.ros.org).
 
-These instructions assume you are running on Ubuntu 24.04 (Jazzy, Rolling). However, the same build commands should apply to Humble and Iron builds on Ubuntu 22.04.

 ## Prerequisites
 
 ### Install <img src="/assets/install_page/ros_logo.jpeg"/>
 
 Install ROS 2 [Jazzy](https://docs.ros.org/en/jazzy/Installation/Ubuntu-Install-Debians.html), or [Rolling](https://docs.ros.org/en/rolling/Installation/Ubuntu-Install-Debians.html) following the installation instructions.
 
-We recommend Jazzy as the latest and stable LTS distribution, or alternatively Rolling for continuous development including contributions to MoveIt 2. Currently the [main branch](https://github.com/moveit/moveit2) supports Rolling, Jazzy, Iron, and Humble (note that Iron and Humble will be phased out once incompatible, as we only ensure support for the latest LTS versions).
-However, since the main branch is used for development, the MoveIt API is not stable. For stable versions, please use the distro branches [humble](https://github.com/moveit/moveit2/tree/humble), or [iron](https://github.com/moveit/moveit2/tree/iron). A stable branch for Jazzy will be established soon as well.
