 #### Adding New Users
 
-If you're sharing Stretch with other developers, it's a good idea to make an account for yourself and your team members. Your code and data will be password protected in your own account, and other developers can change or upgrade their own Stretch SDK without affecting yours and accidentally breaking your code.
-
-!!! warning
-
-    User accounts cannot completely insulate your account from changes in another. For example, if the robot's tool was changed, your account would have an outdated configuration for what tool is attached to the robot. A non-exhaustive list of changes that could break/affect accounts:
-
-      - Making hardware changes to the robot
-      - Updating the firmware
-      - Installing/changing [APT packages](#apt-package-manager)
-
-Start by logging into the admin Hello Robot user. Go to Users system settings and unlock adminstrator actions.

-
-Click "Add User..." and complete the subsequent form.

-
-Log out and back in as the new user. Open a terminal and execute the following to pull down the Stretch Install repository:
-
-```{.bash .shell-prompt .copy}
-git clone https://github.com/hello-robot/stretch_install ~/stretch_install
-```
-
-Make sure it's up-to-date:
-
-```{.bash .shell-prompt .copy}
-cd ~/stretch_install && git pull
-```
-
-Run the new user install script to set up the SDK for this new account:
-
-```{.bash .shell-prompt .copy}
-./stretch_new_user_install.sh
-```
-
-Finally, reboot the robot and run a system check in the new user account to confirm if everything was set up correctly.
-
-```{.bash .shell-prompt .copy}
-stretch_robot_system_check.py
-```
+If you're sharing Stretch with other developers, it can be helpful to create separate accounts for yourself and your team members. Check out the [Adding a New User](https://docs.hello-robot.com/0.3/installation/add_new_user/) guide.
