+#
+# This script should be run via curl:
+# sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
+# or wget:
+# sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
+#
+# As an alternative, you can first download the install script and run it afterwards:
+# wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
+# sh install.sh
+#
+# You can tweak the install behavior by setting variables when running the script. For
+# example, to change the path to the Oh My Zsh repository:
+# ZSH=~/.zsh sh install.sh
+#
+# Respects the following environment variables:
+# ZSH - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
+# REPO - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
+# REMOTE - full remote URL of the git repo to install (default: GitHub via HTTPS)
+# BRANCH - branch to check out immediately after install (default: master)
+#
+# Other options:
+# CHSH - 'no' means the installer will not change the default shell (default: yes)
+# RUNZSH - 'no' means the installer will not run zsh after the install (default: yes)
+# KEEP_ZSHRC - 'yes' means the installer will not replace an existing .zshrc (default: no)
+#
+# You can also pass some arguments to the install script to set some these options:
+# --skip-chsh: has the same behavior as setting CHSH to 'no'
+# --unattended: sets both CHSH and RUNZSH to 'no'
+# --keep-zshrc: sets KEEP_ZSHRC to 'yes'
+# For example:
+# sh install.sh --unattended
+#
