How to: How do I install Powerlevel10k on a machine without Internet access?
1. Run this command on the machine without Internet access:
   ```sh
   uname -sm | tr '[A-Z]' '[a-z]'
   ```
2. Run these commands on a machine connected to the Internet after replacing the value of
   `target_uname` with the output of the previous command:
   ```sh
   target_uname="replace this with the output of the previous command"
   git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
   GITSTATUS_CACHE_DIR="$HOME"/powerlevel10k/gitstatus/usrbin ~/powerlevel10k/gitstatus/install -f -s "${target_uname% *}" -m "${target_uname#* }"
   ```
3. Copy `~/powerlevel10k` from the machine connected to the Internet to the one without Internet
   access.
4. Add `source ~/powerlevel10k/powerlevel10k.zsh-theme` to `~/.zshrc` on the machine without
   Internet access:
   ```zsh
   echo 'source ~/powerlevel10k/powerlevel10k.zsh-theme' >>~/.zshrc
   ```
5. If `~/.zshrc` on the machine without Internet access sets `ZSH_THEME`, remove that line.
   ```zsh
   sed -i.bak '/^ZSH_THEME=/d' ~/.zshrc
   ```

To update, remove `~/powerlevel10k` on both machines and repeat steps 1-3.
