+### How to make Powerlevel10k look like robbyrussell Oh My Zsh theme?
+
+Use [this config](
+  https://github.com/romkatv/powerlevel10k/blob/master/config/p10k-robbyrussell.zsh).
+
+You can either download it, save as `~/.p10k.zsh` and `source ~/.p10k.zsh` from `~/.zshrc`, or
+source `p10k-robbyrussell.zsh` directly from your cloned `powerlevel10k` repository.
