+# sparo zsh plugin
+
+This "sparo" zsh plugin provides many aliases just like [git zsh plugin](https://github.com/ohmyzsh/ohmyzsh/blob/master/plugins/git/README.md) does.
+
+## Install & Update
+
+```shell
+sh -c "$(curl -fsSL https://raw.githubusercontent.com/tiktok/sparo/main/zsh-plugin/sparo/install.sh)" "" main
+```
+
+To use it, add `sparo` to the plugins array in your zshrc file:
+
+**~/.zshrc**
+
+```shell
+plugins=(... sparo)
+```
+
+Or, manually load it by appending the following code to your zshrc file:
+
+**~/.zshrc**
+
+```shell
+source $ZSH/custom/plugins/sparo/sparo.plugin.zsh
+```
