+## Install
+
+`atuin` needs a recent version of Rust + Cargo! It's best to use rustup for.
+
+```
+cargo install atuin
+```
+
+and then add this to your ~/.zshrc
+
+```
+export ATUIN_SESSION=$(atuin uuid)
+
+_atuin_preexec(){
+	id=$(atuin history start $1)
+	export ATUIN_HISTORY_ID="$id"

+## Usage
+
+### Import history
+
+```
+atuin import auto # detect shell, then import
+atuin import zsh  # specify shell
+```
+
+### List history
+
+```
+atuin history list
