+# Vanity 🧂⛏️
+
+Vanity is a CLI for mining vanity move addresses.
+
+Vanity is heavely inspired by [Create2Crunch](https://github.com/0age/create2crunch).
+
+## Installation
+
+```bash
+git clone https://github.com/movementlabsxyz/movement.git
+cd movement
+# Run it directly
+cargo run -p vanity --release -- move --starts-pattern <STARTS_PATTERN> --ends-pattern <ENDS_PATTERN>
+
+cd util/vanity
+# Add it to your path
+cargo install --path .
+```
