 *Integraal* aims to provide generic and efficient tools for [numerical integration][NI] in the Rust Programming
 Language.
 
 [NI]: https://en.wikipedia.org/wiki/Numerical_integration
 
 ## Quickstart
 
+You can add Integraal to your project by adding this to its manifest:
+
+```
+# Cargo.toml
+
+[dependencies]
+# other deps...
+integraal = { version = "*" }
+
+```
+
+The Rust Doc is available for usage instructions, examples are provided with the source code / in the repository.
