+# incria
+
+Incria is a library for incremental computation.
+It lets you record what a calculation depends on and then only re-run that calculation once one of those dependencies has changed.
+
+This is similar to the [query system used by the Rust compiler](https://rustc-dev-guide.rust-lang.org/query.html), but implemented using async.
+By seperating the tracking of dependencies from the calculation logic, you can write clean code that re-runs only when it needs to, and can be parallelised with little extra work.
+
+For more info, read the rustdoc or check the [/examples](examples).
