-Because Askama will generate Rust code from your template files,
-the crate will need to be recompiled when your templates change.
-This is supported by adding a build script, `build.rs`, to your crate.
-It needs askama as a build dependency:
-
-```rust
-extern crate askama;
-
-fn main() {
-    askama::rerun_if_templates_changed();
-}
 ```
 
 Now create a directory called `templates` in your crate root.
