 It is equivalent to provide a parameter using the three approaches below.
 
+In addition, you can provide configs by both configuration file / pubspec.yaml and command line at the same time.
+The latter takes precedence when in conflict.

+# Modules
+
+:::info
+Currently, only commonly used module syntaxes are supported
+(feel free to create an issue if you need something not implemented yet).
+When implementing more sophisticated module grammar parser,
+it is possible to have breaking changes caused by improved understanding of modules not following semver.
+However, such changes are usually trivial to migrate.
+:::
+
+## Support of modules
+
+Since `flutter_rust_bridge` utilizes cargo-expand to understand the source code,
+many Rust module grammar are supported automatically.
+For example, `mod something;` and `mod another_inline_module { ... }` are both allowed.
+
+## Support of `pub use`
+
+It is supported to have code like:
+
+* `pub use a::b::c;` (normal imports)
+* `pub use a::b::*;` (wildcard imports)
+* `pub use a::{b, x::{y,z}};` (multiple imports even with such nesting)

 The `impl A for B` is supported, and is translated to a `class B implements A`.
 In addition, the methods inside this `impl` block will also be converted automatically.
 
+## Unignore a function
+
+Some trait implementations are ignored by default to avoid generating meaningless things to Dart side such as `clone` and `deref`.
+However, if a function is ignored while you want it, you can put arbitrary attributes on it to tell flutter_rust_bridge you want it.
+For example, `#[frb] fn f() { .. }` suffices. Attributes with real contents like `#[frb(sync)] fn f() { .. }` also works.

 ## Example
 
 For example, suppose we write down:
