+* For things you do not want rustfmt to mangle, use `#[rustfmt::skip]`
+* To prevent rustfmt from formatting a macro,
+  use `#[rustfmt::skip::macros(target_macro_name)]`
+
+  Example:
 
     ```rust
-    #[rustfmt::skip]  // requires nightly Rust and #![feature(tool_attributes)] in crate root
-    #[cfg_attr(rustfmt, rustfmt_skip)]  // works in stable

+    fn main() {
+        let macro_result1 = html! { <div>
+    Hello</div>
+        }.to_string();
     ```
 * When you run rustfmt, place a file named `rustfmt.toml` or `.rustfmt.toml` in
   target file directory or its parents to override the default settings of
   rustfmt. You can generate a file containing the default configuration with
-  `rustfmt --dump-default-config rustfmt.toml` and customize as needed.
+  `rustfmt --print-config default rustfmt.toml` and customize as needed.
 * After successful compilation, a `rustfmt` executable can be found in the
   target directory.
 * If you're having issues compiling Rustfmt (or compile errors when trying to
   install), make sure you have the most recent version of Rust installed.
 
-* If you get an error like `error while loading shared libraries` while starting
-  up rustfmt you should try the following:

-  On Windows (Git Bash/Mingw):

-  ```
-  export PATH=$(rustc --print sysroot)/lib/rustlib/x86_64-pc-windows-gnu/lib/:$PATH

+  Options:
 
-  (Substitute `x86_64` by `i686` and `gnu` by `msvc` depending on which version of rustc was used to install rustfmt).
