+### Rust Tip: include_str! Macro
+
+`include_str!` is a macro that reads the content of a file at compile time, and embeds it as a `&'static str`
+
+#### When it's useful
+
+For bundling static assets (like configuration files, templates, or small images) directly into your executable.
+
+This avoids runtime file I/O and simplifies deployment as you don't need to ship separate asset files.
+
+
+```rust
+// Rust Bytes Issue 71: include_str! Macro
+
+const GREETING: &str = include_str!("data/greeting.txt");
+// Assuming you have a file `data/greeting.txt` in your project root with "Hello, Rust!"
+
+fn main() {
+    println!("{}", GREETING);
+}
+```
+
