+## Function library
+- The library has one function: `rpfixer::idk::fix`. Use a `Vec<u8>` in it.
+#### Example code
+```rust
+use std::fs;
+fn main() {
+    let frfr = fs::read("filepath.png").expect("wtf the path doesnt exist");
+    let mut fr = rpfixer::idk::fix(frfr);
+    fs::write(thatpath, fr).expect("file could not write btw");
+}
+```
 
 
 # Syntax
 
 Check `--help` for syntax.
 
-# I want some logs for checking wtf is happening
+Example syntax:
 
-Pipe your output to a new filename. 
-
-Note: It might not work for SOME linux shells. But major ones e.g. `zsh`,`bash` support it.
-
-`rpfixer --path ~/somedir/ --debug > ~/log.txt`
