+#Installer lite
+A simple installation app creator for your Windows app.
+Takes the bytes that make up your binary and store it inside the installer binary, then it writes the file down in a requested location.
+how to use:
+- First create a `./installer/installer.rs` file in your crates root directory.
+- Add the binary to your `Cargo.toml` as such:
+```toml
+[package]
+name = "demo-app"
+version = "1.0.0"
+edition = "2021"
+# First add the app you want to package as a bin
+[[bin]]
+name = "demo_app"
+path = "src/main.rs"
+
+# Then add the installer as such, must be second so it always
+# builds after your main one
+[[bin]]
+name = "demo_app_installer"
+path = "installer/installer.rs"
+
+# and ofcourse add the dependency
+[dependencies]
+installer_lite = "1.0.0"
+```
+- inside the `installer.rs`:
+```rs
+use installer_lite::Installer;
+use std::{env, path::PathBuf};
+
+/* Make sure your app is built first, then include it's bytes */
+static EXECUTABLE: &'static [u8] = include_bytes!("../target/release/demo_app.exe");
+fn main() {
+    let app_name = env!("CARGO_PKG_NAME");
+
+    let mut installer = Installer::new(
+        EXECUTABLE,
+        None, // Defaults to C:\Program Files (x86)
+        app_name.to_string(),
+    );
+    /* Support for pre and post install custom functions */
+    installer.add_pre_install_function(Box::from(|| {
+        println!("STARTING INSTALLATION HEHE");
+        let console_output = "STARTING INSTALLATION HEHE".to_owned();
+        return console_output;
+    }));
+    /* Start the installer, maybe handle error cases */
+    installer.start().expect("Installation somehow failed");
+}
+```
