+Save filesystem and asset scopes and restore them when the app is reopened.
 
 ## Install
 
-```
+There are three general methods of installation that we can recommend.
 
+1. Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked)
+2. Pull sources directly from Github using git tags / revision hashes (most secure)
+3. Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use)
+
+Install the Core plugin by adding the following to your `Cargo.toml` file:
+
+`src-tauri/Cargo.toml`
+```toml
+[dependencies]
+tauri-plugin-persisted-scope = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "dev" }
 ```
 
 ## Usage
 
+First you need to register the core plugin with Tauri:
+
+`src-tauri/src/main.rs`
+```rust
+fn main() {
+    tauri::Builder::default()
+        .plugin(tauri_plugin_persisted_scope::init())
+        .run(tauri::generate_context!())
+        .expect("error while running tauri application");
+}
 ```
 
-```
+Afterwards the plugin will automatically save and restore filesystem and asset scopes.
