-Rusqlite is an ergonomic wrapper for using SQLite from Rust. It attempts to expose
-an interface similar to [rust-postgres](https://github.com/sfackler/rust-postgres).
+Rusqlite is an ergonomic wrapper for using SQLite from Rust.
+
+## Usage
+
+In your Cargo.toml:
+
+```toml
+[dependencies]
+# `bundled` causes us to automatically compile and link in an up to date
+# version of SQLite for you, which avoids many common build issues, and
+# avoids depending on the version of SQLite on the users system, which may
+# be old or missing. However, it's not ideal for all scenarios and in
+# particular, generic libraries built around `rusqlite` should probably
+# not enable it; it's a choice that should *usually* be left up to
+# the application that actually manages the database, which is why it
+# is not a default feature.
+rusqlite = { version = "0.27.0", features = ["bundled"] }
+```
+
+Simple example usage:
 
 ```rust
-use rusqlite::{params, Connection, Result};
+use rusqlite::{Connection, Result};
