+# Amp (AmpCode)
+
+Amp is a frontier coding agent for your terminal and editor, built by Sourcegraph.
+
+- **Multi-Model** Sonnet, GPT-5, fast models—Amp uses them all, for what each model is best at.
+- **Opinionated** You're always using the good parts of Amp. If we don't use and love a feature, we kill it.
+- **On the Frontier** Amp goes where the models take it. No backcompat, no legacy features.
+- **Threads** You can save and share your interactions with Amp. You wouldn't code without version control, would you?
+
+## Prerequisites
+
+- Node.js 18+ so `npx` can run the adapter
+- Ensure the `AMP_EXECUTABLE` environment variable points at your Amp binary (or place `amp` on `PATH`)
+
