 # fastglue
 
-Fastglue is a "glue" wrapper over [fasthttp](https://github.com/valyala/fasthttp) and [fasthttprouter](https://github.com/fasthttp/router).
-
-Currently, fastglue is successfully used at [Zerodha](https://zerodha.com) in production serving millions of requests per second.
+## Overview [![Go Reference](https://pkg.go.dev/badge/github.com/zerodha/fastglue.svg)](https://pkg.go.dev/github.com/zerodha/fastglue) [![Zerodha Tech](https://zerodha.tech/static/images/github-badge.svg)](https://zerodha.tech)
+
+fastglue is an opinionated, bare bones wrapper that glues together [fasthttp](https://github.com/valyala/fasthttp)
+and [fasthttprouter](https://github.com/fasthttp/router) to act as a micro HTTP framework. It helps eliminate
+boilerplate that would otherwise be required when using these two libraries to
+write HTTP servers. It enables:
+
+- Performance benefits of fasthttp + fasthttprouter.
+- Pre/post middleware hooks on HTTP handlers.
+- Simple middlewares for validating (existence, length range) of params in HTTP
+  requests.
+- Functions for unmarshalling request payloads (Form encoding, JSON, XML) into
+  arbitrary structs.
+- Shortcut functions for registering handlers, `GET()`, `POST()` etc.
+- Shortcut for fasthttp listening on TCP and Unix sockets.
+- Shortcut for graceful shutdown hook on the fasthttp server.
+- Opinionated JSON API response and error structures.
+- Shortcut functions for sending strings, bytes, JSON in the envelope structure
+  without serialization or allocation.
