## What it is
The original repository for Go's HTTP/2 protocol implementation, which has since moved into the golang.org/x/net module and the Go standard library. This old tree is kept working only for legacy importers and directs users to import golang.org/x/net/http2 instead.

## Use cases
- enable HTTP/2 support in a Go web server
- make HTTP/2 requests from a Go HTTP client
- debug HTTP/2 framing issues in Go applications
- maintain legacy code that imports the old bradfitz/http2 path
- understand how HTTP/2 is implemented in Go

## When to choose
- you are maintaining old code that still imports github.com/bradfitz/http2
- you need a historical reference of the original Go HTTP/2 implementation

## When to avoid
- starting any new Go project - use golang.org/x/net/http2 or rely on net/http's built-in HTTP/2 in Go 1.6+
- you need the latest features or bug fixes - development happens in the Go repo and x/net
- you want to file bugs or contribute - the project uses Gerrit, not GitHub pull requests

## Facets

- function: http-server, http-client, middleware
