+# ``GRPCNIOTransportHTTP2Posix``
+
+HTTP/2 client and server transports built on top of SwiftNIO's `NIOPosix` module.
+
+## Overview
+
+This module provides HTTP/2 transports for client and server built on top SwiftNIO's `NIOPosix`
+module and uses SwiftNIO's `NIOSSL` module to provide TLS.
+
+The two transport types are:
+- `HTTP2ClientTransport.Posix`, and
+- `HTTP2ServerTransport.Posix`.
+
+### Availability
+
+These transports are available on the following platforms:
+
+- Linux (Ubuntu, CentOS, Amazon Linux, Red Hat Universal Base Image)
+- macOS 15.0+
+- iOS 18.0+
+- tvOS 18.0+
+- watchOS 11.0+
+
+
+### Getting started
+
+Bootstrapping a client or server is made easier using the `.http2NIOPosix` shorthand:
+
+```swift
+// Create a server resolving "localhost:31415" using the default transport
+// configuration and default TLS security configuration.
+try await withGRPCClient(
+  transport: try .http2NIOPosix(
+    target: .dns(host: "localhost", port: 31415),
+    transportSecurity: .tls
+  )
+) { client in
+  // ...
+}
+
+// Create a plaintext server listening on "127.0.0.1" on any available port
+// modifying the default configuration to set max concurrent streams to 256.
+try await withGRPCServer(
+  transport: .http2NIOPosix(
+    address: .ipv4(host: "127.0.0.1", port: 0),
+    transportSecurity: .plaintext,
+    config: .defaults { config in
+      config.http2.maxConcurrentStreams = 256
+    }
+  ),
+  services: [...]
+) { server in
+  // ...
+}
+```

+HTTP/2 client and server transports built on top of SwiftNIO's `NIOTransportServices` module.
+
+## Overview
+
+This module provides HTTP/2 transports for client and server built on top SwiftNIO's
+`NIOTransportServices` module which provide TLS via Apple's Network framework.
+
+The two transport types are:
+- `HTTP2ClientTransport.TransportServices`, and
+- `HTTP2ServerTransport.TransportServices`.
+
+### Availability
+
+These transports are available on the following platforms:
+
+- macOS 15.0+
+- iOS 18.0+
+- tvOS 18.0+
+- watchOS 11.0+
+
+
+### Getting started
+
+Bootstrapping a client or server is made easier using the `.http2NIOTS` shorthand:
+
+```swift
+// Create a server resolving "localhost:31415" using the default transport
+// configuration and default TLS security configuration.
+try await withGRPCClient(
+  transport: try .http2NIOTS(
+    target: .dns(host: "localhost", port: 31415),
+    transportSecurity: .tls
+  )
+) { client in
+  // ...
+}
+
+// Create a server listening on "127.0.0.1" on any available port
+// using default plaintext security configuration.
+try await withGRPCServer(
+  transport: .http2NIOTS(
+    address: .ipv4(host: "127.0.0.1", port: 0),
+    transportSecurity: .plaintext,
+    config: .defaults { config in
+      config.http2.maxConcurrentStreams = 256
+    }
