# Twisted Documentation

- Introduction
  - Executive summary
    Connecting your software - and having fun too!
- Getting Started
  - Writing a TCP server
    Basic network servers with Twisted.
  - Writing a TCP client
    And basic clients.
  - Test-driven development with Twisted
    Code without tests is broken by definition; Twisted makes it easy to test your network code.

  - Setting up the TwistedQuotes application
  - Designing a Twisted application
- Networking and Other Event Sources
  - Twisted Internet
    A brief overview of the `twisted.internet` package.

    Add some security to your network transport.
  - UDP Networking
    Multicast too!
  - Using processes
    Launching sub-processes, the correct way.
  - Introduction to Deferreds
    Like callback functions, only a lot better.
  - Deferred reference
    In-depth information on Deferreds.
  - Generating deferreds
    More about Deferreds.
  - Scheduling
    Timeouts, repeated events, and more: when you want things to happen later.
  - Using threads
    Running code in threads, and interacting with Twisted in a thread-safe manner.
  - Producers and Consumers: Efficient High-Volume Streaming
    How to pause when buffers fill up.
  - Choosing a reactor and GUI toolkit integration
    GTK+, Windows, epoll() and more: use your GUI of choice, or a faster event loop.
- High-Level Infrastructure
  - Getting Connected with Endpoints
    Create configurable applications that support multiple transports (e.g. TCP and SSL).
  - Interfaces and Adapters (Component Architecture)
    When inheritance isn't enough.
  - Cred: Pluggable Authentication
    Implementing authentication and authorization that is configurable, pluggable and re-usable.
  - Twisted's plugin architecture
    A generic plugin system for extendable programs.
- Deploying Twisted Applications
  - Helper programs and scripts (twistd, ..)
    `twistd` lets you daemonize and run your application.
  - Using the Twisted Application Framework
    Writing code that `twistd` can run.
