7 ‘Marionette’ means different a few different things, depending
8 on who you talk to, but the overall scope of the project involves
11 * [_Marionette_] is a Firefox remote protocol to communicate with,
12 instrument, and control Gecko-based applications such as Firefox
13 and Firefox for mobile. It is built in to the application and
14 written in JavaScript.
16 It serves as the backend for the geckodriver WebDriver implementation,
17 and is used in the context of Firefox UI tests, reftesting,
18 Web Platform Tests, test harness bootstrapping, and in many
19 other far-reaching places where browser instrumentation is required.
21 * [_geckodriver_] provides the HTTP API described by the [WebDriver
22 protocol] to communicate with Gecko-based applications such as
23 Firefox and Firefox for mobile. It is a standalone executable
24 written in Rust, and can be used with compatible W3C WebDriver clients.
26 * [_webdriver_] is a Rust crate providing interfaces, traits
27 and types, errors, type- and bounds checks, and JSON marshaling
28 for correctly parsing and emitting the [WebDriver protocol].

42 Because there are many moving parts involved remote controlling
43 a web browser, it can be challenging to a new contributor to know
44 where to start. Please don’t hesitate to [ask questions]!
46 The canonical source code repository is [mozilla-central]. Bugs are
47 filed in the [Testing :: Marionette] component on Bugzilla. We also
48 have a curated set of [good first bugs] you may consider attempting first.
50 We have collected a lot of good advice for working on Marionette
51 code in our [code style document], which we highly recommend you read.
