+
+  @moduledoc """
+  Generates LiveView, templates, and context for a resource.
+
+      mix phx.gen.live Accounts User users name:string age:integer
+
+  The first argument is the context module followed by the schema module
+  and its plural name (used as the schema table name).
+
+  The context is an Elixir module that serves as an API boundary for
+  the given resource. A context often holds many related resources.
+  Therefore, if the context already exists, it will be augmented with
+  functions for the given resource.
+
+  When this command is run for the first time, a `ModalComponent` and
+  `LiveHelpers` module will be created, along with the resource level
+  LiveViews and components, including an `IndexLive`, `ShowLive`, `FormComponent`
+  for the new resource.
+
+  > Note: A resource may also be split
+  > over distinct contexts (such as `Accounts.User` and `Payments.User`).
+
+  The schema is responsible for mapping the database fields into an
+  Elixir struct. It is followed by an optional list of attributes,
+  with their respective names and types. See `mix phx.gen.schema`
+  for more information on attributes.
+
+  Overall, this generator will add the following files to `lib/`:
+
+    * a context module in `lib/app/accounts.ex` for the accounts API
+    * a schema in `lib/app/accounts/user.ex`, with an `users` table
+    * a view in `lib/app_web/views/user_view.ex`
+    * a LiveView in `lib/app_web/live/user_live/show_live.ex`
+    * a LiveView in `lib/app_web/live/user_live/index_live.ex`
+    * a LiveComponent in `lib/app_web/live/user_live/form_component.ex`
+    * a LiveComponent in `lib/app_web/live/modal_component.ex`
+    * a helpers modules in `lib/app_web/live/live_helpers.ex`
+
+  ## The context app
+
+  A migration file for the repository and test files for the context and
+  controller features will also be generated.
+
+  The location of the web files (LiveView's, views, templates, etc) in an
+  umbrella application will vary based on the `:context_app` config located
+  in your applications `:generators` configuration. When set, the Phoenix
+  generators will generate web files directly in your lib and test folders
+  since the application is assumed to be isolated to web specific functionality.
+  If `:context_app` is not set, the generators will place web related lib
+  and test files in a `web/` directory since the application is assumed
+  to be handling both web and domain specific functionality.
+  Example configuration:
+
+      config :my_app_web, :generators, context_app: :my_app
+
+  Alternatively, the `--context-app` option may be supplied to the generator:
+
+      mix phx.gen.live Sales User users --context-app warehouse
+
+  ## Web namespace
+
+  By default, the controller and view will be namespaced by the schema name.
+  You can customize the web module namespace by passing the `--web` flag with a
+  module name, for example:
+
+      mix phx.gen.live Sales User users --web Sales
+
+  Which would generate a LiveViews inside `lib/app_web/live/sales/user_live/` and a
+  view at `lib/app_web/views/sales/user_view.ex`.
+
+  ## Customising the context, schema, tables and migrations
+
+  In some cases, you may wish to bootstrap HTML templates, LiveViews,
+  and tests, but leave internal implementation of the context or schema
+  to yourself. You can use the `--no-context` and `--no-schema` flags
+  for file generation control.
+
+  You can also change the table name or configure the migrations to
+  use binary ids for primary keys, see `mix phx.gen.schema` for more
+  information.
