-# Tilt::PDF::Rails
+# Tilt::PDF
 
-Integrates Tilt::PDF into Rails ActionView
+Integrates PDF generation into a Tilt flow for maxxed out ease of use.
 
-See [Tilt::PDF](https://github.com/lloeki/tilt-pdf) for details about the templates themselves.
+Contrary to other solutions, all files will be rendered locally without relying
+on a web server. It follows that even if used in a web server, no concurrent
+requests are being made to render assets.
 
-## Usage
+## Dependencies
+
+This gem depends on PDFKit, which in turn requires `wkhtmltopdf`. It is
+recommended to use the statically compiled version of the latter, as it is
+built against a patched QT that supports more features.
+
+## Usage as a Tilt template
+
+Add `tilt-pdf` to your Gemfile. Also add any template engine you may optionally
+want, such as `less` or `slim`.
+
+A `foo` template is currently threefold:
+
+- `foo.rpdf`: this file is a YAML file containing options pertaining to the PDF
+  generation process, such as page size, orientation, metadata, support files,
+  headers and footers. Some options are passed as is to PDFKit, and
+  subsequently to `wkhtmltopdf`.
+- `foo.html`: this document can be written in any template language you need
+  (such as ERB or Slim), and the Tilt template resolution system via extension
+  chaining will apply. Tilt will pass the render block to be yielded to this
+  document.
+- `foo.css`: this stylesheet can be written in any template language you need
+  (such as Sass or Less), and the Tilt template resolution system via extension
+  chaining will apply. Tilt will *not* pass the block to be yielded to this
+  template.
+
+The three files must currently be stored in the *same* directory.
+
+Rendering is done the usual Tilt way:
 
 ```ruby
-gem 'tilt-pdf-rails'
+require 'tilt-pdf'
+
+pdf = Tilt.new('foo.rpdf').render()
 ```
 
-Have a `FooController` `respond_to :pdf` and `render some_view` as usual.
+## The rpdf file
 
-Put your `some_view` template files either *together* in the relevant
-`app/views/foo` view directory, or use absolute paths using application/engine
-root.
+This file contains options. If empty, it is made to 'just work' as
+summplemental files will be looked up according to its basename.
 
-Work is in progress to enable better integration with Rails file layout (notably assets).
+- `main`: document body, overriding the default derived from the basename.
+- `footer` and `header`: html that will get used for (surprise!) header and
+  footers.
+- `stylesheets`: list of stylesheets to include (used for all html, incl.
+  headers/footers). Defaults to one file from the basename.
+- `javascripts`: list of javascripts to include (used for all html, incl.
+  headers/footers). Defaults to one file from the basename.
+- `pdfkit`: While a few PDFKit options are made available at the toplevel for
+  convenience, this key passes all options as-is to PDFKit.
+
+Example:
+
+```
+title: Foorever young
+page-size: A4
+orientation: landscape
+grayscale: true
+margin-left: 0
+margin-right: 0
+margin-top: 0
+margin-bottom: 0
+pdfkit:
+    print-media-type: true
+main: foorever_young.html.slim
+stylesheets:
+  - novel.css.less
+  - common.css
+javascripts:
+  - page_numbering.js.coffee
+footer: footer.html.slim
+```
+
+Filenames can be relative or absolute. When relative, they will be evaluated
+as based from the rpdf file.
+
+## Rails and ActionView integration
+
+Require `tilt/pdf/rails` if you want to set up and register `tilt-pdf` as an
+ActionView template handler. You can do it in an initializer, or straight from
+the Gemfile:
+
+```ruby
+gem 'tilt-pdf', require: 'tilt/pdf/rails'
+```
+
+Put your three template files *together* in the relevant `app/views/foo` view
+directory, or use absolute paths using application/engine root. Work is in
+progress to enable better integration with Rails file layout.
