+# Process Inkscape files and create sets of cards for board games
+
+Not much in the way of docs yet. You'll need `inkscape`, `convert`, `montage`, and `gs` in your `PATH`.
+
+Create a `Cardfile` in your working directory. It should look
+something like this:
+
+``` ruby
+@session.configure do |c|
+  c.svg_source = "template/template.svg"
+  c.svg_merged_target = "template/output.svg"
+
+  c.png_export_width = 825
+  c.pdf_card_size = "750x1050"
+  c.pdf_dpi = 300
+
+  c.individual_files_path = "template/output/card_%02d.svg"
+  c.png_files_path = "template/png/card_%02d.png"
+
+  c.pdf_target = "merged.pdf"
+end
+
+@session.process do
+  require 'google_drive'
+  require 'virtus'
+  require 'active_support/inflector'
+
+  require './card_definitions.rb'
+
+  CardDefinitions.processed.each do |card|
+    @session.with_new_target do |target|
+      datum = card.to_svggvs
+
+      # #active_layers indicates what sublayers within the "Source" layer of
+      # the Inkscape document should be toggled as visible. All others are hidden.
+      target.active_layers = datum[:active]
+
+      # Any text with {% liquid_like_tags %} will have those tags replaced with the
+      # values within the hash passed in.
+      target.replacements = datum[:replacements]
+    end
+  end
+end
+```
+
+You can also have a `.cardrc` file which is run before loading the `Cardfile`.
+
+Process your cards with `svggvs`:
+
+* `svggvs merged_file`: Create a big SVG file with al cards as layers
+* `svggvs svgs`: Write out individual SVG files
+* `svggvs pngs`: Write out PNG files after writing out the SVG files
+* `svggvs pdf`: Write out the merged PnP PDF file
+
+You can also pass in `--cardfile <new file>` to load a different cardfile, say for
+card backs.
