 `samples.csv` contains sample attributions. All samples are available in `samples/` directory.
 
+## Snippets
+
+The main `battery.tidal` reflects the original composition, and includes 'initial states' of the various patterns used with notes on what should be changed and when. New patterns are prefaced with a comment like `-- @something` declaring its 'key' for reference.
+
+In the `snippets/` directory are [yasnippet](http://joaotavora.github.io/yasnippet/)-compatible snippet files reflecting these references, and additionally a `b1setup` snippet (which contains the project setup) and a `battery123` snippet that provides a convenient list of all project snippets.
+
+For easy loading and use in emacs Tidal, copy or symlink the snippets into a `haskell-mode` major group in one of your snippet folders.
