 ## Building
 
-NOTE: The process described here will change sooner than later.
-
-Turn uses the Indexer and Mast gems to simplify project building.
-
-The Indexer gem defines a strict structure for project metadata. Use the `index`
-command to build the `.index` file from the editable `Index.rb` source.
-The `.gemspec` file is written to get the information it needs from the `.index`
-file. To build a gem simply use `gem build .gemspec`.
-
-The `mast` command is used to keep an up-to-date `Manifest.txt` file. The gemspec
-uses this file to determine which files to include in the gem. Just use
-`mast -u` to update it. The top line in the Manifest.txt file determines it's
-contents.
