+# I have a penchant for setting up all my projects so they work the same.
+
+I like to do these things in all my projects:
+
+* Have all my tests run before committing. I don't like buying ice cream for the team on test failures.
+* If I'm developing gems alongside this project, I use a `Gemfile.erb` to get around the "one gem, one source" issue in
+  current versions of Bundler.
+* If I'm moving to different machines or (heaven forbid!) having other developers work on the project, I want to make
+  getting all those local gems as easy as possible.
+
+This gem makes that easier!
+
+## What's it do?
+
+Installs a bunch of scripts into the `scripts` directory of your project:
+
+* `gemfile` which switches between `Gemfile.erb` environments
+* `install-git-hooks` which will do just what it says
+* `hooks/pre-commit`, one of the hooks the prior script installs
+* `initialize-environment`, which bootstraps your locak environment so you can get up and running
+
+## Gemfile.erb?!
+
+Yeah, it's a `Gemfile` with ERB in it:
+
+``` ruby
+<% if env == "local" %>
+  gem 'guard', :path => '../guard'
+<% else %>
+  gem 'guard', :git => 'git://github.com/johnbintz/guard.git'
+<% end %>
+
+Use `script/gemfile local` to get at the local ones, and `script/gemfile remote` (or anything, really) to get at the remote ones.
+It then runs `bundle install`.
+
+## git hook?!
+
+It runs `script/gemfile remote` then runs `bundle exec rake`. Make sure your default Rake task for the project runs your
+tests and performs any other magic necessary before each commit.
+
+## How?!
+
+* `gem install penchant`
+* `cd` to your project directory
+* `penchant install` (can do `--dir=WHEREVER`, too)
