+「 noTitleBar Terminal.app 」
+=================================
+
+Simple SIMBL plugin that removes the Titlebar (and Toolbar) from Terminal.app.
+
+Why and how
+-----------
+
+I've always envied Linux for the great window managers that the community
+produces. Some nice tools to mimic that behaviour are finally surfacing on OS X
+like [Hammerspoon][1] and [Kwm][2]. Many setups you see around use iTerm without
+the title bar, and since I thought it was pretty cool I decided to add the same
+option in Terminal.app
+The basic change is removing the NSTitledWindowMask during the window creation,
+the other hooked functions are needed to keep all Terminal features working.
+
+Download
+--------
+
+An already compiled bundle is available:
+
+[https://github.com/cHoco/noTitleBar-Terminal/releases]
+(https://github.com/cHoco/noTitleBar-Terminal/releases)
+
+Development
+-----------
+
+Download the development repository using Git:
+
+    git clone --recursive git://github.com/cHoco/noTitleBar-Terminal.git
+
+Run `make` to compile the plugin, and `make install` to install it into your
+home directory's SIMBL plugins folder.
