 ## Description
 
 Plankton is a flexible and efficient library for handling n-gonal meshes. Plankton is written in C# and implements the [halfedge data structure][hds].  The structure of the library is loosely based on [Rhinocommon][rc]'s mesh classes and was originally created for use within C#/VB scripting components in [Grasshopper][gh].

 ## Features
 
 * **Flexible** – Plankton can represent n-gonal meshes. There is no restriction to the number of sides that a face can have.
-* **Fast** – Efficient adjacency queries (traversals) are provided by the underlying [halfedge data structure][hds].  These operations, such as finding the faces adjacent to a particular vertex, are *O(n)* where *n* is the number of elements returned.

 * **Robust** – Several [Euler operators][euler] have been implemented (such as edge-collapsing, and face-splitting) that allow the user to modify the topology of a mesh without worrying about the specifics of the data structure.
 * **Compatible** – Plankton can interface with the face-vertex mesh representation, making it straightforward to use alongside [Turtle].

 The easiest way to use Plankton is to download the latest [release][releases].  Both the core library, `plankton.dll`, and the Grasshopper assembly, `plankton.gha`, should be copied into Grasshopper's "libraries" folder (usually `%appdata%\Roaming\Grasshopper\Libraries\`).  Rhino will need to be restarted if it is already running and don't forget to **unblock** the assemblies!
 
-To use Plankton from a C#/VB scripting component in Grasshopper you'll need to reference the library in the script. Right-click on the component, choose "Manage Assemblies" and using the dialog box, select **both** of the assemblies.  See [here][scripting] for more information about writing scripts that use Plankton.
