# Library setup

By now, you should have followed the
Installation instructions. You should have Hugo and Node installed, and a local copy of a forked version of Infusion. You should also have run `npm install` in the root of that codebase.

## “Cleaning” the content folder

Before you can start documenting patterns, there are a few things still to do in order to get set up. At the moment, your version of Infusion is a facsimile of the original, containing all this documentation content. We want to delete that content and replace it with some starter content. There’s a simple `clean` command for this.

If you are contributing to an existing Infusion library, do not run the following command. It will delete all of the patterns in that library. The `clean` command is just for libraries that you are starting from scratch.

    npm run clean

This will leave your `content` folder with just an `_index.md` file and a `patterns` folder containing a single demonstration pattern file. Find out more about these in
Library structure.

## The `setup` command

There’s another command, `setup`, which you need to run to create an initial build and make sure git is aware of the `/docs` folder it generates.

    npm run setup

## The config file

You’ll also want to name your library and configure one or two other things in the `config.toml` file that’s found at the root of your project. Here’s how that file looks:

    languageCode = "en-us"
    title = "Infusion"
    baseURL = "https://heydon.github.io/infusion/"
    theme = "infusion"

    [params]
      description = "Documentation for the **Infusion** pattern library builder. This documentation is constructed using the builder itself."
      codePenUser = "Heydon"

- title — This is the library’s name, like “Megacorp 5000 Pattern Library”. You don’t have to include the term “pattern library” if you don’t want to. For Infusion’s own version of Infusion, the `title` is, naturally, Infusion :-)
- baseURL — This is the root of the live site. Typically you will publish the site to Github Pages, so this should be the base URL for your Github Pages site.
- theme — This is the theme the library is using. Don’t change this from “infusion”.
- description — This is a short description of the library and comes under the logo. You can include markdown syntax here, like **Infusion** in the above example for making the name of the library bold.
- codePenUser — If you want to embed codePens in your pattern files, you need to supply a codePen username here.

## Including a logo

In the `images/static` folder, you’ll find a `logo.png` file. Replace this file with your own company or project logo. Currently, only the PNG format is supported.

Now that your logo’s in place, everything should be ready. Where next? You can learn about
Library structure to help you get writing, or find out how to serve the library locally and on Github Pages in
Serving.
