# How to create an eBook from Markdown using Ibis?

# Introduction

A few months ago I wrote an [open-source eBook on how to get started with Bash Scripting](https://github.com/bobbyiliev/introduction-to-bash-scripting). 

This is when I came across a tool called [Ibis](https://github.com/themsaid/ibis) created by [Mohamed Said](https://twitter.com/themsaid) who is a Developer at Laravel.

Ibis allows you to generate an awesome PDF for your eBook, and you can just use markdown!

In this tutorial, I will show you how to get started with Ibis and write that eBook that you have always been planning to write!

# Prerequisites

You need to have Composer installed, if you don't have it yet, you can follow the steps here:

[How to install Composer](https://devdojo.com/tnylea/composer-why-what-and-how)

# Installation

In order to install Ibis, all that you need to do is run the following `composer` command:

```
composer global require themsaid/ibis
```

After the installation, you can test if the `ibis` command is available with the following:

```
ibis -V
```

Once you are sure that you have the Ibis command line tool installed, you can instantiate a new project with the following command:

```
ibis init
```

> Note: Make sure to run the command in an empty directory where you would store your Markdown files later on

The init command will generate the following files:

```
/assets
/assets/fonts
/assets/cover.jpg
/assets/theme-light.html
/assets/theme-dark.html
/content
/ibis.php
```

You can modify the `/assets/theme-light.html` and the `/assets/theme-dark.html` to change any of the styles for the eBook. For example, I like to increase the size of the text and the line spacing a little bit.

# Configuration

In order to configure `ibis` all that you need to do is change the values in the `ibis.php` file.

The main settings would be:

* `title`: The title of your eBook
* `author`: Your anme
* `sample`: Page ranges to be used with the sample command
* `sample_notice`: A notice printed at the final page of a generated sample

# Creating a cover photo

There is an awesome tool that you could use for free to generate your cover photo:

* [Canva](https://www.canva.com/join/determined-cork-learn)

If you ever need to create a graphic, poster, invitation, logo, presentation – or anything that looks good — give Canva a go!

To change the cover photo, just substitute the default `/assets/cover.jpg` with your image!

# Markdown files

With the above, you can then start writing your eBook! The content would be stored in the `content` folder where you will have to add your Markdown files.

Ibis would read all of the `.md` files in the `content` folder and would use all `h1` titles as the name of the chapters.

If you are not familiar with Markdown, make sure to check out this guide [here](https://www.digitalocean.com/community/tutorials/digitalocean-s-technical-writing-guidelines).

# Building the PDF

Once you have your content ready, in order to build the PDF of your eBook, just use the following commands

* Light mode

```
ibis build
```

* Dark mode

```
ibis build dark
```

If you want to generate a sample of your eBook use the following commands:

* Light mode sample:
```
ibis sample
```

* Dark mode sample:
```
ibis sample dark
```

Once you run the command, it will generate your PDF and store them in the `export` folder.

The output that you will see would look like this:

```
==> Preparing Export Directory ...
==> Parsing Markdown ...
==> Adding Book Cover ...
==> Building PDF ...
==> Writing PDF To Disk ...

✨✨ 34 PDF pages ✨✨

Book Built Successfully!
```
