+### Exporting articles
+
+By default, Paperoni exports to EPUB files but you can change to HTML by passing the `--export html` flag.
+
+```sh
+paperoni https://en.wikipedia.org/wiki/Pepperoni --export html
+```
+
+HTML exports allow you to read the articles as plain HTML documents on your browser but can also be used to convert to PDF as explained [here](#).
+
+When exporting to HTML, Paperoni will download the article's images to a folder named similar to the article. Therefore the folder structure would look like this for the command ran above:
+
+```
+.
+├── Pepperoni - Wikipedia
+│   ├── 1a9f886e9b58db72e0003a2cd52681d8.png
+│   ├── 216f8a4265a1ceb3f8cfba4c2f9057b1.jpeg
+│   ...
+└── Pepperoni - Wikipedia.html
+```
+
+If you would instead prefer to have the images inlined directly to the HTML export, pass the `inline-images` flag, i.e.:
+
+```sh
+paperoni https://en.wikipedia.org/wiki/Pepperoni --export html --inline-images
+```
+
+This is especially useful when exporting multiple links.
+
+**NOTE**: The inlining of images for HTML exports uses base64 encoding which is known to increase the overall size of images by about 25% to 33%.
+
+### Disabling CSS
+
+The `no-css` and `no-header-css` flags can be used to remove the default styling added by Paperoni. Refer to `--help` to see the usage of the flags.

 Alternatively, you can use the Calibre GUI to do the file conversion.
+
+### HTML to PDF
+
+The recommended approach is to use [Weasyprint](https://weasyprint.org/start/), a free and open-source tool that converts HTML documents to PDF. It is available on Linux, MacOS and Windows. Using the CLI, it can be done as follows:
+
+```sh
+paperoni https://en.wikipedia.org/wiki/Pepperoni --export html
+weasyprint "Pepperoni - Wikipedia.html" Pepperoni.pdf
+```
+
+Inlining images is not mandatory as Weasyprint will be able to find the files on its own.
+
+### Comparison of PDF conversion methods
+
+Either of the conversion methods is sufficient for most use cases. The main differences are listed below:
+| | EPUB to PDF | HTML to PDF |
+|----------------------|----------------------------|------------------|
+| Wrapping code blocks | Yes | No |
+| CSS customization | No | Yes |
+| Generated file size | Slightly larger | Slightly smaller |
+
+The difference in file size is due to the additional fonts added to the PDF file by `ebook-convert`.
