+Papeer is a tool that lets you scrape content from the internet. It can scrape any web page, keeping only relevant content (formatted text and images) and removing ads and menus. You can export the content to Markdown, EPUB or MOBI files.

 ```

+# Examples
+
+## Grab a single page
+
+The `get` command lets you retrieve the content of a web page.
+
+```sh
+papeer get https://www.eff.org/cyberspace-independence
+# A Declaration of the Independence of Cyberspace
+# ===============================================
+
+# Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather...
+```
+
+## Grab several pages (recursive mode)
+
+The `recursive` option lets you extract the table of content of a website, then scrape the content of each one of its pages.
+
+### Display table of content
+
+Before trying the `recursive` option, it is a good idea to use the `ls` option, which lets you vizualize the content that will be retrieved. You can use several options to customize the table of content extraction, such as `selector`, `limit`, `offset` and `include`. Type `papeer help` for more information about those options.
+
+```sh
+papeer ls https://news.ycombinator.com/ --limit=5
+#  #  NAME                                                      URL

+#  2  A molten salt storage solution using sodium hydroxide     https://sifted.eu/articles/salt-energy-storage-seaborg-hyme/

+```
+
+### Scrape time
+
+Once you are satisfied with the table of content listed by the `ls` command, you can actually scrape the content of those pages. You can use the same options that you specified for the `ls` command. In recursive mode, you also have the possibility to use `delay` and `threads` options.
+
+```sh
+papeer get https://news.ycombinator.com/ --recursive --delay=500 --limit=5 --format=md
