# Multi-page website
In this guide, you will learn how to host a website with multiple pages and external assets on IPFS. This tutorial is the second in a series of tutorials aimed at teaching web developers how to build websites and applications using IPFS. You don't need to have completed the previous tutorial to understand what's going on here, but if you're new to the IPFS ecosystem, it's a good idea to follow through the single page website guide before you start this one. It will give you a solid foundation to work off.
# Prerequisites
If you followed the previous tutorial, you would already have the IPFS Desktop application installed. If not, you can grab it from the IPFS Shipyard (opens new window).
# Project set up
Before we dig into IPFS, let's first create the files we'll need for this mini-project.
- Create a folder called
multi-page-first-step. - Within this new folder, create a file called
index.htmland paste in the following code. We'll continue using the Random Planet Facts (opens new window) website from the previous tutorial, with an added link to an About page:

<h1>Random Planet Facts</h1>
<p>
This website gives you random facts about the <i>planets</i> our solar
system! Refresh the homepage to see a new fact!

Add your name to the
Created by ___.line. If everyone reading this tutorial just copies and pastes the same code, then everyone will get the exact same CID! While there's nothing wrong with this, it's more fun to use a CID that is unique to your project.Finally, download this image and save it in the folder as
moon-logo.png:
You should now have a folder that looks something like this:
multi-page-first-step/
├── about.html
├── index.html
└── moon-logo.png
# Add files to IPFS
Now that you've got the project ready, we can add things to IPFS using the IPFS Desktop application. Instead of adding the files individually, we can add the whole project folder, and the IPFS Desktop app will take care of the rest for us!
Open the IPFS Desktop application and select Add > Folder.
Select the
multi-page-websitefolder. Once it's loaded, you should be able to see the folder within the application:
Click the triple dot menu to the right and select Share link.
Click Copy and paste the link in a browser. You should be able to see your website with the logo!
Try clicking the link to the about page. You should be able to browse between the pages with no problem.
# Publish to IPNS
This step is optional
You don't have to complete this section. However, it offers some valuable insight into how IPNS and IPFS work together.
Using CIDs to get content is great; it means that the user always gets the content that they want. But what if the user doesn't know what they're looking for and just wants the latest version of that content? This is where IPNS comes in handy.
Instead of sharing the CID of your website, you publish the root CID of your website to IPNS and then share the key you get from IPNS.
Open a terminal window, and navigate to where your multi-page project is saved:
cd ~/Code/random-planet-factsDouble check that this project has been added to IPFS by running
ipfs add -r .:ipfs add -r . > added QmP4KNjSaVCR3jTxi8nsMq3DDqGyVUXyc5vfij31J3B3vr multi-page-first-step/about.html > added QmYp2jy5t7knzwhkqPJ68amuAqLYJ3DG5vvxgJW6bFdQwN multi-page-first-step/index.html > added QmW8U3NEHx3p73Nj9645sGnGa8XzR43rQh3Kd52UKncWMo multi-page-first-step/moon-logo.png > added QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRR multi-page-first-step > 12.65 KiB / 12.65 KiB [=====================================================] 100.00%Copy the last CID
QmchJPQN...from the output of theipfs addcommand.Publish your project to IPNS using
ipfs name publish /ipfs/QMchJPQN.... ReplaceQMchJPQN...with the CID you got in the last step:ipfs name publish /ipfs/QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRR > Published to k51qzi5uqu5dh9gnl66grpnpuhj245ha1xq9ajtmuf7swe847zovdg1t9a0xiz: /ipfs/QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRRThe
k51qzi...is your IPFS installation's key! This is what you can use to point people to your content.You should now be able to view your project by going to
https://gateway.ipfs.io/ipns/k51qzi.... Replacek51qzi...with the output from the previous step.Whenever you make any changes to your project, simply re-add your content to IPFS and publish it to IPNS:
ipfs add -r . > ... > added QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRR multi-page-first-step 12.65 KiB / 12.65 KiB [=====================================================] 100.00% ipfs name publish QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRR > Published to k51qzi5uqu5dh9gnl66grpnpuhj245ha1xq9ajtmuf7swe847zovdg1t9a0xiz: /ipfs/QmchJPQNLE5EUSYTzfzUsNFyPozXyANiZHFDSFKWdLNdRRNow, just head back to the
https://gateway.ipfs.io/ipns/k51qzi...link to view your updates!
This is just the tip of the iceberg when it comes to IPNS. Check out the IPNS page to learn more →
