-A hard link is one file which exists in multiple locations.
-
-Each file has an ID, which is kept on the hard disk's partition.
-Each hard link has the same ID, because they are the same file.
-This ID is called the 'inode'.
-
-Create a file, and a hard link:
-
-```bash
-fortune > $file_1
-mkdir -p x/y/z/
-ln $file_1 x/y/z/$file_2
-```
-Have a long look at the file with the `-l` flag, and check the inode with `-i`:
-
-```bash
-ls -li $file_1 x/y/z/$file_2
-```
-
-Since they are the same file, you can make a change to one, and it changes both:
-
-```bash
-fortune | tee x/y/z/$file_2
-cat $file_1
-cat x/y/z/$file_2
-```
-
-# Danger Zone
-
-- hard links will not work on directories, only standard files and fifos.
-- `git` will destroy and remake files, so it will not respect hard links.
-- Files cannot have a hard link on another disk partition, because the inode is stored on each partition.

+Link from X to Y.
 
-There are two types:
+```bash
+ln -s X ../otherdir/Y
+```
+
+If you want a hard link, this will make a single file exist in two locations.
+If it is deleted in one location, it continues to exist in the other.
+
+```bash
+ln *X* *Y*
+```
+
+Both files must be on the same hard drive, as they have the same inode (check this with `ls -i file`).

-A soft link is a file which says how to go to another file.
-When a program encounters a soft link, it will make a  guess at whether it should ignore it, or try to get to that file.
-
-To make a soft link to a file in the current directory, linking is easy:
-
-```bash
-fortune > $file_1
-ln -s $file_1 $link_1
-```
-
-Now imagine your directory looks like this:
-
-```
-dir_0/
-├── dir_1
-│   └── file_1
-├── dir_2
-│   └── file_1
-├── file_1
-└── link_1
-
-```
-
-Inside `dir_1`, making a soft link to `dir_0/file_1` would mean putting the directions to that file:
-
-```bash
-cd dir_1
-ln -s ../file_1 link_1
-```
-
-The real content of the file is just '`../file_1`, so making it from another directory would mean writing exactly the same address to that file:
-
-```bash
-ln -s ../file_1 dir_2/link_2
-```
-
-Both symlinks are identical, except for the name.
-
-```
-dir_0/
-├── dir_1
-│   ├── file_1
-│   └── link_1   <-- This one points to ../file_1
-├── dir_2
-│   ├── file_1
-│   └── link_2   <-- This one points to ../file_1 as well.
-└── file_2
-
-```
-
-Since it's just an address, you can delete the original file, then make another.
-
-```bash
-rm file_1
-ls -l dir_1/
-fortune > file_1
-cat dir_2/link_2
-fortune | tee -a file_1
-cat dir_1/link_1
-```
-
-Last, let's make a link from `dir_2/link_2` to `dir_1/file_1` (this will delete the old link):
-
-```bash
-ln -s -f ../dir_1/file_1 dir_2/link_2
-cat dir_2/link_2
-```

-## `http` Setup
-
-In this example, the port used is `23231`, but it can be anything.
-Open `/var/lib/soft-serve/data/config.yaml` and make sure the `http` section looks like this:
-
-```
-# The HTTP server configuration.
-http:
-  # The address on which the HTTP server will listen.
-  listen_addr: ":23232"
-
-  # The path to the TLS private key.
-  tls_key_path: ""
-
-  # The path to the TLS certificate.
-  tls_cert_path: ""
-
-  # The public URL of the HTTP server.
-  # This is the address that will be used to clone repositories.
-  # Make sure to use https:// if you are using TLS.
-  public_url: "http://localhost:23232"
-
-```
-
-Restart the `soft-serve` service, then check it's working by cloning from localhost:
-
-```bash
-git clone http://localhost:23232/${some_repo}.git
-```
-
-## `https` Setup
-
-Put this file at `/etc/nginx/sites-enabled/$DOMAIN.tld`, then set up standard certificates with [nginx](../networking/website/nginx.md).
