# Using Athena
-For this series of tutorials, we’re going to assume that you’re familiar with the basics of how to use the command line.
+**Intended Purpose:**
+
+* This article will help you answer the question “how can I have a website with an MIT domain”?
+* The website you’re making is static (otherwise [scripts](scripts.mit.edu) might be a better option!)
+* To be below the level of [afs-and-you](https://sipb.mit.edu/doc/afs-and-you/)
+
+**Prerequisites:**
+
+* Familiarity with using a terminal (experimented with basic commands like cd, ls, mkdir, etc.)

## Connecting to Athena
-The use of SSH (Secure Shell) allows a computer to remotely login into another computer/server, while making use of adequate security features. Thankfully, most operating systems have an SSH program already built in and no additional installs are needed on your machine. You can SSH into Athena by following these steps.

-**Note:** If your computer does not have `ssh`, you could also use shellinabox, an online terminal for using Athena that can be found [here](https://athena.dialup.mit.edu/). It’s not ideal, though, as it will log you off if you’re idle for a few minutes. (Which is probably not what you want when you’re following a guide like this.)

## Serving a website from AFS
-Now that you’re in Athena, you can access the files in AFS. Right now, you are in your home directory for AFS. There are several subdirectories in your home directory, but the important one to focus on right now is `~/www`.
+Now that you’re in Athena, you can access the files in MIT’S AFS. Right now, you are in your home directory for MIT’s AFS. There are several subdirectories in your home directory, but the important one to focus on right now is `~/www`.
-Files in your `~/www` directory are available on the internet through a URL, and more specifically of the form factor `https://web.mit.edu/aphacker/www/`. If you go to that URL right now though, you won’t see anything (besides a error). We can change that by making a small web page under that directory.
+Files in your `~/www` directory are available on the internet through a URL, specifically via the form factor of `https://web.mit.edu/aphacker/www/`. If you go to that URL right now though, you won’t see anything (besides an error). We can change that by populating that directory with the content that makes up a small web page.
First, `cd` into the `www` directory.
```
-aphacker@scrubbing-bubbles:~$ cd www
+aphacker@scrubbing-bubbles:~$ cd www
aphacker@scrubbing-bubbles:~/www$

```

```
-This should bring up a screen with the current contents of `index.html`, which you can now edit. You can read more about how to use nano elsewhere, but for now, it’s enough to know that pressing `<CTRL-O>` and then Enter will save the file, and `<CTRL-X>` will exit you from nano.

## Using SCP
-Editing a file through a remote shell isn’t the best way of making a file, however. A program called SCP (Secure Copy), which is bundled with SSH, allows copying files from your computer to AFS.
+If you feel unready to strictly edit files via the remote shell, using a package called SCP (Secure Copy), which is bundled with SSH, might be of interest. It allows you to copy files from your computer to AFS and vice-versa.
To copy a file from your computer to AFS, open your terminal and enter a command like
This will copy a file called `file.txt` to your home directory in AFS. You’ll have to do two-factor authentication with Duo, similar to SSH.
-You can [read the documentation](https://linux.die.net/man/1/scp) for more information about how to use SCP.
+You can read SCP’s man page (on the terminal via `man scp` or online at [man7](https://man7.org/linux/man-pages/man1/scp.1.html)) or other reference sheets (like [tldr-pages](https://tldr.ostera.io/scp) for more information about how to use SCP.

+1. In your machine’s VSC, install the [“official” ssh extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh)
+2. SSH into Athena and use your text editor to edit into `~\.bashrc`. Then, append this command at the end of the file (in a new line): `find ~/.vscode-server/ -name 'vscode-remote-lock.{kerberos}.*' -delete`. Here, you replace `{kerberos}` with your kerberos.
+3. Follow the extension’s steps for establishing a SSH connection.
