+> NOTE: As the previous version stated, it is better to follow the <a href="https://git.lolcat.ca/lolcat/4get/src/branch/master/docs/apache2.md">Apache2 guide</a> instead of the Nginx one.
 
-Create a file in `/etc/nginx/sites-avaliable/` called `4get.conf` or any name you want and put this into the file:

+1. Login as root.
-    access_log /dev/null;
+2. Upgrade your system:
-    error_log /dev/null;
+   * On Arch-based, run `pacman -Syu`.
-    # Change this if you have 4get in other folder.
+   * On Debian-based, run `apt update`, then `apt upgrade`.
+3. Install the following dependencies:
+   * `git`: So you can clone <a href="https://git.lolcat.ca/lolcat/4get">this</a> repository.
+   * `nginx`: So you can run Nginx.
+   * `php-fpm`: This is what allows Nginx to run *(and show)* PHP files.
+   * `php-imagick`, `imagemagick`: Image manipulation.
+   * `php-apcu`: Caching module.
+   * `php-curl`, `curl`:  Transferring data with URLs.
+   * `php-mbstring`: String utils.
+   * `certbot`, `certbot-nginx`: ACME client. Used to create SSL certificates.
+     * In Arch-based distributions:
+       * `pacman -S nginx certbot php-imagick certbot-nginx imagemagick curl php-apcu git`
+     * In Debian-based distributions:
+       * `apt install php-mbstring nginx certbot-nginx certbot php-imagick imagemagick php-curl curl php-apcu git`
+
+<div align=right>
+
+> IMPORTANT: `php-curl`, `php-mbstring` might be a Debian-only package, but this needs further fact checking.
+
+> IMPORTANT: `php-apcu` is known to not work on Artix[^1].

+4. `cd` to `/etc/nginx` and make the `conf.d/` directory if it doesn't exist:

+   ls -l conf.d/ # If ls shows conf.d, then it means it exists.
+   # If it does not, run:

+5. Make a file inside `conf.d/` called `4get.conf` and place the following content:

+    * The above is a very basic configuration and thus will need tweaking to your personal needs. It should still work as-is, though. A 'real world' example is present in [^2].
+    * After saving the file, check that the `nginx.conf` file inside the main directory includes files inside `conf.d/`:

+        types_hash_max_size 4096;
+        # ...
+      }
+      ```
+    * Now, test your configuration with `nginx -t`, if it says that everything is good, restart *(or start)* the Nginx daemon:
+      * This depends on the init manager, most distributions use `systemd`, but it's better practice to include most.
+      ```sh
+      # systemd
+      systemctl stop nginx
+      systemctl start nginxt
+      # or
+      systemctl restart nginx
 
-That is a very basic config so you will need to adapt it to your needs in case you have a more complicated nginx configuration. Anyways, you can see a real world example [here](https://git.zzls.xyz/Fijxu/etc-configs/src/branch/selfhost/nginx/sites-available/4get.zzls.xyz.conf)
+      # openrc
+      rc-service nginx stop
+      rc-service nginx start
+      # or
+      rc-service nginx restart
 
-After you save the file you will need to do a symlink of the `4get.conf` file to `/etc/nignx/sites-enabled/`, you can do it with this command: 
+      # runit
+      sv down nginx
+      sv up nginx
+      # or

-```
+      s6-rc -u change nginx
+      # or
+      s6-svc -r /run/service/nginx
 
-Now test the nginx config with `nginx -t`, if it says that everything is good, restart nginx using `systemctl restart nginx`
+      # dinit
+      dinitctl stop nginx
+      dinitctl start nginx
+      # or
+      dinitctl restart nginx
+      ```
+6. Clone the repository to `/var/www`:
+   * `git clone --depth 1 https://git.lolcat.ca/lolcat/4get 4get` - It clones the repository with the depth of one commit *(so it takes less time to download)* and saves the cloned repository as '4get'.

-Generate a certificate for the domain using:
+1. Generate a certificate for the domain you're using with:

+    ```sh
+    certbot --nginx --key-type ecdsa -d www.yourdomain.com -d yourdomain.com
+    ```
+2. After that, certbot will deploy the certificate automatically to your 4get conf file; It should be ready to use from there.
