-## About 
+![Soapbox](https://soapbox.pub/blog/soapbox-fe-v1.2-release/soapbox-fe-1.2-screenshot.png)
 
-Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support ActivityPub. What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.
+**Soapbox** is a federated social media server with a focus on user experience.
+It is based on [Pleroma](https://pleroma.social/).
 
-Pleroma is written in Elixir and uses PostgresSQL for data storage. It's efficient enough to be ran on low-power devices like Raspberry Pi (though we wouldn't recommend storing the database on the internal SD card ;) but can scale well when ran on more powerful hardware (albeit only single-node for now).
+## Your social media server
 
-For clients it supports the [Mastodon client API](https://docs.joinmastodon.org/api/guidelines/) with Pleroma extensions (see the API section on <https://docs-develop.pleroma.social>).
+Soapbox empowers people to take control of their social media experience.
+Hosting your own server means that *you* get to decide the rules.
 
-- [Client Applications for Pleroma](https://docs-develop.pleroma.social/backend/clients/)
+Soapbox connects to over 4,000 other servers on the Fediverse.
+It is designed to spread your message far and wide, while being resilient to deplatforming.
 
 ## Installation
 
-### OTP releases (Recommended)
-If you are running Linux (glibc or musl) on x86/arm, the recommended way to install Pleroma is by using OTP releases. OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it. The installation instructions are available [here](https://docs-develop.pleroma.social/backend/installation/otp_en/).
+See [the installation guide](https://gitlab.com/soapbox-pub/soapbox/-/blob/develop/docs/installation/ubuntu_en.md).
 
-### From Source
-If your platform is not supported, or you just want to be able to edit the source code easily, you may install Pleroma from source.

-### Compilation Troubleshooting
-If you ever encounter compilation issues during the updating of Pleroma, you can try these commands and see if they fix things:
-
-- `mix deps.clean --all`
-- `mix local.rebar`
-- `mix local.hex`
-- `rm -r _build`
-
-If you are not developing Pleroma, it is better to use the OTP release, which comes with everything precompiled.

+# Installing Soapbox on Ubuntu
+
+We recommend installing Soapbox on a **dedicated VPS (virtual private server) running Ubuntu 20.04 LTS**.
+You should get your VPS up and running before starting this guide.
+
+Some popular VPS hosting providers include:
+
+- [DigitalOcean](https://m.do.co/c/84e2ff1e790f) <sup>[referral link]</sup> &mdash; easy to use
+- [Hetzner Cloud](https://www.hetzner.com/cloud) &mdash; cheap
+- [BuyVM](https://buyvm.net/) &mdash; supports free speech
+
+Expect to spend between **$10&ndash;15 USD/mo**, depending on the size of your community and how you choose to configure it.
+
+You should already have a **domain name** from a registrar like [Namecheap](https://www.namecheap.com/) or [Epik](https://www.epik.com/).
+Create an `A` record with your registrar pointing to the IP address of your VPS.
+
+## 1. Shelling in
+
+Once your VPS is running, you'll need to open a **terminal program** on your computer.
+This will allow you to remotely connect to the server so you can run commands and install Soapbox.
+
+![Screenshot_from_2021-04-28_14.06.37](https://gitlab.com/soapbox-pub/soapbox/uploads/1b4f956398736e2016d6d30b3d9567c6/Screenshot_from_2021-04-28_14.06.37.png)
+
+Linux and Mac users should have a terminal program pre-installed (it's just called **"Terminal"**), but Windows users may need to install [Cygwin](https://www.cygwin.com/) first.
+
+Once the terminal is open, connect to your server with the username and IP address provided by your VPS host.
+It will likely prompt for a password.
+
+```sh
+ssh root@123.456.789
+```
+
+If you see a screen that looks like this, you've succeeded:
+
+```

+root@gleasonator:~#
+```
+
+## 2. System setup
+
+Before installing Soapbox, we have to prepare the system.
+
+### 2.a. Install updates
+
+Usually a fresh VPS already has outdated software, so run the following commands to update it:
+
+```shell
+sudo apt update
+sudo apt upgrade
+```
+
+When prompted (`[Y/n]`) type `Y` and hit Enter.
+
+### 2.b. Install system dependencies
+
+Soapbox relies on some additional system software in order to function.
+Install them with the following command:
+
+```shell
+sudo apt install git build-essential postgresql postgresql-contrib cmake libmagic-dev imagemagick ffmpeg libimage-exiftool-perl nginx certbot
+```
+
+### 2.c. Install Elixir
+
+Soapbox uses the Elixir programming language (based on Erlang).
+Unfortunately the latest version is not included in Ubuntu by default, so we have to add a third-party repository before we can install it.
+
+To install the Elixir repository, use these commands:
+
+```shell
+wget -P /tmp/ https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb
+sudo dpkg -i /tmp/erlang-solutions_2.0_all.deb
+```
+
+Now we can install Elixir (and Erlang):
+
+```shell
+sudo apt update
+sudo apt install elixir erlang-dev erlang-nox
+```
+
+### 2.d. Create the Pleroma user
+
+For security reasons, it's best to run Soapbox as a separate user with limited access.
+
+We'll create this user and call it `pleroma`:
+
+```shell
+sudo useradd -r -s /bin/false -m -d /var/lib/pleroma -U pleroma
+```
+
+## 3. Install Soapbox
+
+Finally! It's time to install Soapbox itself.
+Let's get things up and running.
+
+### 3.a. Downloading the source code
+
+We'll need to create a folder to hold the Soapbox source code, then download it with git:
+
+```shell
+sudo mkdir -p /opt/pleroma
+sudo chown -R pleroma:pleroma /opt/pleroma
+sudo -Hu pleroma git clone -b stable https://gitlab.com/soapbox-pub/soapbox /opt/pleroma
+```
+
+### 3.b. Install Elixir dependencies
+
+First let's enter the Soapbox source code directory:
+
+```shell
+cd /opt/pleroma
+```
+
+Soapbox depends on third-party Elixir modules which need to be downloaded:
+
+```shell
+sudo -Hu pleroma mix deps.get
+```
+
+If it asks you to install `Hex`, answer `yes`:
+
+### 3.c. Generate the configuration
+
+It's time to preconfigure our instance.
+The following command will set up some basics such as your domain name.
+
+```sh
+sudo -Hu pleroma mix pleroma.instance gen
+```
+
+* Answer with `yes` if it asks you to install `rebar3`.
+
+* This may take some time, because parts of pleroma get compiled first.
+
+* After that it will ask you a few questions about your instance and generates a configuration file in `config/generated_config.exs`.
+
+Check if the configuration looks right.
+If so, rename it to `prod.secret.exs`:
+
+```shell
+sudo -Hu pleroma mv config/{generated_config.exs,prod.secret.exs}
+```
+
+### 3.d. Provision the database
+
+The previous section also created a file called `config/setup_db.psql`, which you can use to create the database:
+
+```shell
+sudo -Hu postgres psql -f config/setup_db.psql
+```
+
+Now run the database migration:
+
+```shell
+sudo -Hu pleroma MIX_ENV=prod mix ecto.migrate
+```
+
+### 3.e. Start Soapbox
+
+Copy the systemd service and enable it to start Soapbox:
+
+```shell
+sudo cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
+sudo systemctl enable --now pleroma.service
+```
+
+If you've made it this far, congrats!
+You're very close to being done.
+Your Soapbox server is running, and you just need to make it accessible to the outside world.
+
+## 4. Getting online
+
+The last step is to make your server accessible to the outside world.
+We'll achieve that by installing Nginx and enabling HTTPS support.
+
+### 4.a. HTTPS
+
+We'll use certbot to get an SSL certificate.
+
+First, shut off Nginx:
+
+```sh
+systemctl stop nginx
+```
+
+Now you can get the certificate:
+
+```shell
+sudo mkdir -p /var/lib/letsencrypt/
+sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --standalone
+```
+
+Replace `<your@emailaddress>` and `<yourdomain>` with real values.
+
+### 4.b. Nginx
+
+Copy the example nginx configuration and activate it:
+
+```shell
+sudo cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/sites-available/pleroma.nginx
+sudo ln -s /etc/nginx/sites-available/pleroma.nginx /etc/nginx/sites-enabled/pleroma.nginx
+```
+
+Before starting Nginx again, edit the configuration and change it to your needs (e.g. change servername, change cert paths)
+
+Enable and start nginx:
+
+```shell
+sudo systemctl enable --now nginx.service
+```
+
+🎉 Congrats, you're done!
+Check your site in a browser and it should be online.
+
+## 5. Post-installation
+
+Below are some additional steps you can take after you've finished installation.
+
+### Create your first user
+
+If your instance is up and running, you can create your first user with administrative rights with the following task:
+
+```shell
+sudo -Hu pleroma MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
+```
+
+### Renewing SSL
+
+If you need to renew the certificate in the future, uncomment the relevant location block in the nginx config and run:
+
+```shell
+sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --webroot -w /var/lib/letsencrypt/
+```
+
+## Questions
+
+If you have questions or run into trouble, please [create an issue](https://gitlab.com/soapbox-pub/soapbox/-/issues) on the Soapbox GitLab.
