+Deploying On Any Platform
+=========================
+
+To deploy Multinet on a platform other than Heroku, there are some generic
+steps that you can take. We offer these steps as a simple guide that will likely
+require some refinement for your specific deployment.
+
+We follow the 12 factor app paradigm as described `here <https://12factor.net/>`_.
+This should also inform your deployment strategy, and we recommend deploying each
+program of our stack on separate servers. There are also some tips for a
+monolithic deployment below, just in case that is your only option.
+
+ArangoDB
+--------
+
+Your ArangoDB instance should be installed to your server/vm and initialized with
+a **strong** ``root`` password. You're welcome to change the port here if that
+satisfies your security concerns. 
+
+Once you've set up your root user, connect to the ArangoDB instance using the
+default port (or the port you set), and create a user called ``readonly``. This
+user should also have a strong password. Once you've set this user up, you should
+go to their permissions and set read-write access to all databases by clicking
+access for the database ``*``.
+
+There may also be some additional configuration that you'll need to in order
+for the ``multinet-server`` instance to communicate with the database. This
+might include port forwarding and establishing firewall rules, but will differ
+on a case-by-case basis.
+
+``multinet-server``
+-------------------
+
+Make sure you have python3.7 and `pipenv <https://pipenv-fork.readthedocs.io/en/latest/install.html#installing-pipenv/>`_ installed. Then:
+
+1. Clone the repository: ``git clone https://github.com/multinet-app/multinet-server``.
+2. Move into the repository: ``cd multinet-server``.
+3. Copy the ``.env.default`` file: ``cp .env.default .env`` (or symlink it: ``ln
+   -s .env.default .env``).
+4. Create :ref:`OAuth2 Credentials` and make sure to copy them to your .env file.
+5. Set ALLOWED_ORIGINS to the address for your ``multinet-client`` instance,
+   including the protocol (e.g. https://multinet.app, yours will be different)
+6. Set your ARANGO_PASSWORD to the ``root`` password for ArangoDB, and your 
+   ARANGO_READONLY_PASSWORD to the password you created for the ``readonly`` user.
+7. Install the Python dependencies: ``pipenv install``.
+8. Run the server application in production mode with:
+   ``pipenv run gunicorn multinet.app:app``. **NOTE:** This uses gunicorn's
+   default settings, where the app is hosted on http://127.0.0.1:8000. There are
+   cases where a socket would be best (e.g. when using reverse proxies, see 
+   `below <#using-reverse-proxies>`_). In that case, run the same command with
+   an additional flag, for example: ``pipenv run gunicorn --bind unix:./socket.sock multinet.app:app``.
+   The socket will be located in the ``multinet-server`` directory.
+
+``multinet-client``
+-------------------
+
+1. Clone the repository: ``git clone https://github.com/multinet-app/multinet-client``.
+2. Move into the repository: ``cd multinet-client``.
+3. Install the project dependencies: ``yarn install``.
+4. Copy .env.default to .env and configure the ``VUE_APP_MULTINET_HOST``.
+5. Build the production app: ``yarn build``.
+
+At this point, you have a few options for how to proceed. The most recommended
+way to continue is to serve these files using a production webserver such as
+`nginx <https://www.nginx.com/>`_ or `apache webserver <https://httpd.apache.org/>`_.
+See the docs for these projects for details on how to do that.
+
+Handling DNS
+------------
+
+All of these services can be deployed onto separate servers/vms. If this is how
+you want to deploy them, and you have a domain, you can assign a subdomain (through
+your DNS provider) for each program in the stack. For a given example domain
+``domain.com``, you could organize the services as follows:
+
+* domain.com and www.domain.com for the ``multinet-client`` application
+* db.domain.com for the ArangoDB instance
+* api.domain.com for the ``multinet-server`` application
+
+There may be some additional apps that you can host on the same domain. For
+example, we host MultiLink and MultiMatrix on subdomains of our main domain.
+
+Using Reverse Proxies
+---------------------
+
+If you do decide to deploy these on a monolithic server, with all the apps
+together, you can't use the DNS method from above. Instead, you'll have to run
+a reverse proxy using a program such as `nginx <https://www.nginx.com/>`_,
+or `apache webserver <https://httpd.apache.org/>`_.
+
+Here's an example of an nginx.conf file that you might use. Note the different
+server_name in each server block::
+
+   user  nginx;
+   worker_processes 1;
+   error_log  /var/log/nginx/error.log warn;
+   pid        /var/run/nginx.pid;
+   events {
+      worker_connections 1024;
+   }
+   http {
+      include       /etc/nginx/mime.types;
+      default_type  application/octet-stream;
+
+      root /home/ubuntu/multinet-client/dist;
+      index index.html;
+
+      server {
+         listen 80 default_server;
+         server_name _;
+         return 301 https://$server_name$request_uri;
+      }
+
+      server {
+         listen 443 ssl;
+         server_name api.domain.com;
+         ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
+         ssl_ciphers         HIGH:!aNULL:!MD5;
+
+         ssl_certificate     /etc/letsencrypt/live/.../fullchain.pem;
+         ssl_certificate_key /etc/letsencrypt/live/.../key.key;
+
+         location / {
+               include uwsgi_params;
+               uwsgi_pass unix:///home/ubuntu/multinet-server/socket.sock;
+               uwsgi_read_timeout 7200s;
+               uwsgi_send_timeout 7200s;
+         }
+      }
+
+      server {
+         listen 443 ssl;
+         server_name www.domain.com domain.com;
+         ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
+         ssl_ciphers         HIGH:!aNULL:!MD5;

+         ssl_certificate     /etc/letsencrypt/live/.../fullchain.pem;
+         ssl_certificate_key /etc/letsencrypt/live/.../key.key;

+         location / {
+            try_files $uri $uri/ =404;
+        }
+      }
+   }
