-## Installing Pleroma
+## Docs
 
-- Clone this repository
+coming soon tm
-- Copy `.env.dist` to `.env`
-- Edit `.env` (see "Configuring Pleroma" section below)
-- Run `./pleroma build` and `./pleroma start`
-- Profit!
-
-## Updating Pleroma
-
-Just run `./pleroma build` again and `./pleroma start` afterwards.
-
-You don't need to shutdown pleroma while compiling the new release.
-
-Every time you run `./pleroma build` the script will fetch all upstream changes and checkout `PLEROMA_VERSION`.
-This means that setting `PLEROMA_VERSION` to a branch enables rolling-release updates while setting
-it to a tag or commit-hash pins the version.
-
-## Maintaining Pleroma
-
-Pleroma maintenance is usually done with premade mix tasks.<br>
-You can run these tasks using `./pleroma mix [task] [arguments...]`.<br>
-If you need to fix some bigger issues you can also spawn a shell using `./pleroma enter`.
-
-## Customizing Pleroma
-
-Just add your customizations (and their folder structure) to `custom.d`.<br>
-They will be mounted and symlinked into the right place when the container starts.<br>
-You can even replace/patch pleroma's code with this, because the project is recompiled at startup.<br>
-
-In general: Prepending `custom.d/` to pleroma's customization guides should work all the time.<br>
-Check them out in the [official pleroma wiki](https://git.pleroma.social/pleroma/pleroma/wikis/home).
-
-For example: A custom thumbnail now goes into `custom.d/priv/static/instance/thumbnail.jpeg` instead of `priv/static/instance/thumbnail.jpeg`.
-
-Note: Since `custom.d` needs to be accessible at runtime by the pleroma process, the container will automatically chown these files to `$UID:$GID` from your `.env` file.
-
-## Configuring Pleroma
-
-pleroma-docker tries to stay out of your way as much as possible while providing
-a good experience for both you and your users. It thus supports multiple
-"operation modes" and quite some config variables which you can mix and match.
-
-This guide will explain some of the tricky `.env` file parts as detailed as possible (but you should still read the comments in there).
-
-Since this setup [injects code](https://glitch.sh/sn0w/pleroma-docker/blob/master/docker-config.exs) into pleroma that moves it's configuration into the environment (ref ["The Twelve-Factor App"](https://12factor.net/)),
-the built image is 100% reusable and can be shared/replicated across multiple hosts.
-To do that just run `./pleroma build` as usual and then tag your image to whatever you want.
-Just make sure to start the replicated container with `env_file:` or all required `-e` pairs.
-
-#### Storing Data
-
-Currently all data is stored in subfolders of `DOCKER_DATADIR` which will be bind-mounted into the container by docker.
-
-We'll evaluate named volumes as an option in the future but they're currently not supported.
-
-#### Database (`SCRIPT_DEPLOY_POSTGRES`)
-
-Values: `true` / `false`
-
-By default pleroma-docker deploys a postgresql container and links it to pleroma's container as a zero-config data store. If you already have a postgres database or want to host postgres on a physically different machine set this value to `false`. Make sure to set the `POSTGRES_*` variables when doing that.
-
-#### Reverse Proxy (`SCRIPT_USE_PROXY`)
-
-Values: `traefik` / `nginx` / `manual`
-
-Pleroma is usually run behind a reverse-proxy.
-Pleroma-docker gives you multiple options here.
-
-##### Traefik
-
-In traefik-mode we will generate a pleroma container with traefik labels.
-These will be picked up at runtime to dynamically create a reverse-proxy
-configuration. This should 'just work' if `watch=true` and `exposedByDefault=false` are set in the `[docker]` section of your `traefik.conf`. SSL will also 'just work' once you add a matching `[[acme.domains]]` entry.
-
-##### NGINX
-
-In nginx-mode we will generate a bare nginx container that is linked to the
-pleroma container. The nginx container is absolutely unmodified and expects to
-be configured by you. The nginx file in [Pleroma's Repository](https://git.pleroma.social/pleroma/pleroma/blob/develop/installation/pleroma.nginx) is a good starting point.
-
-We will mount your configs like this:
-```
-custom.d/server.nginx -> /etc/nginx/nginx.conf
-custom.d/vhost.nginx -> /etc/nginx/conf.d/pleroma.conf
-```
-
-To reach your pleroma container from inside nginx use `proxy_pass http://pleroma:4000;`.
-
-Set `SCRIPT_PORT_HTTP` and `SCRIPT_PORT_HTTPS` to the ports you want to listen on.
-Specify the ip to bind to in `SCRIPT_BIND_IP`. These values are required.
-
-The container only listens on `SCRIPT_PORT_HTTPS` if `SCRIPT_ENABLE_SSL` is `true`.
-
-##### Apache / httpd
-
-Just like nginx-mode this starts an unmodified apache server that expects to be
-configured by you. Again [Pleroma's Config](https://git.pleroma.social/pleroma/pleroma/blob/develop/installation/pleroma-apache.conf) is a good starting point.
-
-We will mount your configs like this:
-```
-custom.d/server.httpd -> /usr/local/apache2/conf/httpd.conf
-custom.d/vhost.httpd -> /usr/local/apache2/conf/extra/httpd-vhosts.conf
-```
-
-To reach your pleroma container from inside apache use `ProxyPass [loc] http://pleroma:4000/`.
-
-Again setting `SCRIPT_PORT_HTTP`, `SCRIPT_PORT_HTTPS` and `SCRIPT_BIND_IP` is required.
-
-The container only listens on `SCRIPT_PORT_HTTPS` if `SCRIPT_ENABLE_SSL` is `true`.
-
-##### Manual
-
-In manual mode we do not create any reverse proxy for you.
-You'll have to figure something out on your own.
-
-This mode also doesn't bind to any IP or port.
-You'll have to forward something to the container's IP.
-
-#### SSL (`SCRIPT_ENABLE_SSL`)
-
-Values: `true` / `false`
-
-If you want to use SSL with your Apache or NGINX containers you'll need a
-certificate. Certificates need to be placed into `custom.d` and will be
-bind-mounted into the server's container at runtime.
-
-We will mount your certs like this:
-```
-custom.d/ssl.crt -> /ssl/ssl.crt
-custom.d/ssl.key -> /ssl/ssl.key
-```
-
-You can reference them in Apache like this:
-```apache
-<VirtualHost *:443>
-    SSLEngine on
-    SSLCertificateFile "/ssl/ssl.crt"
-    SSLCertificateKeyFile "/ssl/ssl.key"
-</VirtualHost>
-```
-
-And in NGINX like this:
-```nginx
-listen 443 ssl;
-ssl_certificate     /ssl/ssl.crt;
-ssl_certificate_key /ssl/ssl.key;
-```
-
-In traefik-mode and manual-mode these files and the `SCRIPT_ENABLE_SSL` value are ignored.
