 # Requirements
+
 Currently Opa uses https://polyfill.io/v3/polyfill.min.js?flags=gated for better support because your browser needs to support these three features:
+
 - https://caniuse.com/#search=es6
 - https://caniuse.com/#feat=flexbox
 - https://caniuse.com/#feat=intersectionobserver
 - https://caniuse.com/#feat=atob-btoa
 
+Also, your XMPP server must support MSM/RSM (for message archiving).

 # Getting Started
 
 The initial idea of Opa was to be a plug-n-play client to any XMPP server.

 ## Installation
+
 ### NodeJS (From Source)
+
 The installation with NodeJS will need you to install the package manager [Yarn](https://yarnpkg.com/pt-BR/). You can install Yarn on an NodeJS environment with this command:
+
 ```
 npm install yarn -g
 ```
+
 After installing Yarn you will need to clone the project into a folder. This folder will be where the Opa server will run from:
+
 ```
 git clone https://github.com/credija/opa.git
 ```
+
 After clonning the project you will need to navigate to this folder and run the command below to build and start Opa:
+
 ```
 yarn build && yarn start

 ### Docker
 
 The installation with Docker is very straightforward. You will, however, need to connect to your XMPP server. To do that you need to overwrite the /app/static/config/app-config.json (explanation of each option in the config file is in [Configuration](#configuration) section):
+
 ```
 docker run --name opa -d --restart=always \
   --publish 3000:3000 \
   --volume /opt/your-config.json:/app/static/config/app-config.json \

 Note: If you want to use a XMPP server in Docker we recommend our Openfire build which is available here: https://github.com/credija/openfire
 
 ## Configuration
 
 To connect to an XMPP server you will need to overwrite the [app-config.json](https://github.com/credija/opa/blob/master/static/config/app-config.json). The options are these:
+
 - **XMPP_SERVER_ADDRESS**: The address for the HTTP/S BOSH or WSS WebSocket connection.
 - **XMPP_SERVER_DOMAIN**: Your chat domain.
 - **APP_LOCALE**: The locale needs to be set in the format "language-country", like "en-us", "pt-br", etc since this value will be used to format date through the app.
 
 ## Internationalization
 
-Opa has a plug-n-play structure for locales, which are stored in /static/locales.
