-Install with Docker
-------------------
+# Install with Docker
+
+A preconfigured Docker image is available, including OCR and media conversion tools, listening on port 8080. If no PostgreSQL config is provided, the database is an embedded H2 database. The H2 embedded database should only be used for testing. For production usage use the provided PostgreSQL configuration (check the Docker Compose example)

-From a Docker host, run this command to download and install Teedy. The server will run on <http://[your-docker-host-ip]:8100>.
 **The default admin password is "admin". Don't forget to change it before going to production.**

-    docker run --rm --name teedy_latest -d -e DOCS_BASE_URL='http://[your-docker-host-ip]:8100' -p 8100:8080 -v teedy_latest:/data sismics/docs:latest
-  <img src="http://www.newdesignfile.com/postpic/2011/01/green-info-icon_206509.png" width="16px" height="16px">  **Note:** You will need to change [your-docker-host-ip] with the IP address or FQDN of your docker host e.g.
-  
-  FQDN: http://docs.mycompany.com  
-  IP: http://192.168.100.10
+- Master branch, can be unstable. Not recommended for production use: `sismics/docs:latest`
+- Latest stable version: `sismics/docs:v1.11`

-Manual installation
-------------------
+The data directory is `/data`. Don't forget to mount a volume on it.

-#### Requirements
- Java 8 with the [Java Cryptography Extension](http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html)
- Tesseract 3 or 4 for OCR
+To build external URL, the server is expecting a `DOCS_BASE_URL` environment variable (for example https://teedy.mycompany.com)
+
+## Available environment variables
+
+- General
+  - `DOCS_BASE_URL`: The base url used by the application. Generated url's will be using this as base.
+  - `DOCS_GLOBAL_QUOTA`: Defines the default quota applying to all users.
+  - `DOCS_BCRYPT_WORK`: Defines the work factor which is used for password hashing. The default is `10`. This value may be `4...31` including `4` and `31`. The specified value will be used for all new users and users changing their password. Be aware that setting this factor to high can heavily impact login and user creation performance.
+
+- Admin
+  - `DOCS_ADMIN_EMAIL_INIT`: Defines the e-mail-address the admin user should have upon initialization.
+  - `DOCS_ADMIN_PASSWORD_INIT`: Defines the password the admin user should have upon initialization.  Needs to be a bcrypt hash.  **Be aware that `$` within the hash have to be escaped with a second `$`.**
+
+- Database
+  - `DATABASE_URL`: The jdbc connection string to be used by `hibernate`.
+  - `DATABASE_USER`: The user which should be used for the database connection.
+  - `DATABASE_PASSWORD`: The password to be used for the database connection.
+
+- Language
+  - `DOCS_DEFAULT_LANGUAGE`: The language which will be used as default. Currently supported values are:
+    - `eng`, `fra`, `ita`, `deu`, `spa`, `por`, `pol`, `rus`, `ukr`, `ara`, `hin`, `chi_sim`, `chi_tra`, `jpn`, `tha`, `kor`, `nld`, `tur`, `heb`, `hun`, `fin`, `swe`, `lav`, `dan`
+
+- E-Mail
+  - `DOCS_SMTP_HOSTNAME`: Hostname of the SMTP-Server to be used by Teedy.
+  - `DOCS_SMTP_PORT`: The port which should be used.
+  - `DOCS_SMTP_USERNAME`: The username to be used.
+  - `DOCS_SMTP_PASSWORD`: The password to be used.
+
+## Examples
+
+In the following examples some passwords are exposed in cleartext. This was done in order to keep the examples simple. We strongly encourage you to use variables with an `.env` file or other means to securely store your passwords.

-How to build Teedy from the sources
----------------------------------
+## How to build Teedy from the sources

-Prerequisites: JDK 8 with JCE, Maven 3, Tesseract 3 or 4
+Prerequisites: JDK 11, Maven 3, NPM, Grunt, Tesseract 4

 Teedy is organized in several Maven modules:

-  - docs-core

-  - docs-web-common
+- docs-core
+- docs-web
+- docs-web-common

 First off, clone the repository: `git clone git://github.com/sismics/docs.git`
 or download the sources from GitHub.

-#### Launch the build
+### Launch the build

 From the root directory:

-    mvn clean -DskipTests install
+```console
+mvn clean -DskipTests install
+```

-#### Run a stand-alone version
+### Run a stand-alone version

 From the `docs-web` directory:

-    mvn jetty:run
+```console
+mvn jetty:run
+```

-#### Build a .war to deploy to your servlet container
+### Build a .war to deploy to your servlet container

 From the `docs-web` directory:
