+***WARNING:** the instructions given in this documentation are not meant
+to be used for production environments since it will make **Authelia**
+non resilient to failures.*
+
+**NOTE:** If not done already, we highly recommend you first follow the
+[Getting Started] documentation.
+
+In some cases, like protecting personal websites, it can be fine to use
+**Authelia** in a non highly-available manner. Fortunately, we can
+achieve to run it along with one reverse proxy meaning the setup is
+then reduced to only two components: Authelia and nginx.
+
+As for a regular deployment in production, you need to install **Authelia**
+either by pulling the Docker image or installing the npm package and run
+it with a configuration file passed as argument.
+
+## Deploy with npm
+
+    npm install -g authelia
+    authelia /path/to/your/config.yml
+
+## Deploy with Docker
+
+    docker pull clems4ever/authelia
+    docker run -v /path/to/your/config.yml:/etc/authelia/config.yml clems4ever/authelia
+
+## Deploy Nginx
+
+You also need to install nginx and take [example/nginx/minimal/nginx.conf](./example/nginx/minimal/nginx.conf) as an example of configuration.
+
+## Discard components
+
+### Discard MongoDB
+
+There is an option in the configuration file to discard MongoDB and use
+your local filesystem to store the database data. This option will therefore
+prevent you from running multiple instances of **Authelia** in parallel.
+Consequently, this option is not meant to be used in production.
+
+Here is the configuration block you should use:
+
+    storage:
+      # The directory where the DB files will be saved
+      local:
+        path: /var/lib/authelia/store
+
+### Discard Redis
+
+There is an option in the configuration file to discard Redis and use the
+memory of the server to store the KV data. This option will therefore
+prevent you from running multiple instances of **Authelia** in parallel and
+will make you lose user sessions if the application restarts. This
+concretely means that all your users will need to authenticate again in
+that case. Hence, this option is not meant to be used in production.
+
+To use memory instead of a Redis backend, just comment out the Redis
+connection details in the following block:
+
+    session:
+      ...      
+      # # The redis connection details
+      # redis:
+      #  host: redis
+      #  port: 6379
+      #  password: authelia
+
+### Discard LDAP
+
+**Authelia** can use a file backend in order to store users instead of a
+LDAP server or an Active Directory. This mode will therefore prevent you
+from running multiple instances of **Authelia** in parallel and is therefore
+discouraged for production environments.
+
+To use a file backend instead of a LDAP server, you should first duplicate
+the file [users_database.yml](../users_database.yml) and edit it to add the
+users you want.
+
+The content of this file is as follows:
+
+    users:
+      ...
+      john:
+        password: "{CRYPT}$6$rounds=500000$jgiCMRyGXzoqpxS3$w2pJeZnnH8bwW3zzvoMWtTRfQYsHbWbD/hquuQ5vUeIyl9gdwBIt6RWk2S6afBA0DPakbeWgD/4SZPiS0hYtU/"
+        email: john.doe@authelia.com
+        groups:
+          - admins
+          - dev
+
+The password is hashed and salted as it is in LDAP servers with salted SHA-512. Here is a one-liner to generate such hashed password:
+
+    python3 -c 'import crypt; print("{CRYPT}" + crypt.crypt("mypassword", crypt.mksalt(crypt.METHOD_SHA512, rounds=500000)))'
+
+Once the file is created, edit the configuration file with the following
+block (as used in [config.minimal.yml](../config.minimal.yml)):
+
+    authentication_backend:
+      file:
+        path: /etc/authelia/users_database.yml
+
+instead of (used in [config.template.yml](../config.template.yml)):
+
+    authentication_backend:
+      ldap:
+        url: ldap://openldap
+        base_dn: dc=example,dc=com
+
+        additional_users_dn: ou=users
+        users_filter: cn={0}
+
+        additional_groups_dn: ou=groups
+        groups_filter: (&(member={dn})(objectclass=groupOfNames))
+
+        group_name_attribute: cn
+
+        mail_attribute: mail
+
+        user: cn=admin,dc=example,dc=com
+        password: password
+
+## FAQ
+
+### Can you give more details on why this is not suitable for production environments?
+
+This documentation gives instructions that will make **Authelia** non
+highly-available and non scalable by preventing you from running multiple
+instances of the application.
+This means that **Authelia** won't be able to distribute the
+load accross multiple servers and it will prevent failover in case of a
+crash or an hardware issue. Moreover, it will also prevent from reliably
+persisting data and consequently fail access to your platform as the devices
+registered by your users will be lost.
+
+### Why is this not automated?
+
+Well, as stated before those instructions are not meant to be applied for
+a production environment. That being said, in some cases it is just fine and
+so writing an Ansible playbook to automate all this process would be great.
+We would really be more than happy to review such a PR.

+# Deployment for Production
+
+**Authelia** can be deployed on bare metal or on Kubernetes with two
+different kind of artifacts: an npm package or a Docker image.
+
+**NOTE:** If not done already, we highly recommend you first follow the
+[Getting Started] documentation.
+
+## On Bare Metal
+
+**Authelia** has been designed to be a proxy companion handling the 
+authentication and authorization requests for your entire infrastructure.
+
+As **Authelia** will be key in your architecture, it requires several
+components to make it highly-available. Deploying it in production means having an LDAP server for storing the information about the users, a Redis cache to store the user sessions in a distributed manner, a
+MongoDB to persist user configurations and one or more nginx reverse proxies configured to be used with Authelia. With such a setup **Authelia** can easily be scaled to multiple instances to evenly handle the traffic.
+
+**NOTE:** If you don't have all those components, don't worry, there is a way to deploy **Authelia** with only nginx. This is described in [Deployment for Devs].
+
+Here are the available steps to deploy **Authelia** given 
+the configuration file is **/path/to/your/config.yml**. Note that you can
+create your own configuration file from [config.template.yml] located at
+the root of the repo.
+
+### Deploy With NPM
+
+    npm install -g authelia
+    authelia /path/to/your/config.yml
+
+### Deploy With Docker
+
+    docker pull clems4ever/authelia
+    docker run -v /path/to/your/config.yml:/etc/authelia/config.yml clems4ever/authelia
+
+## On top of Kubernetes
+
+<img src="/images/kube-logo.png" width="24" align="left">
+
+**Authelia** can also be used on top of [Kubernetes] using [nginx ingress
+controller](https://github.com/kubernetes/ingress-nginx).
+
+Please refer to the following [documentation](../example/kube/README.md)
+for more information.

+
+## FAQ
+
+### Why is this not automated?
+
+Ansible would be a very good candidate to automate the installation of such
+an infrastructure on bare metal. We would be more than happy to review any PR on that matter.
+
+Regarding Kubernetes, the right way to go would be to write a helm recipe.
+Again, we would be glad to review any PR implementing this.
