 ## Prerequisites
 
+- Install
+[docker](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04)
+  and
+[docker-compose](https://www.digitalocean.com/community/tutorials/how-to-install-docker-compose-on-ubuntu-18-04)
+
+- Make sure you have access to Blindside Networks private repository in
+  [dockerhub](https://cloud.docker.com/u/blindsidenetwks/repository/list) particularly to:
+
+  - [scalelite](https://cloud.docker.com/u/blindsidenetwks/repository/docker/blindsidenetwks/scalelite)
+
+- Make sure you have your own DNS and a public domain name or a delegated one under blindside-dev.com
+  (e.g. <JOHN>.blindside-dev.com)
+
 
 ## Preliminary steps
 
 
 ## Steps
+
+Clone this repository:
+
+```
+git clone git@github.com:blindsidenetworks/scalelite-run.git
+cd scalelite-run
+```
+
+Copy  `dotenv` file located in the root of the project as `.env` and edit it
+
+```
+vi .env
+```
+
+You will need to replace both variables as in:
+`DOMAIN_ROOT=bigbluebutton.org` to the one assigned to you (e.g. `DOMAIN_ROOT=blindside-dev.com`)
+`DOMAIN_SUB=lab` to the one assigned to you (e.g. `DOMAIN_SUB=<JOHN>`)
+
+Create your own SSL Letsencrypt certificates. As you are normally going to
+have this deployment running on your own computer (or in a private VM), you
+need to generate the SSL certificates with certbot by adding the challenge to
+your DNS.
+
+Install letsencrypt in your own computer
+
+```
+sudo apt-get update
+sudo apt-get -y install letsencrypt
+```
+
+Make yourself root
+
+```
+sudo -i
+```
+
+Start creating the certificates
+
+```
+certbot certonly --manual -d sl.<JOHN>.blindside-dev.com --agree-tos --no-bootstrap --manual-public-ip-logging-ok --preferred-challenges=dns --email hostmaster@blindsdie-dev.com --server https://acme-v02.api.letsencrypt.org/directory
+```
+
+You will see something like this
+```
+-server https://acme-v02.api.letsencrypt.org/directory
+Saving debug log to /var/log/letsencrypt/letsencrypt.log
+Plugins selected: Authenticator manual, Installer None
+Obtaining a new certificate
+Performing the following challenges:
+dns-01 challenge for gl.<JOHN>.blindside-dev.com
+dns-01 challenge for gl.<JOHN>.blindside-dev.com
+
+- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
+Please deploy a DNS TXT record under the name
+_acme-challenge.sl.<JOHN>.blindside-dev.com with the following value:
+
+2dxWYkcETHnimmQmCL0MCbhneRNxMEMo9yjk6P_17kE
+
+Before continuing, verify the record is deployed.
+- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
+Press Enter to Continue
+```
+
+Create a TXT record in your DNS for
+`_acme-challenge.sl.<JOHN>.blindside-dev.com` with the challenge string as
+its value `2dxWYkcETHnimmQmCL0MCbhneRNxMEMo9yjk6P_17kE`
+
+Copy the certificates to your scalelite-run directory. Although `/etc/letsencrypt/live/`
+holds the latest certificate, they are only symbolic links. The real files must be copied and renamed
+
+```
+cp -R /etc/letsencrypt/archive/sl.<JOHN>.blindside-dev.com <YOUR ROOT>/scalelite-run/nginx/letsencrypt/live
+```
+
+```
+cd <YOUR ROOT>/scalelite-run/nginx/letsencrypt/live/sl.<JOHN>.blindside-dev.com/
+mv cert1.pem cert.pem
+mv chain1.pem chain.pem
+mv fullchain1.pem fullchain.pem
+mv privkey1.pem privkey.pem
+```
+
+As you have to have access to dockerhub private repositories sign in into docker hub with your account
+with `docker login -u <YOUR_USERNAME> -p <YOUR_PASSWORD>` or `docker login -u <YOUR_USERNAME>` if you
+want to type your password using the stdin
+
+And finally, start your environment with docker-compose
+
+```
+cd <YOUR ROOT>/scalelite-run
+docker-compose up
+```
+
+If everything goes well, you will see all the containers starting and at the
+end you will have access to scalelite through:
+
+```
+https://sl.<JOHN>.blindside-dev.com/bigbluebutton/api
+```
