**Introduction**
This tutorial episode, regarding the programming language Ruby. This is the first of many. 
This tutorial is intended for every and anybody interested in Ruby programming; it doesn't matter if you're an absolute beginner programming in Ruby, or even any programming language, if you already have an intermediate skillset or if you are already a very proficient Ruby programmer. 

**lesson of the day**

I will suggest doing it on Linux operating system ( Ubuntu 16.04).
If you are on windows, there Is an easier way of installing ruby. 
You can do that through rubyinstaller. 
Which can be found here.     https://rubyinstaller.org/downloads/

If using Linux operating system follow the steps below 
**STEPS**

Execute this command in your terminal, we are going to installing ruby via rbenv. 

    git clone


      Https://github.com/rbenv/rbenv.git




    ~/ .rbenv

After cloning rbenv, execute these commands. 

    echo 'export

    PATH="$HOME/.rbenv/bin:$PATH"' >> 

    ~/.bashrc

    echo 'eval "$(rbenv init -)"' >> 

    ~/.bashrc

Next is sourcing rbenv

    Source ~/.bashrc

After sourcing, check to see if rbenv is installed properly using 

    type rbenv

Your output should be similar to this

Following command will allow us to use *rbenv install* command which will come in handy when installing different version of ruby programming language. 
If you wish to clone a github project and it is built with different version of  language
rbenv install command helps us switch between different version of ruby programming language. 

It requires only one command to install a different version of ruby

    git clone
---
       https://git.com/rbenv/ruby-build.git
---
    ~/.rbenv/plugins/ruby-build

![DQmVhm8Zm9BxbfJNXe6SaE5Sk2t4oHmqFVDwneBEwyDuveX.png](https://steemitimages.com/DQmVhm8Zm9BxbfJNXe6SaE5Sk2t4oHmqFVDwneBEwyDuveX/DQmVhm8Zm9BxbfJNXe6SaE5Sk2t4oHmqFVDwneBEwyDuveX.png)

The following command allows us to see, what version of ruby programming language are available .
You can pick any version from the list to install

    rbenv install -1
![DQmNdqFY7FqE4UzBqWRFwtKqXXNctiAL6HdPc1XXHiMGv3V_1680x8400.png](https://steemitimages.com/DQmcgLbiqcnXKrJLD2RJpEYvx4AvnN4fpRw8RFcCunncrhc/DQmNdqFY7FqE4UzBqWRFwtKqXXNctiAL6HdPc1XXHiMGv3V_1680x8400.png)

Next is to install the version of ruby programming  you picked. 
In this case we will install ruby 2.5.0 which is  latest stable 
    rbenv install 2.5.0

![DQmWCKbZ9qxSMe6cbbmDUAkc8HKfFQZV75ciedP84SdR82a.png](https://steemitimages.com/DQmWCKbZ9qxSMe6cbbmDUAkc8HKfFQZV75ciedP84SdR82a/DQmWCKbZ9qxSMe6cbbmDUAkc8HKfFQZV75ciedP84SdR82a.png)

If you installed lots of versions, I will advice you to set a default version for your ruby programs by typing and exciting 
    rbenv global 2.5.0

Verify if everything is installed perfectly  you can do that by executing this command 
    ruby - v

Which returns us to the version of ruby which we just installed 

![DQmPMHcCCnU4CmUoj9u2vmVQQqNDvu5hNQFNbwEoBx1xs3x_1680x8400.png](https://steemitimages.com/DQmYAyqtPvudhWL2Cz6xfX6BeW3zNXHairXKrFTUFDNVJrs/DQmPMHcCCnU4CmUoj9u2vmVQQqNDvu5hNQFNbwEoBx1xs3x_1680x8400.png)

If you have done everything correctly then you just installed ruby development environment. 

**What will be covered in the remaining tutorial of ruby programming**

We have a lot to cover even though this turned out to be quite a lengthy introduction to ruby programming language, we only barely scratched the surface of what can be done using Ruby. 
Lesson two will be on constant values and data types
