Hey @chroniclefresh,

thanks for your article. However, since you are using the #steemstem tag there are some things to consider:

• Check out the steemSTEM-guidelines to see, which standards are needed to be fulfilled for using the steemstem tag.

• Just referring to a youtube-video as a source is not enough. Additionally you are violating copyrights, since you are using it for commercial purposes. See this for additional information.

If there are any additional questions, feel free to ask.

Best regards
Ego
