Silkscreen in PCB

Hey guys, up with a new query. Can anyone please tell me briefly how I can add silkscreens on my PCB board? By the way I'm using Eagle software. Thanks in advance.

The layer 21 & 22 (tplace & bplace) are the silkscreen layer. These two layers contain both the top and bottom silkscreen on your PCB and also component outlines to show the positioning of components. You need to be careful when using this layer not to place silkscreen on any soldered areas.
As an alternative to these layers, consider placing additional silkscreen on Layer 51: tDocu for your own personal reference like comments in programming. This layer won’t be included in your manufacturing data or printed on your PCB so that you can include a lot more details. However, if you want to add any kind of additional artwork outside of regular silkscreen, like text or logos, then use Layer 21-22 as I mentioned earlier.
Let me know anything more you need to know!

@Suhailjr Thank you Soo much for the answer.
@Richu-Bini thanks for posting the question . just for a brief about pwm, pulse width modulation technique is a method to change the duty cycle of a wave. Which means you can determine how much time a signal must be on or off.
So, coming to the question, software pwm and hardware pwm is just two different ways of producing same result. In software(referring Arduino here) you'll just write a value between 0 to 255 inorder to determine duty cycle percentage. For example 0 is 0% duty cycle which means the cycle is on for 0% of whole time, similarly 127 means 50% of time cycle will be on and 255 means signal will be on for ever. This is regarding software.
Coming to hardware, you can generate a pwm signal using very simple passive component, called as potentiometer and 555 timer IC by using 555 timer as bistable multivibrator(The generated output will have two stable states 0 and Vmax, hence the name bistable) and changing the resistance using a potentiometer generates different duty cycles. This is the difference between hardware and software pwm. Please let me know if I haven't explained what you have expected.
This month we are discussing Psychology and Perils of Polyglot/Mixed Language Programming

Nowadays, every developer in the world ought to be a Polyglot (Programmer) to do something worthwhile in the industry. But, most are not prepared to get into that groove. The Session will give necessary conceptual, ontological, linguistic and formal background to navigate between programming languages with ease. The Session has got examples in C++, C#, Java, Scala, Python, JS, Python/C interface, Java Native Interface, P/Invoke, COM interop, RxJava/RxJS./Rxcpp/Rx.net etc. All code snippets are taken from real-life projects which the presenter has been part of, in the past two decades. The session also covers some pitfalls which an aspiring Polyglot Programmer should be watchful, as well.
Don't miss it, book your seats today. It's a golden opportunity for all Enthusiasts to listen from the true industry experts!

What is the difference between hardware pwm and software pwm
flat end leaves flat surface profile on the stock and are good for removing large volume of material, but steps are formed when used for making curved surfaces. Ball end leaves curved surfaces and forms smooth curved finish while cutting cavities. They are used for finishing cuts.
