How to read a markdown file in another markdown file?

问题

My purpose is to collect many descriptions written in markdown to a single markdown file for an integrated article.

For instance, in ./f1/a.md

This is the description for f1 project. 

and in ./b.md

The introduction of f1 project is shown below, 
<!-- Contain of the a.md goes here -->

The expected result of the b.md should be,

The introduction of f1 project is shown below, 
This is the description for f1 project. 

So, how can I achieve this function?

Markdown itself doesn't support file inclusions, but depending on the Markdown processor you are using you've got a couple of options:

• Some Markdown processors support multiple input files. For example, Pandoc can take multiple input files and generate a single output file:

  pandoc -o output.html one.md two.md three.md
  

• You could simply concatenate your individual source files together in the correct order, then use that concatenated file as a single input for a less flexible parser:

  cat one.md two.md three.md > source.md
  markdown source.md
  

  If you are on Windows you will probably need to replace cat with type.

  Depending on the complexity of your input, you may want to automate this process. A tool like make could help with this.
