Markdown is a lightweight markup language that many technical professionals use to create and edit technical documents.

## bash and ksh
**bash** closely resembles an older shell named **ksh**.  The key
*practical* difference between the two shells is as follows:
*  More people know bash than ksh, so it is easier to get help for bash
   problems than ksh problems.
The rendered version of the preceding technical document looks as follows:
bash and ksh
bash closely resembles an older shell named ksh. The key practical difference between the two shells is as follows:
- More people know bash than ksh, so it is easier to get help for bash problems than ksh problems.
