+# csv2md
+
+Stupidly simple tool to convert csv-file to [markdown](https://spec-md.com/) table.
+
+Outputs result in stdout.
+
+Building:
+
+```shell
+make help
+```
+
+Usage:
+
+```shell
+csv2md example.csv > example.md # makes new file
+csv2md example.csv | less       # view result using *pager*
+...anything is possible with redirection and piping
+```
+
+> **IMPORTANT:** input must be valid csv and whitespaces are allowed only between double-quotes.
+
+Examples can be found here: https://people.sc.fsu.edu/~jburkardt/data/csv/csv.html
