-The Django Accounting application.
-
-## Description
-
-`mia-accounting` is a Django accounting application.  It was a re-write of my
-own private accounting application written in Perl for `mod_perl` in 2007.  The
-revision aims to be mobile-friendly with Bootstrap, with a modern back-end
-framework and front-end technology like jQuery.  The first revision was in
-Perl / Mojolicious in 2019.  This is the second revision in Python / Django
-in 2020.
-
-`mia-accounting` comes with two parts:
-
-* The `accounting` application contains the main accounting application. 
-
-* The `mia_core` application contains core shared libraries that are used by the
-accounting application and my other applications.
-
-You may try it in live demonstration at
-https://accounting.imacat.idv.tw/accounting .
-* Username: `admin`
-* Password: `12345`
