-Это зачаток программы управления данными на основе описания структуры в json формате.
+# Это зачаток программы управления данными на основе описания структуры в json формате.
+Пишется на python3 в качестве графической библиотеки Qt5.
+
+# Использование
+
+По умолчанию используется шаблон и БД 'dm'. Для того чтобы изменить БД, создаем JSON шаблон согласно описания (см. примеры в db_template).
+
+Затем данный файл нужно скопировать в '~/.dm/db_template/', следущим шагом меняем в конфиге 'dm.cfg' имя БД на имя вашего шаблона без расширения json, т.е. к примеру для работы с книжным каталогом (файл db_template/library.json) файл настроек будет выглядеть следующим оюбразом: 
+
+```
+[DataBase]
+db_type = sqlite
+db_hostname = localhost
+db_name = library
+db_user = dm
+db_password = password
+
+[Directory]
+work_dir = /home/svkalinin/.dm
+template_dir = /home/svkalinin/.dm/db_template
+
+```
+
+После этого можно запустить программу, при первом запуске будет создана БД согласно шаблона:
+    
+```
+python3 gui.py
+```
+
+# СУБД
+
+Пока реализована работа с Mysql (или Mariadb) и sqlite (по умолчанию). Для из менения типа БД в конфиге меняем 'dbtype':
+
+```
+dbtype = sqlite
+
+или
+
+dbtype = mysql
+```
