+# GravitLauncher GitConvention #
+
+Цель конвенции — внедрить простые, прозрачные и эффективные правила работы с Git.
+
+Разработка GravitLauncher идёт на базе [Git Flow](https://leanpub.com/git-flow/read). Подробности ниже.
+
+## Ветвление ##
+
+| Название ветки | Значение ветки | Исходная ветка | Пример ветки |
+| ------------- | ------------- | ------------- | ------------- |
+| **master**  | Полностью готовая для production-а | **release** | |
+| **develop**  | Разработка нового функционала  | **master** | |
+| **release**  | Тестирование всего нового функционала | **develop** | |
+|  |  |  | |
+| **bugfix-***  | Исправляет баг нового функционала | **release** | *bugfix-auth* |
+| **feature-***  | Добавляет новую возможность  |  **develop** | *feature-auth* |
+| **hotfix-***  | Вносит срочное исправление для production-а  |  **master** | *hotfix-auth* |

+
+## Коммиты ##
+
+**Основные правила:**
+
+1. Все коммиты должны быть на английском языке.

+3. Обязательно должен быть использован префикс.
+4. В конце не должно быть лишнего знака препинания.
+5. Длина любой части не должна превышать 100 символов.
+
+**Структура:**
+
+```
+[Префикс] <Сообщение>                             
+```
+
+| Префикс | Значение | Пример |
+| ------- | -------- | ------ |
+| **[FIX]** | Всё, что касается исправления багов | [FIX] Bug with failed authorization |
+| **[DOCS]** | Всё, что касается документации | [DOCS] Documenting Authorization API |
+| **[FEATURE]** | Всё, что касается новых возможностей | [FEATURE] 2FA on authorization |
+| **[STYLE]** | Всё, что касается опечаток и форматирования | [STYLE] Typos in the authorization module |
+| **[REFACTOR]** | Всё, что касается рефакторинга | [REFACTOR] Switching to EDA in the authorization module |
