+# 🇺🇸 Assets downloader
+
+> ⚠️ write it...
+
+# 🇷🇺 Загрузчик ассетов
+
+Утилита, которая встраивается в основной скрипт и скачивает ассеты из сети.
+
+Используется программа на **Си** для парсинга файла индексов ассетов.
+
+## About assets
+
+The game itself downloads (through the launcher) further resources from
+
+```text
+https://resources.download.minecraft.net/
+```
+
+> ⚠️ http://resources.download.minecraft.net/ no longer works - you must use https
+
+The asset index for each version is linked in the `<version>.json`. An example url to the asset index could look like this
+
+```text
+https://launchermeta.mojang.com/mc/assets/1.12/67e29e024e664064c1f04c728604f83c24cbc218/1.12.json
+```
+
+Each resource in the file has a name (the field name of the resource object), a SHA1 hash, and a file size. The client currently downloads all resources in the index from
+
+```text
+https://resources.download.minecraft.net/<first 2 hex letters of hash>/<whole hash>
+```
+
+and stores them in
+
+```text
+.minecraft/assets/objects/<first 2 hex letters of hash>/<whole hash>
+```
+
+and a copy is stored in
+
+```text
+.minecraft/assets/virtual/legacy/ 
+```
+
+in the old format for versions that don't support the new system (1.7 and below)
