 # Changelog
 
+## [Unreleased]
+
+### RU
+
+**Добавлено:**
+
+- **Зеркала загрузок в `dcrup`** — `--mirror auto|cf|gh|sf|ya` и `DCRUP_MIRROR`.
+  По умолчанию `auto`: **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
+
+**Удалено:**
+
+- **`install.sh` / `install.ps1` / `install_bsd.sh`** — устарели, заменены `dcrup`.
+
+### EN
+
+**Added:**
+
+- **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
+  Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
+
+**Removed:**
+
+- **`install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
+

+## Repository Mirrors
+
+The primary repository is hosted on GitHub. Source and release mirrors:
+
+| Region | Mirror | Contents |
+|---|---|---|
+| Worldwide | [GitHub](https://github.com/dexoron/dcr) | Source code and releases |
+| Worldwide | [SourceForge](https://sourceforge.net/projects/dcr-tool/) | Source code and releases |
+| Russia | [GitVerse](https://gitverse.ru/dcr_labs/dcr) | Source code |
+| Russia | [SourceCraft](https://sourcecraft.dev/dexoron-dev/dcr) | Source code |
+
+Release CDN (used by `dcrup`):
+
+| Code | Host | Role |
+|---|---|---|
+| `cf` | [cdn-global.dcr-tool.ru](https://cdn-global.dcr-tool.ru) (CloudFlare) | Worldwide CDN |
+| `gh` | GitHub Releases | Primary host |
+| `sf` | SourceForge | Worldwide fallback |
+| `ya` | [cdn-ru.dcr-tool.ru](https://cdn-ru.dcr-tool.ru) (Yandex) | Paid RU fallback for restrictions |
+
+`dcrup install` defaults to `--mirror auto` and tries **cf → gh → sf → ya**. Override with `--mirror cf|gh|sf|ya` or `DCRUP_MIRROR`.
+
+---
+
+## VS Code Extension
+
+Install the recommended [DCR extension by Dexoron-Labs](https://marketplace.visualstudio.com/items?itemName=Dexoron-Labs.dcr) for VS Code. Do not install Microsoft C/C++ extensions for DCR projects; DCR uses `clangd` instead. If you need debugging with Microsoft's debugger, use MS C/C++ only for its debugger component.
+
+Recommended companion extensions:
+
+- [Even Better TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml)
+- [CodeLLDB](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb), or MS C/C++ for debugger support only

 # Changelog
 
+## Unreleased
+
+- **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
+  Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
+- **Removed `install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
+
 ## 0.8.5 (2026-08-08)
 
 - **`package.dcr-version`** — optional CLI version pin in `dcr.toml`.

 `dcr.lock` is created during builds (`dcr build`) when registry dependencies are present. To force an update — delete `dcr.lock` and run `dcr build`.
