+# Project Guidelines
+
+## Repository Structure
+- The repository and the app consist of a Rust project in the `runtime` folder and a .NET solution in the `app` folder.
+- The .NET solution then contains 4 .NET projects:
+  - `Build Script` is not required for running the app; instead, it contains the build script for creating new releases, for example.
+  - `MindWork AI Studio` contains the actual app code.
+  - `SharedTools` contains types that are needed in the build script and in the app, for example.
+  - `SourceCodeRules` is a Roslyn analyzer project. It contains analyzers and code fixes that we use to enforce code style rules within the team.
+
+## Changelogs
+- There is a changelog in Markdown format for each version.
+- All changelogs are located in the folder `app/MindWork AI Studio/wwwroot/changelog`.
+- These changelogs are intended for end users, not for developers.
+- Therefore, we don't mention all changes in the changelog: changes that end users wouldn't understand remain unmentioned. For complex refactorings, for example, we mention a generic point that the code quality has been improved to enhance future maintenance.
+- The changelog is always written in US English.
+- The changelog doesn't mention bug fixes if the bug was never shipped and users don't know about it.

 # v0.9.51, build 226 (2025-08-xx xx:xx UTC)
+- Added support for predefined chat templates in configuration plugins to help enterprises roll out consistent templates across the organization.
 - Improved memory usage in several areas of the app.
+- Improved plugin management for configuration plugins so that hot reload detects when a provider or chat template has been removed.
 - Fixed a bug in various assistants where some text fields were not reset when resetting.
