+# Coding standards, domain knowledge, and preferences that AI should follow
+
+## C# Coding Standards
+
+- Use the csharpier formatter for formatting C# code.
+- Use the .editorconfig file for code style settings.
+- Always use `var` when the type is obvious from the right side of the assignment.
+- Always add braces for `if`, `else`, `for`, `foreach`, `while`, and `do` statements, even if they are single-line statements.
+
+## Testing
+
+- Use xUnit for unit testing.
+- Use FluentAssertions for assertions in tests.
+- Use Moq for mocking dependencies in tests.

+# Git Commit Instructions
+
+To ensure high-quality and consistent commits, please follow these guidelines:
+
+1. **Format your code**
+    - Run the `csharpier` formatter on all C# files before committing.
+    - Ensure your code adheres to the `.editorconfig` settings.
+
+2. **Write clear commit messages**
+    - Use the present tense ("Add feature" not "Added feature").
+    - Start with a short summary (max 72 characters), followed by a blank line and a detailed description if necessary.
+
+3. **Test your changes**
+    - Run all unit tests before committing.
+    - Add or update xUnit tests as needed.
+    - Use AwesomeAssertions for assertions and Moq for mocking in tests.
+
+4. **Review your changes**
+    - Double-check for accidental debug code or commented-out code.
+    - Ensure only relevant files are staged.
+
+Thank you for helping maintain code quality!

 > [!WARNING]
-> This is an early beta release, not meant for use in production! We're working to stabilise the 3.0 API, and until then there will be breaking changes. You have been warned!
+> Releases Speckle.Sdk and Speckle.Objects are reliable for production use, but the APIs may not be wholly stable, and there may be breaking changes between releases, with little documentation.

 This repo is the home of our next-generation Speckle .NET SDK. It uses .NET Standard 2.0 and has been tested on Windows and MacOS.
 
 - **SDK**
-  - [`Speckle.Sdk`](https://github.com/specklesystems/speckle-sharp-sdk/tree/dev/src/Speckle.Sdk): Transports, serialization, API wrappers, and logging.

   - [`Speckle.Sdk.Dependencies`](https://github.com/specklesystems/speckle-sharp-sdk/tree/dev/src/Speckle.Sdk.Dependencies): Dependencies and code that shouldn't cause conflicts in Host Apps.  This uses [IL Repack](https://github.com/gluck/il-repack) to merge together and interalized only to be used by Speckle.
+  - [`Speckle.Automate.Sdk`](https://github.com/specklesystems/speckle-sharp-sdk/tree/dev/src/Speckle.Automate.Sdk): .NET SDK for [Speckle Automate](https://www.speckle.systems/product/automate)
 - **Speckle Objects**

 ### Building
 
-Make sure you clone this repository together with its submodules: `git clone https://github.com/specklesystems/speckle-sharp-sdk.git -recursive`.
-Afterwards, just restore all the NuGet packages and hit Build!
+Ensure you're using a [8.0.4xx](https://dotnet.microsoft.com/en-us/download/dotnet/8.0) .NET SDK. 
+After cloning this repository, just restore all the NuGet packages and hit Build!
 
 ### Developing
 
-This project is evolving fast, to better understand how to use Core we suggest checking out the Unit and Integration tests. Running the integration tests locally requires a local server running on your computer.
+It is highly recommended you use
+ - Either Jetbrains Rider or Visual Studio 2022
+ - Ensure your IDE is set to use [the correct .NET SDK version](https://github.com/specklesystems/speckle-sharp-sdk/blob/main/global.json) (newer major versions may work, but may incorrectly run analysers we haven't configured)
+ - You should install the cshapier plugin ([Rider](https://plugins.jetbrains.com/plugin/18243-csharpier), [VS](https://marketplace.visualstudio.com/items?itemName=csharpier.CSharpier)) and configure it to run on save
 
-We'll be also adding [preliminary documentation on our forum](https://discourse.speckle.works/c/speckle-insider/10).
+Docs are a bit patchy [https://docs.speckle.systems/developers/looking-for-developer-docs](https://docs.speckle.systems/developers/looking-for-developer-docs)
 
 ### Tests
 
-There are two test projects, one for unit tests and one for integration tests. The latter needs a server running locally in order to run.
+There are several test projects. It is a requirement that all tests pass for PRs to be merged.
 
+The Integration test projects require a local server to be running.
+You must have docker installed. Then you can run `docker compose up` from the root of the repo to start the required containers.
+
+In CI, they will be run against both the public and private versions of the server.
+It is important that we remain compatible with both server versions.
