 These are simple implementations only, so for actual use it is recommended creating your own implementations as needed.
 
+## Development
+
+The repository uses the .NET SDK and can be built from the repo root.
+
+### Build
+
+```sh
+dotnet build Lua.slnx -c Release
+```
+
+If you only want to build the NuGet package project:
+
+```sh
+dotnet build src/Lua/Lua.csproj -c Release
+```
+
+### Run Tests
+
+```sh
+dotnet test tests/Lua.Tests/Lua.Tests.csproj -c Release
+```
+
+### Inherited Lua Tests
+
+The test project includes a set of `.lua` conformance-style tests inherited from the official Lua repository. Most of them are expected to pass, but a few known cases are currently marked with the `ExpectedFailure` category in the test suite.
+
+To run the test project while excluding those known failures:
+
+```sh
+dotnet test tests/Lua.Tests/Lua.Tests.csproj -c Release --filter "TestCategory!=ExpectedFailure"
+```
+
+This is the same filter used in GitHub Actions when packing and publishing the NuGet package.
+
+### Pack for NuGet
+
+```sh
+dotnet pack src/Lua/Lua.csproj -c Release -o ./artifacts/nuget
+```
+
+The package version is defined in `Directory.Build.props`. After packing, the `.nupkg` file will be written to `artifacts/nuget/`.
+
 ## Compatibility
 
 Lua-CSharp is designed with integration into .NET in mind, so there are several differences from the C implementation.
