+## Tech stack
+
+- golang
+- typescript, vite and svelt5 for UI (located in ui/)
+
+## Workflow Tasks
+
+- when summarizing changes only include details that require further action
+- just say "Done." when there is no further action
+- use the github CLI `gh` to create pull requests and work with github
+- Rules for creating pull requests:
+  - keep them short and focused on changes.
+  - never include a test plan
+  - write the summary using the same style rules as commit message
+
+## Testing
+
+- Follow test naming conventions like `TestProxyManager_<test name>`, `TestProcessGroup_<test name>`, etc.
+- Use `go test -v -run <name pattern for new tests>` to run any new tests you've written.
+- Use `make test-dev` after running new tests for a quick over all test run. This runs `go test` and `staticcheck`. Fix any static checking errors. Use this only when changes are made to any code under the `proxy/` directory
+- Use `make test-all` before completing work. This includes long running concurrency tests.

+These scripts create a custom llama-swap container that contains:
+
+- llama-server for LLMs, rerank and embedding model support
+- sd-server (stable-diffusion.cpp) for image generation
+- whisper.cpp for ASR
