+# SDK Developer Documentation
+
+This file documents developing the SDK itself. If you simply wish to use the SDK or run examples, see [README.md](./README.md)
+
+## Setup
+
+- Install JDK 17
+  - Recommended to use SDK Man: https://sdkman.io/ and `sdk use java 17.0.16-tem`
+- Ensure you can run all tests and checks: `./gradlew check build`
+- IDE Setup
+  - Intellij Community
+    - Ubuntu: `sudo snap install intellij-idea-community`
+    - Other: https://www.jetbrains.com/idea/download/
+- (Optional) Install pre-commit hooks: `./gradlew installGitHooks`
+  - These hooks automatically run common checks for you but CI also runs the same checks before merging to the main branch is allowed
+  - NOTE: this will overwrite existing hooks. Take backups before running
+
+## Running a local OpenTelemetry collector
+
+OpenTelemetry provides a local collector with a debug exporter which logs all traces, logs, and metrics to stdout.
+
+To run a local collector:
+
+```
+# Assumes you're in the repo root
+docker run --rm -p 4318:4318 -v "$PWD/localcollector/collector.yaml:/etc/otelcol/config.yaml" otel/opentelemetry-collector:0.136.0 # latest release will probably also work
+```
+
+To send Braintrust otel data to the local collector:
+
+```
+# assumes you have BRAINTRUST_API_KEY and OPENAI_API_KEY exported
+export BRAINTRUST_API_URL="http://localhost:4318" ; export BRAINTRUST_TRACES_PATH="/v1/traces"; export BRAINTRUST_LOGS_PATH="/v1/logs" ; ./gradlew :examples:runOpenAIInstrumentation
+```

 All Braintrust loggers will log into the `dev.braintrust` namespace. To adjust the log level, consult your logger documentation.
 
 For example, to enable debug logging for slf4j-simple you would set the system property `org.slf4j.simpleLogger.log.dev.braintrust=DEBUG`
