 ## Installation
 
-### Development Setup
+### Environment setup
 
 ```bash
 git clone https://github.com/getsentry/launchpad.git
 cd launchpad
+
+# Installs our local dependencies
 devenv sync
 ```
 
 If you don't have devenv installed, [follow these instructions](https://github.com/getsentry/devenv#install).
 
 ### Using devservices
 
-[devservices](https://github.com/getsentry/devservices) provides shared Kafka infrastructure used by multiple Sentry services:
+[devservices](https://github.com/getsentry/devservices) manages the dependencies used by Launchpad:
 
 ```bash
-# Start shared dependencies (Kafka)
+# Start dependency containers (e.g. Kafka)
 devservices up
 
-# In another terminal, start the service
+# Begin listening for messages
 launchpad serve
 
-# Or run integration tests
-make test-service-integration
-
-# Stop shared dependencies
+# Stop containers
 devservices down
 ```
 
 ## Usage
 
-### Testing Kafka Integration
+Launchpad is primarily designed to run as a Kafka consumer alongside the [Sentry monolith](https://github.com/getsentry/sentry) codebase via `launchpad serve`.
 
-- `GET /health` - Basic health check
-- `GET /ready` - Readiness check
+Alternatively for a one-off analysis, such as a local size analysis, you can invoke our various CLI subcommands.
 
-### Testing Kafka Integration
+### Size command
 
 ```bash
-# Send a test message to Kafka
-make test-kafka-message
-
-# Send multiple test messages
-make test-kafka-multiple
-```

 ### Service Development
 
+For full end-to-end development alongside the Sentry monolith, first run `sentry` in one terminal:
+
 ```bash
-# Development with shared infrastructure
-devservices up                  # Start Kafka via devservices
+devenv sync
+devservices up --mode ingest
+devservices serve --workers
+```
+
+Next run `launchpad` in another terminal:
+
+```bash
+devservices up
 launchpad serve
 ```
 
+And finally use the `sentry-cli` to upload to your local machine:
+
+```bash
+sentry-cli --log-level DEBUG \
+  --url http://dev.getsentry.net:8000/ \
+  --auth-token $SENTRY_TOKEN \
+  build upload YourBuild.xcarchive \
+  --org sentry \
+  --project internal
