-# Indy sidecar
+# Indy Sidecar
 
+A Quarkus-based sidecar service that optimizes build performance by pre-downloading and caching dependency artifacts from previous builds. Deployed within builder pods, it proxies download/upload requests to remote repositories while serving cached artifacts locally to accelerate builds.
 
-## build image
+## Architecture
 
-**JVM image**
+- **Proxy Service**: Routes HTTP requests (GET/POST/PUT/DELETE/HEAD) to configured remote services
+- **Archive Retrieval**: Downloads artifact zip files from the external Archive Service for each build config
+- **Tracking Service**: External service that records artifact information sent by the sidecar
 
-```shell
-./mvnw clean package -Dquarkus.container-image.build=true
-```
+## Workflow
+
+1. **Archive Generation**: After a build completes, users trigger artifact zip file generation via REST API to the Archive Service
+2. **Zip Download**: The sidecar downloads the latest artifact zip file for the current build from the Archive Service
+3. **Local Caching**: Downloaded artifacts are cached locally and served directly to current build
+4. **Proxy Fallback**: For artifacts not in cache (new dependencies), requests are proxied to remote repositories
+5. **Records Collection**: All download/upload operations are sent to the external Tracking Service for recording and observability
 
-use `src/main/resources/application.properties` to control image build plugin, by default, indy-sidecar use docker as builder.
+## Configuration
 
----
+Configure via `application.yaml`:
 
-**Native executable**
+```yaml
+sidecar:
+  archive-api: http://localhost:8081/api/archive
+  local-repository: ${user.home}/preSeedRepo
+
+proxy:
+  read-timeout: 30m
+  retry:
+    count: 3
+    interval: 3000
+  services:
+    - host: your-repo-host
+      port: 80
+      path-pattern: /api/.+
+```
 
+## Build & Deploy
 
-```shell
+**JVM Image:**
+```bash
+./mvnw clean package -Dquarkus.container-image.build=true
+```
+
+**Native Executable:**
+```bash
 ./mvnw package -Pnative -Dquarkus.native.container-build=true
 docker build -f src/main/docker/Dockerfile.native -t indy-sidecar:native .
