+## Avalanche RPC Proxy and Caching
+
+[eRPC](https://github.com/erpc/erpc) is a fault-tolerant EVM RPC proxy and re-org aware permanent caching solution. It is built with read-heavy use-cases in mind such as data indexing and high-load frontend usage.
+
+# Quickstart
+
+1. Create your [`erpc.yaml`](https://docs.erpc.cloud/config/example) configuration file:
+
+```yaml filename="erpc.yaml"
+logLevel: debug
+projects:
+  - id: main
+    upstreams:
+      # You don't need to define architecture (e.g. evm) or chain id (e.g. 43114)
+      # as they will be detected automatically by eRPC.
+      - endpoint: https://ava-mainnet.blastapi.io/xxxx
+      - endpoint: evm+alchemy://xxxx-my-alchemy-api-key-xxxx
+```
+
+See [a complete config example](https://docs.erpc.cloud/config/example) for inspiration.
+
+2. Use the Docker image:
+
+```bash
+docker run -v $(pwd)/erpc.yaml:/root/erpc.yaml -p 4000:4000 -p 4001:4001 ghcr.io/erpc/erpc:latest
+```
+
+3. Send your first request:
+
+```bash
+curl --location 'http://localhost:4000/main/evm/43114' \
+--header 'Content-Type: application/json' \
+--data '{
+    "method": "eth_getBlockByNumber",
+    "params": [
+        "0x2e76572",
+        false
+    ],
+    "id": 9199,
+    "jsonrpc": "2.0"
+}'
+```
+
+4. Bring up monitoring stack (Prometheus, Grafana) using docker-compose:
+
+```bash
+# clone the repo if you haven't
+git clone https://github.com/erpc/erpc.git
+cd erpc
+
+# bring up the monitoring stack
+docker-compose up -d
+```
+
+5. Open Grafana at [http://localhost:3000](http://localhost:3000) and login with the following credentials:
+
+- username: `admin`
+- password: `admin`
+
+6. Send more requests and watch the metrics being collected and visualized in Grafana.
