-As usual, use the same `datadir` and `private.api.addr` for both Erigon and RPC. Explicitly specify the chain and the other ports to make things clearer. Quote your path if it has spaces.

 ### JSON-RPC daemon
 
-In Erigon RPC calls are extracted out of the main binary into a separate daemon. This daemon can use both local or
-remote DBs. That means, that this RPC daemon doesn't have to be running on the same machine as the main Erigon binary or
-it can run from a snapshot of a database for read-only calls.
-
-<code>🔬 See [RPC-Daemon docs](./cmd/rpcdaemon/README.md)</code>
+Most of Erigon's components can work inside Erigon and as independent process. 
 
-#### **For local DB**
+To enable built-in RPC server: `--http` and `--ws` (sharing same port with http)
 
-This is only possible if RPC daemon runs on the same computer as Erigon. This mode uses shared memory access to the
-database of Erigon, which has better performance than accessing via TPC socket (see "For remote DB" section below).
-Provide both `--datadir` and `--private.api.addr` options:
-
-```sh
-make erigon
-./build/bin/erigon --private.api.addr=localhost:9090
-make rpcdaemon
-./build/bin/rpcdaemon --datadir=<your_data_dir> --private.api.addr=localhost:9090 --http.api=eth,erigon,web3,net,debug,trace,txpool
