 More information about the protocol can be found in the [protocol documentation](https://github.com/ldclabs/ns-protocol)
 
+## Dependencies
+
+1. **Bitcoin RPC server** with `txindex` option enabled, don't need wallet. For example, run a regtest node:
+
+```sh
+bitcoind -regtest -txindex -rpcuser=test -rpcpassword=123456 -fallbackfee=0.00001
+```
+
+2. **ScyllaDB** as a database, run it in a docker container as development environment:
+
+```sh
+sudo mkdir -p /mnt/scylla/data /mnt/scylla/commitlog /mnt/scylla/hints /mnt/scylla/view_hints
+sudo docker run --restart=always --name scylla -d -p 9042:9042 --volume /mnt/scylla:/var/lib/scylla scylladb/scylla:5.2 --smp 1 --memory 2G --developer-mode 0
+```
+
+And then import the CQL schema [https://github.com/ldclabs/ns-rs/tree/main/crates/ns-indexer/cql](https://github.com/ldclabs/ns-rs/tree/main/crates/ns-indexer/cql)
+
 ## Development
 
+### Run the indexer on local machine
+
+Build:
+```sh
+cargo build --package ns-indexer --bin ns-indexer
+```
+
+Create `.env` file from sample and edit it:
+```sh
+cp ./crates/ns-indexer/sample.env .env
+```
+
+Run:
 ```sh
-cargo run --package ns-indexer --bin ns-indexer
+./target/debug/ns-indexer
 ```
 
+### Build for production
+
+Cross compile for linux:
 ```sh
 cargo build --release --target x86_64-unknown-linux-musl --package ns-indexer --bin ns-indexer
-```
