 # Dora on Arceos
 
+* Dora
+	* For host: https://github.com/arceos-org/dora/tree/modify_spawn
+	* For ArceOS: https://github.com/arceos-org/dora/tree/arceos-porting
+* ArceOS
+	* https://github.com/arceos-org/arceos/tree/dora-wip
+
+## 1. Setup Dora coordinator and daemon on host
+
+* In dora repo under `modify_spawn` branch
 
-* on dora repo
 ```bash
+# Build.
+cargo build --release --all
+
+# Run coordinator.
 ./target/release/dora coordinator
-DORA_NODE_CONFIG_PATH=`pwd` ./target/release/dora daemon
 
+# Run daemon.
+DORA_NODE_CONFIG_PATH=`pwd` ./target/release/dora daemon
 ```
 
-* on dora-benchmark
+## 2. Generate configuration file for Dora nodes.
+
+* In dora-benchmark repo:  `/dora-benchmark/dora-rs/rs-latency`
 ```bash
-./PATH/TO/dora start dataflow.yml
+./PATH/TO/dora/you/just/compiled start dataflow.yml
 ```
 
 * then you can get `rust-node.yml` and `rust-sink.yml` on dora repo.
 
-* dora nodes on host
+## 3. Boot Dora nodes based on these configuration file.
+
+### To boot Dora nodes on host
 ```bash
+# Build.
+cargo build --release --all
+
+# Run nodes.
 DORA_NODE_CONFIG=`cat rust-node.yml` ./target/release/benchmark-example-node
 DORA_NODE_CONFIG=`cat rust-sink.yml` ./target/release/benchmark-example-sink
 ```
 
-*dora nodes on ArceOS
+### To boot Dora nodes upon ArceOS
+
+In ArceOS dir under `dora-wip` branch.
+
+Pay attention to `dora-node-api` dependency,
+this is just the `arceos-porting` branch of Dora repo,
+We have separated their dirs to facilitate the compilation of Dora in the host and Dora dependencies for ArceOS std.
+
+```Toml
+[workspace.dependencies]
+# dora-node-api = "0.3.5" # { path = "../../../dora/apis/rust/node" }
+dora-node-api = { path = "../../Dora/dora-arceos/apis/rust/node" }
+```
+
+* Run ArceOS on QEMU/KVM
+	* make `disk.img` for ArceOS, make sure it contains the configuration files just generated for the Dora nodes.
+	* change `socket_addr` to : `socket_addr: "10.0.2.2:44631"` in configuration files.
+
 ```bash
 # make sure sink.yml in your disk.img
 make A=apps/std/dora/sink SMP=1 NET=y BLK=y LOG=debug STD=y build
