-## Trying it out
+</div>
 
-Simply go to [docs.astar.network](https://docs.astar.network) and follow the 
-[installation](https://docs.astar.network/build/smart-contracts) instructions. You can 
-also try out one of the [core features](https://docs.astar.network/learn/core-features).
+Astar Network is an interoperable blockchain based the Substrate framework and the hub for dApps within the Polkadot Ecosystem.
+With Astar Network and Shiden Network, people can stake their tokens to a Smart Contract for rewarding projects that provide value to the network.
 
-## Contributing
+For contributing to this project, please read our [Contribution Guideline](./CONTRIBUTING.md).
 
-Currently, we have 2 production networks:
+## Building From Source
 
-- [Astar Network](https://astar.network/): formerly known as Plasm Network, and our future Parachain on Polkadot Network
-- [Shiden Network](https://shiden.astar.network/): Parachain of Kusama Network and our canary release for Astar Network
+> This section assumes that the developer is running on either macOS or Debian-variant operating system. For Windows, although there are ways to run it, we recommend using [WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10) or from a virtual machine for stability.
 
-And 2 test networks:
+Execute the following command from your terminal to set up the development environment and build the node runtime.
 
-- [Dusty Network](https://github.com/PlasmNetwork/Astar/tree/development/dusty): an independent test network with the latest cutting edge features before it is introduced to Astar Network
-- [Shibuya Network](https://github.com/PlasmNetwork/Astar/tree/development/shibuya): a Parachain test network with the latest cutting edge features related to XMCP, collators, and other cross chain operations that is planned to be rolled out to Shiden Network
+```bash
+# install Substrate development environment via the automatic script
+$ curl https://getsubstrate.io -sSf | bash -s -- --fast
 
-In the future we will gradually change this structure to have a single test network.
-For details, please read the [Contribution Guidelines](./CONTRIBUTING.md).
+# clone the Git repository
+$ git clone --recurse-submodules https://github.com/PlasmNetwork/Astar.git
 
-If you would like to be the validator, please check out [our tutorial](https://docs.astar.network/build/validator-guide) and join [Discord tech channel](https://discord.gg/wUcQt3R).
+# change current working directory
+$ cd Astar
 
-## LICENSE
+# compile the node
+# note: you may encounter some errors if `wasm32-unknown-unknown` is not installed, or if the toolchain channel is outdated
+$ cargo build --release
 
-Astar is licensed under the GPLv3.0 by Stake Technologies Inc.
+# show list of available commands
+$ ./target/release/astar-collator --help
+```
+
+### Building with Nix
+
+```bash
+# install Nix package manager:
+$ curl https://nixos.org/nix/install | sh
+
+# run from root of the project folder (`Astar/` folder)
+$ nix-shell -I nixpkgs=channel:nixos-21.05 third-party/nix/shell.nix --run "cargo build --release"
+```
+
+## Running a Collator Node
+
+To set up a collator node, you must have a fully synced node with the proper arguments, which can be done with the following command.
+
+```bash
+# start the Shiden collator node with
+$ ./target/release/astar-collator \
+  --base-path <path to save blocks> \
+  --name <node display name> \
+  --port 30333 \
+  --ws-port 9944 \
+  --rpc-port 9933 \
+  --telemetry-url 'wss://telemetry.polkadot.io/submit/ 0' \
+  --rpc-cors all \
+  --validator
+```
+
+Now, you can obtain the node's session key by sending the following RPC payload.
+
+```bash
+# send `rotate_keys` request
+$ curl -H 'Content-Type: application/json' --data '{ "jsonrpc":"2.0", "method":"author_rotateKeys", "id":1 }' localhost:9933
+
+# should return a long string of hex, which is your session key
+{"jsonrpc":"2.0","result":"<session key in hex>","id":1}
+```
+
+After this step, you should have a validator node online with a session key for your node.
+For key management and validator rewards, consult our [validator guide online](https://docs.astar.network/build/validator-guide/configure-node).
