 A canister demonstrating how to receive ICP tokens by generating account identifiers and checking balances on the ICP ledger.
 
-This canister can be deployed on [ICP Ninja](https://icp.ninja/projects/receive-icp) for quick testing and demonstration.
+The canister exposes methods to compute account identifiers (including subaccounts based on arbitrary 128-bit upper/lower values) and to query balances from the ledger canister. This makes it easy to give each user or purpose a distinct deposit address while keeping all ICP under one canister's control.
+
+## Environment configuration
+
+The ICP ledger canister ID is configured via `icp.yaml` and read at runtime as a canister environment variable via `ic_cdk::api::env_var_value("ICP_LEDGER_CANISTER_ID")`:
+
+| Environment | Ledger | Canister ID |
+|---|---|---|
+| `local` | ICP ledger (pre-deployed by icp-cli) | `ryjl3-tyaaa-aaaaa-aaaba-cai` |
+| `staging` | TESTICP ledger | `xafvr-biaaa-aaaai-aql5q-cai` |
+| `production` | ICP ledger (mainnet) | `ryjl3-tyaaa-aaaaa-aaaba-cai` |
+
+The local environment uses the same principal as production because icp-cli's local network pre-deploys the ICP ledger at that well-known address. Staging uses the TESTICP ledger so you can test token flows without spending real ICP.
+
+## Build and deploy from the command line
+
+### Prerequisites
+
+- Node.js
+- icp-cli: `npm install -g @icp-sdk/icp-cli @icp-sdk/ic-wasm`
+
+### Install
+
+```bash
+git clone https://github.com/dfinity/examples
+cd examples/rust/receiving-icp
+```
+
+### Deploy and test locally
+
+```bash
+icp network start -d
+icp deploy
+bash test.sh
+icp network stop
+```
+
+`bash test.sh` runs 7 tests: account identifier format, subaccount uniqueness, funding the main account and a specific subaccount via account ID hex, balance queries, and subaccount independence. Tests are delta-based and idempotent across re-runs.
+
+### Deploy to staging or production
+
+```bash
+# Staging — targets the TESTICP ledger
+icp deploy --environment staging
+
+# Production — targets the mainnet ICP ledger
+icp deploy --environment production
+```
+
+## Security considerations and best practices
+
+Refer to the [security best practices](https://docs.internetcomputer.org/guides/security/overview) for information on security and best practices for your ICP app.
