+## API
+
+**Common additional parameters:**
+
+* `--ip <device-ip>` to specify your device's IP address.
+
+#### 1. Adding a DApp
+
+`status-dev-cli add-dapp [dapp]`
+
+* `dapp` — JSON containing DApp information. It is not required if your DApp contains `package.json` file. Otherwise, this map should contain `whisper-identity`, `dapp-url` and `name` fields (see the example in **Scenario** section)
+
+You can additionally specify `--dapp-port <port>` if your DApp uses port other than 8080 and you don't specify a `dapp`JSON.
+
+#### 2. Removing a DApp
+
+`status-dev-cli remove-dapp [dapp]`
+
+* `dapp` — JSON containing `whisper-identity` field. It is not required if your DApp contains `package.json` file.
+
+#### 3. Refreshing a DApp automatically
+
+`status-dev-cli watch-dapp [dappDir] [dapp]`
+
+* `dapp_dir` — dir that should be observed. Not required;
+* `dapp` — JSON containing `whisper-identity` field. It is not required if your DApp contains `package.json` file.
+
+#### 4. Switching network
+
+***Requires Status 0.9.4+ & status-dev-cli 2.2.0+!***
+
+Typically when developing DApps, a developer uses his own private chain or a simulator.
+Status inserts its own web3 object into the DApp, however, this web3 object is connected to a different network than the development one.
+This command allows to switch a network. Next time you login the network will be switched back.
+
+`status-dev-cli switch-node <url>`
+
+* `url` (required) — the network that will be used instead of `http://localhost:8545`
