+# Using the Portal Network REPL Client
+
+This document explains the usage and functionality of the Portal Network REPL client script. The script initializes a Portal Network node and allows interaction with it via a REPL (Read-Eval-Print Loop) interface.
+
+## Initialization
+
+The script can be started directly and initializes a Portal Network node with a REPL interface. It binds to a specified UDP port (default: `9090`).
+
+### Start the Client
+
+```bash
+npx tsx examples/portalReplClient.ts
+```
+
+The REPL interface will start with the `portal>` prompt.
+
+### Default Options
+
+| Option    | Description                      | Default |
+|-----------|----------------------------------|---------|
+| `--port`  | Port number for the UDP binding  | `9090`  |
+
+---
+
+## Supported Networks
+
+The client supports two Portal Network types:
+- **History Network** (`0x500b`)
+- **State Network** (`0x500a`)
+
+---
+
+## REPL Commands
+
+The following commands are supported in the REPL interface:
+
+### 1. `debug`
+Set debug topics for logging.
+
+**Usage**:
+```bash
+portal> .debug <topics>
+```
+**Example**:
+```bash
+portal> .debug *Portal*,*uTP*
+```
+
+---
+
+### 2. `bootstrap`
+Bootstrap the Portal Network by connecting to default bootnodes.
+
+**Usage**:
+```bash
+portal> .bootstrap
+```
+
+---
+
+### 3. `ping`
+Send a ping to a specified network.
+
+**Usage**:
+```bash
+portal> .ping <network>
+```
+**Example**:
+```bash
+portal> .ping history
+```
+
+---
+
+### 4. `findnodes`
+Find nodes in the network by ENR and distance(s).
+
+**Usage**:
+```bash
+portal> .findnodes <network> <enr> <distances>
+```
+**Example**:
+```bash
+portal> .findnodes history enr:-... 256 512
+```
+
+---
+
+### 5. `findcontent`
+Find content by content key in the network.
+
+**Usage**:
+```bash
+portal> .findcontent <network> <enr> <contentKey>
+```
+**Example**:
+```bash
+portal> .findcontent history enr:-... 0xabc123
+```
+
+---
+
+### 6. `offer`
+Offer content to a specific network.
+
+**Usage**:
+```bash
+portal> .offer <network> <enr> <contentKey> <contentValue>
+```
+**Example**:
+```bash
+portal> .offer state enr:-... 0xabc123 "Hello World"
+```
+
+---
+
+### 7. `addENR`
+Add an ENR to the local routing table.
+
+**Usage**:
+```bash
+portal> .addENR <network> <enr>
+```
+**Example**:
+```bash
+portal> .addENR history enr:-...
+```
+
+---
+
+### 8. `status`
+Display the current status of the Portal Network node.
+
+**Usage**:
+```bash
+portal> .status
+```
+
+---
+
+## Example Workflow
+
+1. **Initialize the Portal Network node**:
+   ```bash
+   npx tsx examples/portalReplClient.ts
+   ```
+
+2. **Bootstrap the network**:
+   ```bash
+   portal> .bootstrap
+   ```
+
+3. **Send a ping to the History Network**:
+   ```bash
+   portal> .ping history
+   ```
+
+4. **Find nodes in the State Network**:
+   ```bash
+   portal> .findnodes state enr:-... 246 256
+   ```
+
+5. **Offer content to the History Network**:
+   ```bash
+   portal> .offer history enr:-... 0xkey "sample content"
+   ```
+
+6. **Check the status**:
+   ```bash
+   portal> .status
+   ```
+
+---
+
+## Notes
+
+- Replace `enr:-...` with the actual ENR (Ethereum Node Record) for the target node.
+- Use valid `contentKey` (hex strings) and `contentValue` (text strings) for `findcontent` and `offer` commands.
+- Logs can be customized using the `.debug` command with appropriate topics.

 ## Routing Table Management
 
 The Portal Network module currently supports two overlay routing tables for use with the below two subnetworks:
