MAN Plus is an extension for the browser that allows you to view and interact with Dapps, such as the Matrix Blockchain itself, in your browser. Once installed, it adds a button on the webpage you are viewing that opens a menu, where you can select to interact with it.

It is based on the Matrix JavaScript API and enables interaction with other Dapps. It also allows you to create and manage your own identities, so that when a Dapp wants to perform a transaction and write to the blockchain, you will be given a secure interface to review it.

The extension is required to read and write to any website. The user will be required to agree to the terms and conditions before installing the extension.

You can follow the instructions in the manual to get started.
