If you're using Anchor (which I recommend), you can use fetch to decode account data easily.

If you're not using Anchor you need to specify the structure and decode it using something like borsh.

Here is an example

const schema = new Map([[Test, { kind: 'struct', fields: [['x', 'u8'], ['y', 'u64'], ['z', 'string'], ['q', [3]]] }]]);

const newValue = borsh.deserialize(schema, decoded, buffer);
