| The execution client Geth includes a [light sync](https://github.com/ethereum/devp2p/blob/master/caps/les.md) option. However, a light Geth node relies upon full nodes serving light node data. Few full nodes opt to serve light node data, meaning light nodes often fail to find peers. There are currently no production-ready light clients on the consensus layer; however, several are in development. | ||

| There are also potential routes to providing light client data over the [gossip network](https://www.ethportal.net/. This is advantageous because the gossip network could support a network of light nodes without requiring full nodes to serve requests. |

Description
This PR adds information to the light node section of
/developers/docs/nodes-and-clients/index.md.This is part of the wiki migration. I initially expected that this might have to be a page in its own right or at least a new, expanded section in the existing landing page. However, on reflection the wiki information is execution layer specific (in fact, Geth specific), dated to 2018 and light clients have not really taken off on Ethereum yet anyway - they are something exciting for the near future. For these reasons I decided the intended outcome (overview of light clients) is best served by linking to Geth's LES protocol docs and maintaining just a short, forward looking description in the existing light nodes section on the landing page.
