 # Schemas
 
-The `@erc725/erc725.js` library supports a range of ERC725 specification schemas.
+The `@erc725/erc725.js` library contains a range standard [LSP ERC725 JSON schemas](https://github.com/lukso-network/LIPs/blob/main/LSPs/LSP-2-ERC725YJSONSchema.md).
 
-The below are the schema element definitions supported by and tested
-with `@erc725/erc725.js`. There are certainly more possibilities, and even several
-nonsensical or redundant possibilities which will not or may not be
-supported.
+Schemas allow erc725.js to know how to decode and encode data written in an [ERC725Y](https://eips.ethereum.org/EIPS/eip-725) smart contract.

-The most common schemas from LUKSO [LSPs](https://github.com/lukso-network/LIPs/tree/main/LSPs) are available in the [`schemas/`](https://github.com/ERC725Alliance/erc725.js/tree/develop/schemas) folder.
+The most common schemas of [LUKSO Standard Proposals](https://github.com/lukso-network/LIPs/tree/main/LSPs) are available under the [`schemas/`](https://github.com/ERC725Alliance/erc725.js/tree/develop/schemas) folder.
+
+Current provided LSPs are:
+
+```
+LSP1UniversalReceiverDelegate.json
+LSP3UniversalProfileMetadata.json
+LSP4DigitalAsset.json
+LSP4DigitalAssetLegacy.json
+LSP5ReceivedAssets.json
+LSP6KeyManager.json
+```
 
 You can import them from:
 
 ```js
 import LSP3 from '@erc725/erc725.js/schemas/LSP3UniversalProfile.json';
 import LSP5 from '@erc725/erc725.js/schemas/LSP5ReceivedAssets.json';
 // ...
+
+// Later use them on instantiation
+const myErc725Contract = new ERC725js(LSP3, address, web3.currentProvider);
 ```
