-# Account Compression SDK
+# `@solana/spl-account-compression`
 
-Currently contains a typescript SDK to interact with on-chain SPL ConcurrentMerkleTrees.
+A TypeScript library for interacting with SPL Account Compression and SPL NoOp.
 
-Used to test Account Compression program.
+## Install
 
-# Setting up the Solita-based Typescript SDK
+```shell
+npm install --save @solana/spl-account-compression @solana/web3.js
+```
+
+__OR__
+
+```shell
+yarn add @solana/spl-account-compression @solana/web3.js
+```
+
+
+## Examples
+
+* Solana Program Library [tests](https://github.com/solana-labs/solana-program-library/tree/master/account-compression/sdk/tests)
+
+* Metaplex Program Library Compressed NFT [tests](https://github.com/metaplex-foundation/metaplex-program-library/tree/master/bubblegum/js/tests)
+
+## Information
+
+This on-chain program provides an interface for composing smart-contracts to create and use SPL ConcurrentMerkleTrees. The primary application of using SPL ConcurrentMerkleTrees is to make edits to off-chain data with on-chain verification.
+
+This program is targeted towards supporting [Metaplex Compressed NFTs](https://github.com/metaplex-foundation/metaplex-program-library/tree/master/bubblegum) and may be subject to change.
+
+Note: Using this program requires an indexer to parse transaction information and write relevant information to an off-chain database.
+
+A **rough draft** of the whitepaper for SPL ConcurrentMerkleTree's can be found [here](https://drive.google.com/file/d/1BOpa5OFmara50fTvL0VIVYjtg-qzHCVc/view).
+
+## Build from Source
+
+0. Install dependencies with `yarn`.
 
 1. Generate the Solita SDK with `yarn solita`.
 
 2. Then build the SDK with `yarn build`.
 
-# Testing the SDK
-
-Run `yarn test`. Expect `jest` to detect an open handle that prevents it from exiting tests naturally.
+3. Run tests with `yarn test`. (Expect `jest` to detect an open handle that prevents it from exiting naturally)
