+A collection of TypeScript + JavaScript tools and libraries for DeFiChain developers to build decentralized finance on Bitcoin.
+Consisting of 4 packages with more to be added in the future, the jellyfish project allow DeFiChain developers to build decentralized apps that are modern, easy to use and easy to test.
+
+Jellyfish follows a monorepo methodology, all maintained packages are in the same repo and published with the same version tag.
+
+## Packages
+
+* `@defichain/jellyfish` bundled usage entrypoint with conventional defaults for 4 bundles: umd, esm, cjs
+  and d.ts
+* `@defichain/jellyfish-core` is a protocol agnostic DeFiChain client interfaces, with a "foreign function interface"
+  design.
+* `@defichain/jellyfish-jsonrpc` implements the [JSON-RPC 1.0](https://www.jsonrpc.org/specification_v1) specification.
+* `@defichain/testcontainers` provides a lightweight, throw away instances for DeFiD node provisioned automatically in
+  Docker container.

+## Conventional defaults
+
+`@defichain/jellyfish` package provides conventional defaults and bundle all code required for dApps building. 
+
+```js
+import { Client, HttpProvider } from '@defichain/jellyfish'
+
+// Coventional Defaults
+let client = new Client()
+
+// Explicit Configuration
+client = new Client(new HttpProvider('http://foo:bar@localhost:8554'), {
+    timeout: 30000
+})
+```
+
+## Promise-based client
+
+To prevent a "callback hell" structure where code get nested and messy; making it harder to understand.
+A `Promise<?>` based design is used as async/await implementation are very mature today, it brings better quality of 
+life to modern development.
+
+```js
+import {Client} from '@defichain/jellyfish'
+
+const client = new Client()
+const {blocks} = await client.mining.getMintingInfo()
+```
+
+## IEEE-754 arbitrary precision
+
+Due to the dynamic nature of the JavaScript language, it forces all number to be interpolated as IEEE-754 which can 
+cause precision to be lost. [DeFiCh/jellyfish/issues/18](https://github.com/DeFiCh/jellyfish/issues/18)
+
+```js
+it('lost precision converting DFI 😥', () => {
+  const n = 1200000000.00000001
+  const a = JSON.parse(JSON.stringify(n)) * 1.0e8
+  expect(a.toString()).toBe("120000000000000001")
+});
+```
+
+### `JellyfishJSON`
+
+**jellyfish-core** implements `JellyfishJSON` that allows parsing of JSON with `'lossless'`, `'bignumber'` and 
+`'number'` numeric precision.
+
+* **'lossless'** uses LosslessJSON that parses numeric values as LosslessNumber. With LosslessNumber, one can perform
+  regular numeric operations, and it will throw an error when this would result in losing information.
+* **'bignumber'** parse all numeric values as 'BigNumber' using bignumber.js library.
+* **'number'** parse all numeric values as 'Number' and precision will be loss if it exceeds IEEE-754 standard.
+
+
+As not all number parsed are significant in all context, (e.g. `mining.getMintingInfo()`), this allows jellyfish library 
+users to use the `number` for non precision sensitive operation (e.g. `networkhashps`) and BigNumber for precision 
+sensitive operations.
+
+### `JellyfishClient`
+
+As jellyfish is written in TypeScript, all RPC exchanges with a node are typed. BigNumber precision is used for all 
+wallet or transaction related operations. While IEEE-754 number is used for all other arbitrary operations.
+
+```ts {3}
+export class Wallet {
+  async getBalance (minimumConfirmation: number = 0, includeWatchOnly: boolean = false): Promise<BigNumber> {
+    return await this.client.call('getbalance', ['*', minimumConfirmation, includeWatchOnly], 'bignumber')
+  }
+}
+
+```
+
+```ts {2-3,9,13}
+export interface MintingInfo {
+  blocks: number
+  currentblockweight?: number
+  //...
+}
+
+export class Mining {
+  async getNetworkHashPerSecond (nblocks: number = 120, height: number = -1): Promise<number> {
+    return await this.client.call('getnetworkhashps', [nblocks, height], 'number')
+  }
+
+  async getMintingInfo (): Promise<MintingInfo> {
+    return await this.client.call('getmintinginfo', [], 'number')
+  }
+}
+```
+
+## Protocol agnostic core
+
+JellyfishClient in `jellyfish-core` is a protocol agnostic DeFiChain client implementation with APIs separated into 
+their category. The protocol-agnostic core enable independent communication protocols, allowing
+vendor-agnostic middleware adaptable to any needs.
+
+```ts
+export abstract class JellyfishClient {
+  /**
+   * A promise based procedure call handling
+   *
+   * @param method Name of the RPC method
+   * @param params Array of params as RPC payload
+   * @param precision
+   * Numeric precision to parse RPC payload as 'lossless', 'bignumber' or 'number'.
+   *
+   * 'lossless' uses LosslessJSON that parses numeric values as LosslessNumber. With LosslessNumber, one can perform
+   * regular numeric operations, and it will throw an error when this would result in losing information.
+   *
+   * 'bignumber' parse all numeric values as 'BigNumber' using bignumber.js library.
+   *
+   * 'number' parse all numeric values as 'Number' and precision will be loss if it exceeds IEEE-754 standard.
+   *
+   * @throws JellyfishError
+   * @throws JellyfishRPCError
+   * @throws JellyfishClientError

+## What is jellyfish?
+
+Jellyfish is a JS library written to enable developers to develop decentralized applications on top of DeFiChain. As
+with all modern JavaScript projects, jellyfish follows a monorepo structure with its concerns separated. All packages
+maintained in this repo are published with the same version tag and follows the `DeFiCh/ain` releases.
+
+- **jellyfish** is the entrypoint for most dApps developer as it bundles and create 4 types of JavaScript modules:
+  cjs, esm, umd and d.ts.
+- **jellyfish-core** represents a protocol agnostic interface of DeFiChain client with APIs separated into their
+  category.
+- **jellyfish-jsonrpc** implements the jellyfish-core with the JSON-RPC 1.0 specification.
+
+Written in TypeScript, jellyfish provides first-class citizen support for TypeScript with strongly typed interfaces of
+DeFiChain rpc exchanges. Built using modern JavaScript approaches, it emphasises a **future-first developer experience** 
+and backport for compatibility. The protocol-agnostic core enable independent communication protocols, allowing
+vendor-agnostic middleware adaptable to any needs.
