+
+## Installation
+
+Make sure Node is [installed on your setup](https://docs.npmjs.com/getting-started/installing-node), and that a [local `geth`/`eth` node is running](../README.md#how-to-use).
+
+```bash
+npm install remix-debug
+```
+
+## Development
+
+```bash
+var Debugger = require('remix-debug').EthDebugger
+var BreakpointManager = require('remix-debug').EthDebugger
+
+var debugger = new Debugger({
+  compilationResult: () => {
+    return compilationResult // that helps resolving source location
+  }
+})
+
+debugger.addProvider(web3, 'web3')
+debugger.switchProvider('web3')
+
+var breakPointManager = new remixCore.code.BreakpointManager(this.debugger, (sourceLocation) => {
+    // return offsetToLineColumn
+})
+debugger.setBreakpointManager(breakPointManager)
+breakPointManager.add({fileName, row})
+breakPointManager.add({fileName, row})
+
+debugger.debug(<tx_hash>)
+
+// this.traceManager.getCurrentCalledAddressAt
+
+debugger.event.register('newTraceLoaded', () => {
+  // start doing basic stuff like retrieving step details
+  debugger.traceManager.getCallStackAt(34, (error, callstack) => {})
+})
+
+debugger.callTree.register('callTreeReady', () => {
+  // start doing more complex stuff like resolvng local variables
+  breakPointManager.jumpNextBreakpoint(true)
+  
+  var storageView = debugger.storageViewAt(38, <contract address>, 
+  storageView.storageSlot(0, (error, storage) => {})
+  storageView.storageRange(error, storage) => {}) // retrieve 0 => 1000 slots
+
+  debugger.extractStateAt(23, (error, state) => {
+    debugger.decodeStateAt(23, state, (error, decodedState) => {})
+  })
+  
+  debugger.sourceLocationFromVMTraceIndex(<contract address>, 23, (error, location) => {
+    debugger.decodeLocalsAt(23, location, (error, decodedlocals) => {})
+  })
+  
+  debugger.extractLocalsAt(23, (null, locals) => {}
+```
