-# `remix-debugger`
-
-The Remix Debugger is a webapp to debug the Ethereum VM and transactions.
-
-+ [Installation](#installation)
-+ [Development](#development)
-+ [First steps](#firststeps)
-+ [Tests](#tests)
-
-## 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
-git clone https://github.com/ethereum/remix
-cd remix/remix-debugger
-npm install
-```
-
-This will build the debugger. Start it by opening `index.html` in your browser.
-
-## Development
-
-Run `npm run start_dev` to start a local webserver, accessible at `http://127.0.0.1:8080`. Your browser will reload when files are updated.
-
-## <a name="firststeps"></a>First steps
-
-Once Remix is connected to a node, you will be able to debug transactions.
-
-You can do that:
- - using a block number and a transaction index.
- - using a transaction hash.
-
-After loading the transaction succeeded, the hash, from and to field will show up. The VM trace is then loaded.
-
-The debugger itself contains several controls that allow stepping over the trace and seing the current state of a selected step:
-
-#### Slider and Stepping action
-
-The slider allows to move quickly from a state to another.
-
-Stepping actions are:
-- Step Into Back
-- Step Over Back
-- Step Over Forward
-- Step Into Forward
-- Jump Next Call: this will select the next state that refers to a context changes - CALL, CALLCODE, DELEGATECALL, CREATE.
-
-#### State Viewer
-
-The upper right panel contains basic informations about the current step:
-- VMTraceStep: the index in the trace of the current step.
-- Step
-- Add memory
-- Gas: gas used by this step
-- Remaining gas: gas left
-- Loaded address: the current code loaded, refers to the executing code.
-
-The other 6 panels describe the current selected state:
- - Instructions list: list of all the instruction that defines the current executing code.
- - Stack
- - Storage Changes
- - Memory
- - Call Data$
- - Call Stack
-
-## Tests
-
-* To run unit tests, run `npm test`.
-
-* For local headless browser tests:
-  * To install `selenium`: `npm run selenium-install`
-  * Every time you want to run local browser tests, run: `npm run test-browser`
