+Developer Notes
+===
+
+## Preparing for running the code
+
+**Notice:** *There's [specialised instructions for docker](../setup/docker.md) or [heroku](../setup/heroku.md), if you prefer running code this way!*
+
+1. Clone the repository with `git clone https://github.com/codimd/server.git codimd-server`
+   (cloning is the preferred way, but you can also download and unzip a release)
+2. Enter the directory and run `bin/setup`, which will install npm dependencies
+   and create configs. The setup script is written in Bash, you would need bash
+   as a prerequisite.
+3. Setup the [config file](../configuration-config-file.md) or set up
+   [environment variables](../configuration-env-vars.md).
+
+
+## Running the Code
+
+Now that everything is in place, we can start CodiMD:
+
+4. `npm run build` will build the frontend bundle. It uses webpack to do that.
+5. Run the server with `node app.js`
+
+
+## Running the Code with Auto-Reload
+
+The commands above are fine for production, but you're a developer and surely
+you want to change things. You would need to restart both commands whenever you
+change something. Luckily, you can run these commands that will automatically
+rebuild the frontend or restart the server if necessary.
+
+The commands will stay active in your terminal, so you will need multiple tabs
+to run both at the same time.
+
+4. Use `npm run dev` if you want webpack to continuously rebuild the frontend
+   code.
+5. To auto-reload the server, the easiest method is to install [nodemon](https://www.npmjs.com/package/nodemon)
+   and run `nodemon --watch app.js --watch lib --watch locales app.js`.
+
+
+## Structure
+
+The repository contains two parts: a server (backend) and a client (frontend).
+most of the server code is in `/lib` and most of the client code is in `public`.

+Operational Transformation
+===
+
+From 0.3.2, we started supporting operational transformation.
+It makes concurrent editing safe and will not break up other users' operations.
+Additionally, now can show other clients' selections.

+Webpack
+===
+
+Webpack is a JavaScript build system for frontend code. You can find out all
+about it on [the webpack website](https://webpack.js.org/).
+
+Here's how we're using it:
+
 ## `webpack.common.js`
