-## Intro
+![Overview](https://cloud.githubusercontent.com/assets/873584/5450620/1d51831e-8543-11e4-930b-670871902425.png)
   
-A <b>W</b>eb <b>IDE</b> for Teams using Golang.
+![Goto File](https://cloud.githubusercontent.com/assets/873584/5450616/1d495da6-8543-11e4-9285-f9d9c60779ac.png)
   
-<img src="https://cloud.githubusercontent.com/assets/873584/4606377/d0ca3c2a-521b-11e4-912c-d955ab05850b.png" width="100%" />
+![Autocomplete](https://cloud.githubusercontent.com/assets/873584/5450619/1d4d5712-8543-11e4-8fe4-35dbc8348a6e.png)
 
-## Motivation
+![Theme](https://cloud.githubusercontent.com/assets/873584/5450617/1d4c0826-8543-11e4-8b86-f79a4e41550a.png)
   
-* **Team** IDE:
+![Show Expression Info](https://cloud.githubusercontent.com/assets/873584/5450618/1d4cd9f4-8543-11e4-950f-121bd3ff4a39.png)
-  * Safe and reliable: the project source code stored on the server in real time, the developer's machine crashes without losing any source code 
-  * Unified environment: server unified development environment configuration, the developer machine without any additional configuration 
-  * Out of the box: 5 minutes to setup a server then open browser to develop, debug
-  * Version Control: each developer has its own source code repository, easy sync with the trunk 
-* **Web based** IDE:
-  * Developer needs a browser only
-  * Cross-platform, even on mobile devices
-  * Easy for extensions 
-  * Easy integration with other systems
-  * For the geeks
-* A try for commercial-open source: versions customized for enterprises, close to their development work flows respectively
-* Currently more popular Go IDE has some defects or regrets: 
-  * Text editor (vim/emacs/sublime/Atom, etc.): For the Go newbie is too complex 
-  * Plug-in (goclipse, etc.): the need for the original IDE support, not professional
-  * LiteIDE: no modern user interface :p
-  * No team development experience 
-* There are a few of GO IDEs, and no one developed by Go itself, this is a nice try
   
-## Features
+![Build Error Info](https://cloud.githubusercontent.com/assets/873584/5450632/3e51cccc-8543-11e4-8ca8-8d2427aa16b8.png)
 
-* Code Highlight, Folding: Go/HTML/JavaScript/Markdown etc.
+![Cross-Compilation](https://cloud.githubusercontent.com/assets/873584/10130037/226d75fc-65f7-11e5-94e4-25ee579ca175.png)
-* Autocomplete: Go/HTML etc.
-* Format: Go/HTML/JSON etc.
-* Run & Debug: run/debug multiple processes at the same time
-* Multiplayer: a real team development experience
-* Navigation, Jump to declaration, Find usages, File search etc.
-* Shell: run command on the server
-* Git integration: git command on the web
-* Web development: Frontend devlopment (HTML/JS/CSS) all in one
-* Go tool: go get/install/fmt etc.
 
-## Architecture 
+![Playground](https://cloud.githubusercontent.com/assets/873584/21209772/449ecfd2-c2b1-11e6-9aa6-a83477d9f269.gif)

-
- * A browser tab corresponds to a Wide session
- * Execution output push via WebSocket
-
-Flow: 
- 1. Browser sends ````Build```` request
- 2. Server executes ````go build```` command via ````os/exec````<br/>
-    2.1. Generates a executable file
- 3. Browser sends ````Run```` request
- 4. Server executes the file via ````os/exec````<br/>
-    4.1. A running process<br/>
-    4.2. Execution output push via WebSocket channel
- 5. Browser renders with callback function ````ws.onmessage````
-
-### Code Assist
-
-![Code Assist](https://cloud.githubusercontent.com/assets/873584/4399135/3b80c21c-4463-11e4-8e94-7f7e8d12a4df.png)
-
- * Autocompletion
- * Find Usages
-
-Flow: 
- 1. Browser sends code assist request
- 2. Handler gets user workspace of the request with HTTP session
- 3. Server executes ````gocode````/````ide_stub````<br/>
-    3.1 Sets environment variables (e.g. ${GOPATH})<br/>
-    3.2 ````gocode```` with ````lib-path```` parameter

-## Setup from sources
-
-1. Downloads source
-2. Gets dependencies with 
-   * `go get -u`
-   * `go get -u github.com/88250/ide_stub`
-   * `go get -u github.com/nsf/gocode`
-3. Compiles wide with `go build` 
-4. Configures `conf/wide.json`
-5. Runs the executable `wide` or `wide.exe`
