+Arthas Install
+==============
+
+## Linux/Unix/Mac
+
+You can install Arthas in one single line as:
+
+```bash
+curl -L https://alibaba.github.io/arthas/install.sh | sh
+```
+
+The command line above will download the booting script `as.sh` to the current directory and you can then start Arthas by `./as.sh`, for more help info you can use `./as.sh -h` to check the details. 
+
+By the way, you can also add the absolute path of the script `as.sh` to `$PATH` to make it available globally. 
+
+## Windows
+
+Latest Version: [![Arthas](https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square "Arthas")](http://search.maven.org/classic/#search%7Cga%7C1%7Cg%3A%22com.taobao.arthas%22%20AND%20a%3A%22arthas-packaging%22)
+
+Download the latest `bin.zip`, unzip the package and you can find the `as.bat`. For now this script will only take one argument `pid` which means you can only diagnose the local Java process. (Welcome any bat script expert to make it better :heart:)
+
+```bash
+as.bat <pid>
+```
+
+A small tip: 
+
+If you are asking for better UX, you can start the Arthas Server locally by `as.bat <pid>` and then use `./as.sh <pid>@<ip>:<por>`in another Linux/Unix/Mac machine. 
+
+
+Another tip:
+
+If in Windows, the color is not working as expect. You can try [conemu](https://sourceforge.net/projects/conemu) to get it to work. 
+
+## Manual Installation
+
+[Manual Installation](manual-install.md)
+
+## Advanced Manual Boot
+
+If you cannot boot Arthas, try to pass in all the critical options manually as the following steps:
+
+### 1. locate the java for JVM:
+- Linux/Unix/Mac: `ps aux | grep java`
+- Windows: open the Process Monitor to search java
+
+### 2. Concatenate the command
+Let's suppose we are using `/opt/jdk1.8/bin/java`, then the command should be:
+
+```bash
+ /opt/jdk1.8/bin/java -Xbootclasspath/a:/opt/jdk1.8/lib/tools.jar \
+     -jar /tmp/arthas-packaging/arthas-core.jar \
+     -pid 15146 \
+     -target-ip 127.0.0.1 -telnet-port 3658 -http-port 8563 \
+     -core /tmp/arthas-packaging/arthas-core.jar \
+     -agent /tmp/arthas-packaging/arthas/arthas-agent.jar
+```
+
+    * `-Xbootclasspath` add tools.jar
+    * `-jar /tmp/arthas-packaging/arthas-core.jar` specify main entry
+    * `-pid 15146` specify the target java process pid
+    * `-target-ip 127.0.0.1` specify the IP
+    * `-telnet-port 3658 -http-port 8563` specify telnet and http ports
+    * `-core /tmp/arthas-packaging/arthas-core.jar -agent /tmp/arthas-packaging/arthas/arthas-agent.jar` specify core/agent jar package
+
+
+But if you are using JDK 1.9 or above，then you do not need to add `tools.jar` in option `-Xbootclasspath`.
+
+F.Y.I the booting log will be printed to `~/logs/arthas/arthas.log`.
+
+### 3. Connect via telnet
+
+When attached successfully, you can connect it with 
+
+```bash
+telnet localhost 3658
+```
