    # Quick Reference
    This section is a boiled down version of everything above. It should serve as an easy reference. These steps assume you've identified and installed the correct JDK.

    #### Modify and Re-Jar Extension

    1. Locate the jar file: *Extender > Extensions > Select extension > Details*. `bapps\` directory is located at `C:\Users\yourusername\AppData\Roaming\BurpSuite\bapps`
    2. Backup the original jar file to a different folder, outside of bapps.
    3. Change extension from .jar to .zip, extract contents, delete .zip file
    4. Make your modifications
    5. Re-jar: `jar cvf yourJarName.jar -C extractedContentsDirectory/ .`
    6. Reload extension in Burp: *Extender > Extensions*, uncheck Load and check it again

    #### Compile Extension from Source

    1. Clone or download extension source code
    2. Make your modifications, and create build location
    3. Compile source code: `javac -cp "C:\Program Files\BurpSuitePro\burpsuite_pro.jar" -d buildLocation sourceCodeLocation\*.java`
    4. Create Jar: `jar cvf yourJarName.jar buildLocation/*.class anyOtherDependencies1 anyOtherDependencies2`
    5. Load Jar into Burp: *Extender > Extensions*, Add, Extension type Java and locate built jar, Next, Close
    6. Disable original version of extension from BApp store
