+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+

+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community

+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a

+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or

+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at skylot@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is

-### Building jadx from source
+### Build from source
 JDK 8 or higher must be installed:
-
-    git clone https://github.com/skylot/jadx.git

+```
+git clone https://github.com/skylot/jadx.git
+cd jadx
+./gradlew dist

 (on Windows, use `gradlew.bat` instead of `./gradlew`)
 
 Scripts for run jadx will be placed in `build/jadx/bin`
 and also packed to `build/jadx-<version>.zip`

 Example:
  jadx -d out classes.dex
+ jadx --rename-flags "none" classes.dex
+ jadx --rename-flags "valid,printable" classes.dex
+ jadx --log-level error app.apk
 ```
 These options also worked on jadx-gui running from command line and override options from preferences dialog
 
 ### Troubleshooting
-##### Out of memory error:
-  - Reduce processing threads count (`-j` option)
-  - Increase maximum java heap size:
-    * command line (example for linux):
-      `JAVA_OPTS="-Xmx4G" jadx -j 1 some.apk`
-    * edit 'jadx' script (jadx.bat on Windows) and setup bigger heap size:
-      `DEFAULT_JVM_OPTS="-Xmx2500M"`
+Please check wiki page [Troubleshooting Q&A](https://github.com/skylot/jadx/wiki/Troubleshooting-Q&A)
