  1. You should follow the instruction manual on Rustle’s Github page; If you want to use a docker, you should skip this and follow the docker manual. 
  2. Prepare the NEAR Contract for Rustle to Analyse 


         3. Start analyzing by running ./rustle



        4. Check the report at audit -result/summary.csv


5. You can specify which detectors and severity groups you want to use   ./rustle -h for details.

Also, Note

Rustle can be used In the development process to scan the BNEAR contract iteratively. This would save a lot of manual effort and also mitigate part of the potential issues.  However, complications with semantics and vulnerabilities with complex logic still pose a challenge for Rustle, as locating such semantic issues requires the experts of BlockSec to conduct detailed and thorough reviews.
