        Slither is a Solidity static analysis framework written in Python 3. It runs a suite of vulnerability detectors, prints visual information about contract details, and provides an API to easily write custom analyses. Slither enables developers to find vulnerabilities, enhance their code comprehension, and quickly prototype custom analyses.

        ## Features
        
        * Detects vulnerable Solidity code with low false positives
        * Identifies where the error condition occurs in the source code
        * Easily integrates into continuous integration and Truffle builds
        * Built-in 'printers' quickly report crucial contract information
        * Detector API to write custom analyses in Python
        * Ability to analyze contracts written with Solidity >= 0.4
        * Intermediate representation ([SlithIR](https://github.com/trailofbits/slither/wiki/SlithIR)) enables simple, high-precision analyses
        * Correctly parses 99.9% of all public Solidity code
        * Average execution time of less than 1 second per contract
        
        
        ## Bugs and Optimizations Detection
        
        Run Slither on a Truffle/Embark/Dapp/Etherlime application:
        ```bash
        slither .
        ```
        
        Run Slither on a single file:
        ```bash
        slither tests/uninitialized.sol
        ```
        
        For additional configuration, see the [usage](https://github.com/trailofbits/slither/wiki/Usage) documentation.
        
        Use [solc-select](https://github.com/crytic/solc-select) if your contracts require older versions of solc.

        ## How to install
        
        Slither requires Python 3.6+ and [solc](https://github.com/ethereum/solidity/), the Solidity compiler.
        
        ### Using Pip
        
        ```bash
        pip3 install slither-analyzer
        ```
        
        ### Using Git
        
        ```bash
        git clone https://github.com/crytic/slither.git && cd slither
        python3 setup.py install
        ```
        
        We recommend using an Python virtual environment, as detailed in the [Developer Installation Instructions](https://github.com/trailofbits/slither/wiki/Developer-installation), if you prefer to install Slither via git.
        
        ### Using Docker
        
        Use the [`eth-security-toolbox`](https://github.com/trailofbits/eth-security-toolbox/) docker image. It includes all of our security tools and every major version of Solidity in a single image. `/home/share` will be mounted to `/share`  in the container.
        
        ```bash
        docker pull trailofbits/eth-security-toolbox
        ```
        
        To share a directory in the container:
        
        ```bash
        docker run -it -v /home/share:/share trailofbits/eth-security-toolbox
        ```
