 # Mythril
 
-Mythril is an assembler and disassembler for Ethereum VM bytecode. It was created for low-level testing/fuzzing of EVM implementations.
+Mythril is a bug hunting tool/framework the Ethereum blockchain.

 ## Usage
 
-To disassemble a piece of bytecode, pass it on the command line:
+-- TODO --
 
-```bash
+I'm currently rewriting the whole thing and the docs need to be updated.
-$ mythril -d -c "0x606060405050"
-PUSH1 0x60
-PUSH1 0x40
-POP
-POP
-```
-
-### Modifying and re-assembling code
-
-Mythril can assemble code from input files that contain one instruction per line. To start from an existing contract, save the disassembly to a text file:
-
-```bash
-$ mythril -d -c "0x606060405050" -o code.easm
-```
-
-Edit the instructions in a text editor. For example, we can modify the `PUSH` instructions from the original example:
-
-```
-PUSH2 0x4050
-PUSH4 0x60708090
-POP
-POP
-```
-
-Save the file and run Mythril with the `-a` flag to re-assemble:
-
-```
-$ mythril -a code.easm 
-0x61405063607080905050
-```
-
-The virtual machine language is described in the [Ethereum Yellowpaper](http://gavwood.com/paper.pdf).
-
-### Tracing EVM execution
-
-You can run a piece of bytecode in the [PyEthereum](https://github.com/ethereum/pyethereum) VM and trace its execution using the `-t` flag. This will output the instructions executed as well as the state of the stack for every execution step. To run code from the command line, use:
-
-```bash
-$ ./mythril.py -t -c "0x606060405050"
-vm stack=[] op=PUSH1 steps=0 pc=b'0' address=b'\x01#Eg\x89\xab\xcd\xef\x01#Eg\x89\xab\xcd\xef\x01#Eg' depth=0 pushvalue=96 gas=b'1000000' storage={'code': '0x', 'nonce': '0', 'balance': '0', 'storage': {}} inst=96
-vm stack=[b'96'] op=PUSH1 steps=1 depth=0 pushvalue=64 gas=b'999997' pc=b'2' inst=96
-vm stack=[b'96', b'64'] op=POP steps=2 depth=0 gas=b'999994' pc=b'4' inst=80
-vm stack=[b'96'] op=POP steps=3 depth=0 gas=b'999992' pc=b'5' inst=80
-```
-
-For larger contracts, you might prefer to compile them to a binary file instead:
-
-```
-$ mythril -a contract.easm -o contract.bin
-$ mythril --trace -f contract.bin
-```
-
-### Disassembling a contract from the Ethereum blockchain
-
-You can also load code from an existing contract in the Ethereum blockchain. For this, you need to have a full node running, and the RPC debug interface must be activated. For example, when running `geth` you can do this as follows:
-
-```bash
-$ geth --syncmode full --rpc --rpcapi eth,debug
-```
-
-To load contract code from your node, pass the TxID of the transaction that created the contract:
-
-```bash
-$ mythril -d --txid 0x23112645da9ae684270de843faaeb44918c79a09e019d3a6cf8b87041020340e -o some_contract.easm
-```
-
-Note: If you want to get code from the Ethereum mainnet, it is easier to download it from [Etherscan](https://etherscan.io).
