Furthermore we are organizing issues in [milestones](https://github.com/paritytech/parity-ethereum/milestones). Best way to get started is to a pick a ticket from the current milestone tagged [`easy`](https://github.com/paritytech/parity-ethereum/labels/Q2-easy%20%F0%9F%92%83) and get going, or [`mentor`](https://github.com/paritytech/parity-ethereum/labels/Q1-mentor%20%F0%9F%95%BA) and get in contact with the mentor offering their support on that larger task.

 ### Rules

 * **No pushing directly to the master branch**.
 * **All modifications** must be made in a **pull-request** to solicit feedback from other contributors.
 * Pull-requests cannot be merged before CI runs green and two reviewers have given their approval.
-* Contributors should adhere to the [Parity Ethereum Style Guide](https://wiki.parity.io/Parity-Ethereum-Style-Guide).
+* All code changed should be formated by running `cargo fmt -- --config=merge_imports=true`
 
 ### Recommendations
 
-* **Non-master branch names** *should* be prefixed with a short name moniker, followed by the associated Github Issue ID (if any), and a brief description of the task using the format `<GITHUB_USERNAME>-<ISSUE_ID>-<BRIEF_DESCRIPTION>` (e.g. `gavin-123-readme`). The name moniker helps people to inquiry about their unfinished work, and the GitHub Issue ID helps your future self and other developers (particularly those who are onboarding) find out about and understand the original scope of the task, and where it fits into Parity Ethereum [Projects](https://github.com/paritytech/parity-ethereum/projects).

-# Security Policy
-
-Parity Technologies is committed to resolving security vulnerabilities in our software quickly and carefully. We take the necessary steps to minimize risk, provide timely information, and deliver vulnerability fixes and mitigations required to address security issues.
-
-## Reporting a Vulnerability
-
-Security vulnerabilities in Parity software should be reported by email to security@parity.io. If you think your report might be eligible for the Parity Bug Bounty Program, your email should be send to bugbounty@parity.io. 
-
-Your report should include the following:
-
-- your name
-- description of the vulnerability
-- attack scenario (if any)
-- components
-- reproduction
-- other details
-
-Try to include as much information in your report as you can, including a description of the vulnerability, its potential impact, and steps for reproducing it. Be sure to use a descriptive subject line.
-
-You'll receive a response to your email within two business days indicating the next steps in handling your report. We encourage finders to use encrypted communication channels to protect the confidentiality of vulnerability reports. You can encrypt your report using our public key. This key is [on MIT's key server](https://pgp.mit.edu/pks/lookup?op=get&search=0x5D0F03018D07DE73) server and reproduced below.
-
-After the initial reply to your report, our team will endeavor to keep you informed of the progress being made towards a fix. These updates will be sent at least every five business days. 
-
-Thank you for taking the time to responsibly disclose any vulnerabilities you find.
-
-## Responsible Investigation and Reporting
-
-Responsible investigation and reporting includes, but isn't limited to, the following:
-
-- Don't violate the privacy of other users, destroy data, etc.
-- Don’t defraud or harm Parity Technologies Ltd or its users during your research; you should make a good faith effort to not interrupt or degrade our services.
-- Don't target our physical security measures, or attempt to use social engineering, spam, distributed denial of service (DDOS) attacks, etc.
-- Initially report the bug only to us and not to anyone else.
-- Give us a reasonable amount of time to fix the bug before disclosing it to anyone else, and give us adequate written warning before disclosing it to anyone else.
-- In general, please investigate and report bugs in a way that makes a reasonable, good faith effort not to be disruptive or harmful to us or our users. Otherwise your actions might be interpreted as an attack rather than an effort to be helpful.
-
-## Bug Bounty Program
-
-Our Bug Bounty Program allows us to recognise and reward members of the Parity community for helping us find and address significant bugs, in accordance with the terms of the Parity Bug Bounty Program. A detailed description on eligibility, rewards, legal information and terms & conditions for contributors can be found on [our website](https://paritytech.io/bug-bounty.html).

-Parity Ethereum keys generator.
-  Copyright 2015-2019 Parity Technologies (UK) Ltd.
-
-Usage:
-    ethkey info <secret-or-phrase> [options]
-    ethkey generate random [options]
-    ethkey generate prefix <prefix> [options]
-    ethkey sign <secret> <message>
-    ethkey verify public <public> <signature> <message>
-    ethkey verify address <address> <signature> <message>
-    ethkey recover <address> <known-phrase>
-    ethkey [-h | --help]
-
-Options:
-    -h, --help         Display this message and exit.
-    -s, --secret       Display only the secret key.
-    -p, --public       Display only the public key.
-    -a, --address      Display only the address.
-    -b, --brain        Use parity brain wallet algorithm. Not recommended.
-
-Commands:
-    info               Display public key and address of the secret.
-    generate random    Generates new random Ethereum key.
-    generate prefix    Random generation, but address must start with a prefix ("vanity address").
-    sign               Sign message using a secret key.
-    verify             Verify signer of the signature by public key or address.
-    recover            Try to find brain phrase matching given address from partial phrase.

+
+EVM implementation for OpenEthereum.
+
+### Usage
+
+```
+EVM implementation for Parity.
+  Copyright 2015-2020 Parity Technologies (UK) Ltd.
+
+Usage:
+    openethereum-evm state-test <file> [--json --std-json --std-dump-json --only NAME --chain CHAIN --std-out-only --std-err-only --omit-storage-output --omit-memory-output]
+    openethereum-evm stats [options]
+    openethereum-evm stats-jsontests-vm <file>
+    openethereum-evm [options]
+    openethereum-evm [-h | --help]
+
+Commands:
+    state-test         Run a state test from a json file.
+    stats              Execute EVM runtime code and return the statistics.
+    stats-jsontests-vm Execute standard json-tests format VMTests and return
+                       timing statistics in tsv format.
+
+Transaction options:
+    --code CODE        Contract code as hex (without 0x).
+    --to ADDRESS       Recipient address (without 0x).
+    --from ADDRESS     Sender address (without 0x).
+    --input DATA       Input data as hex (without 0x).
+    --gas GAS          Supplied gas as hex (without 0x).
+    --gas-price WEI    Supplied gas price as hex (without 0x).
+
+State test options:
+    --chain CHAIN      Run only from specific chain name (i.e. one of EIP150, EIP158,
+                       Frontier, Homestead, Byzantium, Constantinople,
+                       ConstantinopleFix, Istanbul, EIP158ToByzantiumAt5, FrontierToHomesteadAt5,
+                       HomesteadToDaoAt5, HomesteadToEIP150At5, Berlin, Yolo3).
+    --only NAME        Runs only a single test matching the name.
+
+General options:
+    --json                    Display verbose results in JSON.
+    --std-json                Display results in standardized JSON format.
+    --std-err-only            With --std-json redirect to err output only.
+    --std-out-only            With --std-json redirect to out output only.
+    --omit-storage-output     With --std-json omit storage output.
+    --omit-memory-output      With --std-json omit memory output.
+    --std-dump-json           Display results in standardized JSON format
+                              with additional state dump.
+
+Display result state dump in standardized JSON format.
+    --chain CHAIN      Chain spec file path.
+    -h, --help         Display this message and exit.
