-## MultisSig Contracts
-
-MultiSig smart contracts
-
-## Usage
-
-Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
-
--   [multisig](./contracts/multisig)
-    -   This directory contains the [Gnosis MultiSigWallet](https://github.com/gnosis/MultiSigWallet) and a custom extension that adds a timelock to transactions within the MultiSigWallet.
--   [test](./contracts/test)
-    -   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
-
-## Contributing
-
-We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
-
-For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
-
-Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
-
-### Install Dependencies
-
-If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
-
-```bash
-yarn config set workspaces-experimental true
-```
-
-Then install dependencies
-
-```bash
-yarn install
-```
-
-### Build
-
-To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
-
-```bash
-PKG=@0x/contracts-multisig yarn build
-```
-
-Or continuously rebuild on change:
-
-```bash
-PKG=@0x/contracts-multisig yarn watch
-```
-
-### Clean
-
-```bash
-yarn clean
-```
-
-### Lint
-
-```bash
-yarn lint
-```
-
-### Run Tests
-
-```bash
-yarn test
-```
-
-#### Testing options
-
-Contracts testing options like coverage, profiling, revert traces or backing node choosing - are described [here](../TESTING.md).
