 ## @0x/asset-buyer
 
-**Warning: In Beta, has not been extensively tested.**
-
 Convenience package for buying assets represented on the Ethereum blockchain using 0x. In its simplest form, the package helps in the usage of the [0x forwarder contract](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md), which allows users to execute [Wrapped Ether](https://weth.io/) based 0x orders without having to set allowances, wrap Ether or own ZRX, meaning they can buy tokens with Ether alone. Given some liquidity (0x signed orders), it helps estimate the Ether cost of buying a certain asset (giving a range) and then buying that asset.
 
 In its more advanced and useful form, it integrates with the [Standard Relayer API](https://github.com/0xProject/standard-relayer-api) and takes care of sourcing liquidity for you given an SRA compliant endpoint. The final result is a library that tells you what assets are available, provides an Ether based quote for any asset desired, and allows you to buy that asset using Ether alone.

+### Publish
+
+#### 0x Ganache Snapshot
+
+The 0x Ganache snapshot can be generated and published in this package. In order to build the snapshot for this version of migrations run:
+
+```bash
+yarn build:snapshot
+```
+
+This will run the migrations in Ganache and output a zip file to be uploaded to the s3 bucket. For example, after running this command you will have created `0x_ganache_snapshot-2.2.2.zip`. To publish the zip file to the s3 bucket run:
+
+```bash
+yarn publish:snapshot
+```
+
+This snapshot will now be publicly available at http://ganache-snapshots.0x.org.s3.amazonaws.com/0x_ganache_snapshot-latest.zip and also versioned with the package.json version.
+
+#### 0x Ganache Docker Image
+
+We also publish a simple docker image which downloads the latest snapshot, extracts and runs Ganache. This is not required to be built when migrations change as it always downloads and runs the latest zip file. If you have made changes to the Dockerfile then a publish of the image is required. To do this run:
+
+```bash
+yarn build:snapshot:docker
+yarn publish:snapshot:docker
+```
+
+The result is a published docker image to the 0xorg docker registry. To start the docker image run:
+
+```bash
+docker run -p 8545:8545 -ti 0xorg/ganache-cli:latest
+```
+
+This will pull the latest zip in the s3 bucket, extract and start Ganache with the snapshot.
+
+In the event you need a specific version of the published Ganache snapshot run the following specifying the VERSION environment variable:
+
+```bash
+docker run -e VERSION=2.2.2 -p 8545:8545 -ti 0xorg/ganache-cli:latest
+```

 With the connection established, you prepare the payload for your request. The payload is a json object with a format established by the [JSON RPC specification](https://www.jsonrpc.org/specification):
 
-*   `id`: All requests require you to specify a numerical `id`. When the server responds to the request, the response will have the same `id` as the one supplied with your request.
-*   `jsonrpc`: This is always the string `'2.0'`.
-*   `method`: This specifies the OrderWatcher method you want to call. I.e., `'ADD_ORDER'`, `'REMOVE_ORDER'` or `'GET_STATS'`.
-*   `params`: These contain the parameters needed by OrderWatcher to execute the method you called. For `ADD_ORDER`, provide `{ signedOrder: <your signedOrder> }`. For `REMOVE_ORDER`, provide `{ orderHash: <your orderHash> }`. For `GET_STATS`, no parameters are needed, so you may leave this empty.

 **Response**
 The server responds to all requests in a similar format. In the data field, you'll find another object containing the following fields:
 
-*   `id`: The id corresponding to the request that the server is responding to. `UPDATE` responses are not based on any requests so the `id` field is omitted`.
-*   `jsonrpc`: Always `'2.0'`.
-*   `method`: The method the server is responding to. Eg. `ADD_ORDER`. When order states change the server may also initiate a response. In this case, method will be listed as `UPDATE`.
-*   `result`: This field varies based on the method. `UPDATE` responses contain the new order state. `GET_STATS` responses contain the current order count. When there are errors, this field is omitted.

 Sol-compiler is a wrapper around [solc-js](https://www.npmjs.com/package/solc) that adds:
 
-*   Smart re-compilation: Only recompiles when smart contracts have changed
-*   Ability to compile an entire project instead of only individual `.sol` files
-*   Compilation using the Solidity version specified at the top of each individual `.sol` file
-*   Proper parsing of Solidity version ranges
-*   Support for the standard [input description](https://solidity.readthedocs.io/en/develop/using-the-compiler.html#input-description) for what information you'd like added to the resulting `artifacts` file (i.e 100% configurable artifacts content).

-*   All token amounts are sent in amounts of the smallest level of precision (base units). (e.g if a token has 18 decimal places, selling 1 token would show up as selling `'1000000000000000000'` units by this API).
-*   All addresses are sent as lower-case (non-checksummed) Ethereum addresses with the `0x` prefix.
-*   All parameters are to be written in `lowerCamelCase`.

 Welcome to the [sol-compiler](https://github.com/0xProject/0x-monorepo/tree/development/packages/sol-compiler) documentation! Sol-compiler is a wrapper around [solc-js](https://www.npmjs.com/package/solc) that adds:
 
-*   Smart re-compilation: Only recompiles when smart contracts have changed
-*   Ability to compile an entire project instead of only individual `.sol` files
-*   Compilation using the Solidity version specified at the top of each individual `.sol` file
-*   Proper parsing of Solidity version ranges
-*   Support for the standard [input description](https://solidity.readthedocs.io/en/develop/using-the-compiler.html#input-description) for what information you'd like added to the resulting `artifacts` file (i.e 100% configurable artifacts content).
-*   Storage of constructor args, source maps and paths to all dependency source files.

+Sol-trace uses transaction traces in order to figure out which lines of Solidity source code have been covered by your tests. In order for it to gather these traces, you must add the `TraceSubprovider` to the [ProviderEngine](https://github.com/MetaMask/provider-engine) instance you use when running your Solidity tests. If you're unfamiliar with ProviderEngine, please read the [Web3 Provider explained](https://0x.org/wiki#Web3-Provider-Explained) wiki article.
+
+The TraceSubprovider eavesdrops on the `eth_sendTransaction` and `eth_call` RPC calls and collects traces after each call using `debug_traceTransaction`. `eth_call`'s' don't generate traces - so we take a snapshot, re-submit it as a transaction, get the trace and then revert the snapshot.
+
+Trace subprovider needs some info about your contracts (`srcMap`, `bytecode`). It gets that info from your project's artifacts. Some frameworks have their own artifact format. Some artifact formats don't actually contain all the neccessary data.
+
+In order to use `TraceSubprovider` with your favorite framework you need to pass an `artifactsAdapter` to it.
+
+### Sol-compiler
+
+If you are generating your artifacts with [@0x/sol-compiler](https://0x.org/docs/sol-compiler) you can use the `SolCompilerArtifactsAdapter` we've implemented for you.
+
+```typescript
+import { SolCompilerArtifactsAdapter } from '@0x/sol-trace';
+const artifactsPath = 'src/artifacts';
+const contractsPath = 'src/contracts';
+const artifactsAdapter = new SolCompilerArtifactsAdapter(artifactsPath, contractsPath);
+```
+
+### Truffle
+
+If your project is using [Truffle](https://truffleframework.com/), we've written a `TruffleArtifactsAdapter`for you.
+
+```typescript
+import { TruffleArtifactAdapter } from '@0x/sol-trace';
+const contractsPath = 'src/contracts';
+const artifactAdapter = new TruffleArtifactAdapter(contractsDir);
+```
+
+Because truffle artifacts don't have all the data we need - we actually will recompile your contracts under the hood. That's why you don't need to pass an `artifactsPath`.
+
+### Other framework/toolset
+
+You'll need to write your own artifacts adapter. It should extend `AbstractArtifactsAdapter`.
+Look at the code of the two adapters above for examples.
+
+### Usage
+
+```typescript
+import { TraceSubprovider } from '@0x/sol-trace';
+import ProviderEngine = require('web3-provider-engine');
+
+const provider = new ProviderEngine();
+
+const artifactsPath = 'src/artifacts';
+const contractsPath = 'src/contracts';
+const networkId = 50;
+// Some calls might not have `from` address specified. Nevertheless - transactions need to be submitted from an address with at least some funds. defaultFromAddress is the address that will be used to submit those calls as transactions from.
+const defaultFromAddress = '0x5409ed021d9299bf6814279a6a1411a7e866a631';
+const isVerbose = true;
+const traceSubprovider = new TraceSubprovider(artifactsAdapter, defaultFromAddress, isVerbose);
+
+provider.addProvider(traceSubprovider);
+```
+
+After your test suite is complete (e.g in the Mocha global `after` hook), you'll need to call:
+
+```typescript
+await traceSubprovider.writeTraceAsync();
+```
+
+This will create a `trace.json` file in a `trace` directory. This file has an [Istanbul format](https://github.com/gotwarlost/istanbul/blob/master/trace.json.md) - so you can use it with any of the existing Istanbul reporters.

+## 0x-contract-demo
+
+A demonstration of calling 0x smart contracts from Python.
+
+Read the [documentation](http://0x-contract-demo-py.s3-website-us-east-1.amazonaws.com/)
+
+## Contributing
+
+We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Code and Dependencies
+
+Ensure that you have installed Python >=3.6 and Docker. Then:
+
+```bash
+pip install -e .[dev]
+```
+
+### Test
+
+Tests depend on a running ganache instance with the 0x contracts deployed in it. For convenience, a docker container is provided that has ganache-cli and a snapshot containing the necessary contracts. A shortcut is provided to run that docker container: `./setup.py ganache`. With that running, the tests can be run with `./setup.py test`.
+
+### Clean
+
+`./setup.py clean --all`
+
+### Lint
+
+`./setup.py lint`
+
+### Build Documentation
+
+`./setup.py build_sphinx`
+
+### More
+
+See `./setup.py --help-commands` for more info.
