+
+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.
