 The CoverageSubprovider 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.
 
+Coverage 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 `CoverageSubprovider` with your favorite framework you need to pass an `artifactsAdapter` to it.
+
+### Sol-compiler
+
+If you are generating your artifacts with [@0xproject/sol-compiler](LINK) you can use the `SolCompilerArtifactsAdapter` we've implemented for you.
+
+```typescript
+<<<<<<< HEAD
+import { CoverageSubprovider } from '@0xproject/sol-cov';
+=======
+import { SolCompilerArtifactsAdapter } from '@0xproject/sol-cov';
+const artifactsPath = 'src/artifacts';
+const contractsPath = 'src/contracts';
+const artifactsAdapter = new SolCompilerArtifactsAdapter(artifactsPath, contractsPath);
+```
+
+### Truffle
+
+If your project is using [Truffle](LINK), we've written a `TruffleArtifactsAdapter`for you.
+
+```typescript
+import { TruffleArtifactAdapter } from '@0xproject/sol-cov';
+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 { CoverageSubprovider } from '@0xproject/sol-cov';
+import ProviderEngine = require('web3-provider-engine');

 const provider = new ProviderEngine();
