 ```
 $ npm install --save-dev solidity-coverage
 ```
-
-### Run
-Set a `coverage` network in truffle-config.js (see [Network Configuration](#network-configuration)) and then run:
-```
-$ npx solidity-coverage
-```
-
 ### Usage notes:
-+ For pragma solidity >=0.4.22 <0.6.0 / Petersburg / Truffle v4 and v5
-+ Tests run more slowly while coverage is being generated.
-+ Your contracts will be double-compiled and a (long) delay between compilation and
-the beginning of test execution is possible if your contracts are large.
-+ Truffle should be globallly installed in your environment.. If you prefer running truffle as
-a local dependency, please see [this section](https://github.com/sc-forks/solidity-coverage/blob/master/docs/faq.md#running-truffle-as-a-local-dependency) of the FAQ.
-+ If your suite uses native Solidity testing or accesses contracts via mocks stored in `tests/` (a la Zeppelin), coverage will trigger test errors because it can't control the way truffle compiles that folder. Mocks should be relocated to the root `contracts` directory. More on why this is necessary at issue [146](https://github.com/sc-forks/solidity-coverage/issues/146)
-
-### Network Configuration
-
-By default, this tool connects to a coverage-enabled fork of ganache-cli
-called **testrpc-sc** on port 8555.
-+ it's a dependency - there's nothing extra to download.
-+ the solidity-coverage command launches it automatically in the background. (See [this section of the FAQ](https://github.com/sc-forks/solidity-coverage/blob/master/docs/faq.md#running-testrpc-sc-on-its-own) if you need to launch it separately yourself)
++ For pragma solidity >=0.4.22 <0.6.0 / Petersburg
++ Coverage runs tests a little more slowly.
++ Coverage distorts gas consumption. 
++ Coverage launches its own in-process ganache instance. You can
+  set [ganache options](https://github.com/trufflesuite/ganache-core#options) via
+  the `providerOptions` key in your `.solcover.js` config file.
 
-In `truffle-config.js`, add a coverage network following the example below.
+### Truffle V5
 
-**Example**
+Add "solidity-coverage" to your plugins array in `truffle-config.js`
 ```javascript
 module.exports = {
-  networks: {
-    development: {
-      host: "localhost",
-      port: 8545,
-      network_id: "*"
-    },
-    coverage: {
-      host: "localhost",
-      network_id: "*",
-      port: 8555,         // <-- If you change this, also set the port option in .solcover.js.
-      gas: 0xfffffffffff, // <-- Use this high gas value
-      gasPrice: 0x01      // <-- Use this low gas price
-    },
-    ...etc...
-  }
-};
+  networks: {...},
+  plugins: ["solidity-coverage"]
+}
+```
+Run
+```
+truffle run coverage [options]
 ```
-### Options
+
+
+### Command Options
+| Option       | Example                        | Description |
+|--------------|--------------------------------|-------------|
+| --file       | --file="test/registry/*.js"    | Filename or glob describing a subset of JS tests to run. (Globs must be enclosed by quotes.)|
+| --solcoverjs | --solcoverjs ./../.solcover.js | Relative path from working directory to config. Useful for monorepo packages that share settings. (Path must be "./" prefixed) |
+| --version    |                                | Version info |
+| --help       |                                | Usage notes  |
+|<img width=250/>|<img width=500/>              |<img width=100/>|
+
+### Config Options
 
 Additional options can be specified in a `.solcover.js` config file located in
 the root directory of your project.
 
 **Example:**
 ```javascript
 module.exports = {
-    port: 6545,
-    testrpcOptions: '-p 6545 -u 0x54fd80d6ae7584d8e9a19fe1df43f04e5282cc43',
-    testCommand: 'mocha --timeout 5000',
-    norpc: true,
-    dir: './secretDirectory',
-    copyPackages: ['openzeppelin-solidity'],
-    skipFiles: ['Routers/EtherRouter.sol']
+  skipFiles: ['Routers/EtherRouter.sol']
 };
 ```
 
 
 | Option | Type | Default | Description |
 | ------ | ---- | ------- | ----------- |
-| accounts | *Number* | 35 | Number of accounts to launch testrpc with. |
-| port   | *Number* | 8555 | Port to run testrpc on / have truffle connect to |
-| norpc | *Boolean* | false | Prevent solidity-coverage from launching its own testrpc. Useful if you are managing a complex test suite with a [shell script](https://github.com/OpenZeppelin/openzeppelin-solidity/blob/ed872ca0a11c4926f8bb91dd103bea1378a3384c/scripts/coverage.sh) |
-| testCommand | *String* | `truffle test` |  Run an arbitrary test command. ex: `mocha --timeout 5000`. NB: Also set the `port` option to whatever your tests require (probably 8545). |
-| testrpcOptions | *String* | `--port 8555` | options to append to a command line invocation of testrpc. NB: Using this overwrites the defaults so always specify a port in this string *and* in the `port` option |
-| copyNodeModules | *Boolean* | false | :warning:  **DEPRECATED** use `copyPackages` instead :warning: Copies `node_modules` into the coverage environment. May significantly increase the time for coverage to complete if enabled. Useful if your contracts import solidity files from an npm installed package (and your node_modules is small). |
-| copyPackages | *Array* | `[]` | Copies specific `node_modules` packages into the coverage environment. May significantly reduce the time for coverage to complete compared to `copyNodeModules`. Useful if your contracts import solidity files from an npm installed package. |
+| client | *Object* | require("truffle").ganache | Useful if you need a specific ganache version. (usage: `client: require("ganache-core")`)|
+| providerOptions | *Object* | {} | ganache-core options (ex: `network_id: 55`). Complete list of options [here](https://github.com/trufflesuite/ganache-core#options).  |
 | skipFiles | *Array* | `['Migrations.sol']` | Array of contracts or folders (with paths expressed relative to the `contracts` directory) that should be skipped when doing instrumentation. `Migrations.sol` is skipped by default, and does not need to be added to this configuration option if it is used. |
-| deepSkip | boolean | false | Use this if instrumentation hangs on large, skipped files (like Oraclize). It's faster. |
-| dir | *String* | `.` | Solidity-coverage copies all the assets in your root directory (except `node_modules`) to a special folder where it instruments the contracts and executes the tests. `dir` allows you to define a relative path from the root directory to those assets. Useful if your contracts & tests are within their own folder as part of a larger project.|
-| buildDirPath | *String* | `/build/contracts` | Build directory path for compiled smart contracts |
 | istanbulReporter | *Array* | ['html', 'lcov', 'text'] | Coverage reporters for Istanbul. Optional reporter replaces the default reporters. |
