-### Hardhat
-
-Beginning with v0.7.12, this tool supports Hardhat and runs directly on
-HardhatEVM.
-
 **Require** the plugin in `hardhat.config.js` ([Hardhat docs][26])
 ```javascript
 require('solidity-coverage')
 ```
 
-**Run**
+Or, if you are using TypeScript, add this to your hardhat.config.ts:
+```ts
+import 'solidity-coverage'
 ```
-npx hardhat coverage [command-options]

-### @openzeppelin/test-environment
 
-OpenZeppelin have written their own coverage generation scripts for `test-environment` using the solidity-coverage API.
-A working example can be found at [openzeppelin-contracts, here.][35]
 
-## Usage notes:
-+ Coverage runs tests a little more slowly.
-+ Coverage launches its own in-process ganache server.
-+ You can set [ganache options][1] using the `providerOptions` key in your `.solcover.js` [config][15].
-+ Coverage [distorts gas consumption][13]. Tests that check exact gas consumption should be [skipped][24].
-+ :warning:  Contracts are compiled **without optimization**. Please report unexpected compilation faults to [issue 417][25]
+## Run
+```
+npx hardhat coverage [command-options]
