+# Buidler to Hardhat plugin migration guide
+
+This is a short guide explaining how to turn a Buidler plugin into a Hardhat one.
+
+## Updating its dependencies
+
+### Core package
+
+References to the `@nomiclabs/buidler` package should be replaced with the `hardhat` package in your `package.json`, and your `import`s or `require`s.
+
+For example, you would import the `extendEnvironment` function this way:
+
+```typescript
+import { extendEnvironment } from "hardhat/config";
+```
+
+### Plugins
+
+Similarly, references to buidler plugins should be replaced with their corresponding hardhat plugins.
+For example, `@nomiclabs/buidler-ethers` would be `@nomiclabs/hardhat-ethers`.
+
+## Adapting your plugin's source code
+
+The first change you need to make, is to stop exporting a function in your plugin's `index.ts`. Place your function's body at the top-level of your `index.ts` file.
+
+Then, replace all types or imported names that include `Buidler` with `Hardhat` in your plugin source code.
+
+For example, the `BuidlerRuntimeEnvironment` should be replaced with the `HardhatRuntimeEnvironment`. We suggest using `hre` instead of `bre` as its variable name.
+
+### Artifacts
+
+The `readArtifact` and `readArtifactSync` functions were moved to the `HardhatRuntimeEnvironment` so you must replace their uses like this:
+
+```js
+const tokenArtifact = await hre.artifacts.readArtifact("Token");
+```
+
+The artifact format is now supplemented with build information and debug artifacts in Hardhat which allows you to read things like contract symbols. See the [documentation](https://hardhat.org/docs/artifacts) for more information.
+
+## Updating your plugin's tests
+
+Apart from updating types and names, fixture projects need their `buidler.config.js` renamed to `hardhat.config.js`.
+
+### Changes needed to your test projects' config
+
+The compiler configuration is now expected in the `solidity` field instead of `solc`. Note that Hardhat projects allow multiple solidity versions in its compilation pipeline. For more information see its [documentation](https://hardhat.org/docs/compilation).
+
+Besides that, the compiler settings now go inside a `settings` field. For example, a configuration like this:
+
+```
+module.exports = {
+    solc: {
+        version: "0.7.2"
+        optimizer: {
+            enabled: true,
+            runs: 200
+        }
+    }
+}
+```
+
+needs to be replaced with this:
+
+```js
+module.exports = {
+    solidity: {
+        version: "0.7.2"
+        settings: {
+            optimizer: {
+                enabled: true,
+                runs: 200
+            }
+        }
+    }
+}
+```
+
+## Adapting your type extensions
+
+Hardhat introduced a few changes in how type extensions are created and used.
+
+These are the necessary changes to update your plugin.
+
+First, you need rename your `src/type-extenstions.d.ts` file to `src/type-extensions.ts`.
+
+Then, you need to add an `import "./type-extensions";` in your `src/index.ts` file, or the main entrypoint to your plugin as defined in your `package.json`.
+
+### Extending Hardhat types
+
+Hardhat types are meant to be imported from `hardhat/types`, but when extending them,
+you should import them from the module that declares them.
+
+For example, if you want you use the `HardhatRuntimeEnvironment` type, you should import it with:
+
+```typescript
+import { HardhatRuntimeEnvironment } from "hardhat/types";
+```
+
+But if you want to extend it, you should import the module that declares it
+instead, which is `hardhat/types/runtime`.
+
+```typescript
+import "hardhat/types/runtime";
+
+declare module "hardhat/types/runtime" {
+  export interface HardhatRuntimeEnvironment {
+    newField: number;
+  }
+}
+```
+
+### Adapting your config extensions
+
+Config types are handled slightly differently in Hardhat.
+
+For each config element/type, there's two Typescript types defined. One
+that ends with `UserConfig`, that represents the user's input, and another
+one that ends with just `Config`, which represents the configuration values
+after any resolution and default values have been applied. The first kind of
+types is used by users when writing their config. The second one is used
+during the execution of tasks, tests and scripts, and is present in the
+Hardhat Runtime Environment.
+
+For example, `HardhatUserConfig` represents the entire config written by the
+user, and all of its fields are optional. `HardhatConfig`, is the result
+of resolving/normalizing it, and applying default values. None of its fields
+are optional.
+
+Some types have been renamed to match this new pattern:
+
+- `ProjectPaths` is now `ProjectPathsUserConfig`
+- `Networks` is now `NetworksUserConfig`
+- Both have their resolved versions: `ProjectPathsConfig` and
+  `NetworksConfig`, respectively.
+
+You can find an example of how to properly extend these types,
+resolve/normalize the users's config, and apply default values in the
+`src/type-extensions.ts` and `src/index.ts` files.
+
+### How type extensions are loaded in Hardhat
+
+Previously, type extensions were loaded by plugin users by adding references to a plugin-owned `type-extensions.d.ts` in their `tsconfig.json`.
+
+Now, they're loaded automatically when importing the plugin in a hardhat config file. For example:
+
+```typescript
+import "@nomiclabs/hardhat-ethers"
+```
+
+This is enough to import the type extensions included in the `@nomiclabs/hardhat-ethers` plugin.
+
+## Adapting your `README.md`
+
+Make sure to update the README to point to the new Hardhat site (https://hardhat.org), and that the Typescript Support section has been updated.

+# Hardhat TypeScript plugin boilerplate
+
+This is a sample Hardhat plugin written in TypeScript. Creating a Hardhat plugin
+can be as easy as extracting a part of your config into a different file and
+publishing it to npm.
+
+This sample project contains an example on how to do that, but also comes with
+many more features:
+
+- A mocha test suite ready to use
+- TravisCI already setup
+- A package.json with scripts and publishing info
+- Examples on how to do different things
+
+## Installation
+
+To start working on your project, just run
+
+```bash
+npm install
+```
+
+## Plugin development
+
+Make sure to read our [Plugin Development Guide](https://hardhat.org/advanced/building-plugins.html) to learn how to build a plugin.
+
+## Testing
+
+Running `npm run test` will run every test located in the `test/` folder. They
+use [mocha](https://mochajs.org) and [chai](https://www.chaijs.com/),
+but you can customize them.
+
+We recommend creating unit tests for your own modules, and integration tests for
+the interaction of the plugin with Hardhat and its dependencies.
+
+## Linting and autoformat
+
+All of Hardhat projects use [prettier](https://prettier.io/) and
+[tslint](https://palantir.github.io/tslint/).
+
+You can check if your code style is correct by running `npm run lint`, and fix
+it with `npm run lint:fix`.
+
+## Building the project
+
+Just run `npm run build` ️👷
+
+## README file
+
+This README describes this boilerplate project, but won't be very useful to your
+plugin users.
+
+Take a look at `README-TEMPLATE.md` for an example of what a Hardhat plugin's
+README should look like.
+
+## Migrating from Buidler?
+
+Take a look at [the migration guide](MIGRATION.md)!
