+### Installation
+
+```bash
+corepack enable
+pnpm install
+```
+
+This installs all the dependencies for all the packages and builds the `@netlify/remix-runtime`,
+`@netlify/remix-adapter`, `@netlify/remix-edge-adapter`, and `@netlify/vite-plugin-react-router` packages.
+
+### Testing
+
+To build the packages, run the build command.
+
+```bash
+pnpm run build:packages
+```
+
+Run the build watch command to have packages built when they are changed.
+
+```bash
+pnpm run build:packages:watch
+```
+
+To run unit tests:
+
+```bash
+pnpm run test:unit
+```
+
+To run all tests (including linting and typechecking):
+
+```bash
+pnpm run test
+```
+
+#### End-to-end integration tests
+
+These tests are meant to be very terse, basic, happy-path "user journey" system tests. These should generally map to
+user-facing features and should rarely be added to.
+
+Prerequisites:
+
+- [Netlify CLI](https://docs.netlify.com/cli/get-started/) installed globally
+- Install Playwright browsers (it should prompt you automatically the first time):
+  - `pnpm exec playwright install --with-deps`
+
+To run end-to-end integration tests:
+
+```bash
+pnpm run test:e2e
+```
+
+To add a new fixture site called `my-fixture`:
+
+1. create a new directory `tests/e2e/fixtures/my-fixture`
+2. register it in `tests/e2e/support/fixtures` as `myFixture`
+3. [inject `myFixture` directly into any test](https://playwright.dev/docs/test-fixtures#using-a-fixture)
