+## Guides
+
+This is a collection of guides on how to run and update `undici`, and how to run different parts of the project.
+
+<a id="update-llhttp"></a>
+### Update `llhttp`
+
+The HTTP parser used by `undici` is a WebAssembly build of [`llhttp`](https://github.com/nodejs/llhttp).
+
+While the project itself provides a way to compile targeting WebAssembly, at the moment we embed the sources
+directly and compile the module in `undici`.
+
+The `deps/llhttp/include` folder contains the C header files, while the `deps/llhttp/src` folder contains
+the C source files needed to compile the module.
+
+The `lib/llhttp` folder contains the `.js` transpiled assets required to implement a parser.
+
+The following are the steps required to perform an update.
+
+#### Clone the [llhttp](https://github.com/nodejs/llhttp) project
+
+```bash
+git clone git@github.com:nodejs/llhttp.git
+
+cd llhttp
+```
+
+#### Checkout a `llhttp` release
+
+```bash
+git checkout <tag>
+```
+
+#### Install the `llhttp` dependencies
+
+```bash
+npm i
+```
+
+#### Run the wasm build script
+
+> This requires [docker](https://www.docker.com/) installed on your machine.
+
+```bash
+npm run build-wasm
+```
+
+#### Copy the sources to `undici`
+
+```bash
+cp build/wasm/*.js <your-path-to-undici>/lib/llhttp/
+
+cp build/wasm/*.js.map <your-path-to-undici>/lib/llhttp/
+
+cp build/wasm/*.d.ts <your-path-to-undici>/lib/llhttp/
+
+cp src/native/api.c src/native/http.c build/c/llhttp.c <your-path-to-undici>/deps/llhttp/src/
+
+cp src/native/api.h build/llhttp.h <your-path-to-undici>/deps/llhttp/include/
+```
+
+#### Build the WebAssembly module in `undici`
+
+> This requires [docker](https://www.docker.com/) installed on your machine.
+
+```bash
+cd <your-path-to-undici>
+
+npm run build:wasm
+```
+
+#### Commit the contents of lib/llhttp
+
+Create a commit which includes all of the updated files in lib/llhttp.
+
+<a id="update-wpts"></a>
+### Update `WPTs`
+
+`undici` runs a subset of the [`web-platform-tests`](https://github.com/web-platform-tests/wpt).
+
+### Requirements:
+- [Node core utils](https://github.com/nodejs/node-core-utils) setup with credentials.
+
+To update every test, run the following commands. Typically you would only need to update the tests in a specific directory.
+
+```bash
+git node wpt resources
+git node wpt interfaces
+git node wpt common
+git node wpt fetch
+git node wpt FileAPI
+git node wpt xhr
+git node wpt websockets
+git node wpt mimesniff
+git node wpt storage
+git node wpt service-workers
+git node wpt eventsource
+```
+
+#### Run the tests
+
+Run the tests to ensure that any new failures are marked as such.
+
+You can mark tests as failing in their corresponding [status](./test/wpt/status) file.
+
+```bash
+npm run test:wpt
+```
+
+<a id="lint"></a>
+### Lint
+
+```bash
+npm run lint
+```
+
+<a id="test"></a>
+### Test
+
+```bash
+npm run test
+```
+
+<a id="coverage"></a>
+### Coverage
+
+```bash
+npm run coverage
+```
+
+<a id="releases"></a>
+### Issuing Releases
+
+Release is automatic on commit to main which bumps the package.json version field.
+Use the "Create release PR" github action to generate a release PR.
+
+<a id="external-builds"></a>
+### Building for externally shared node builtins
+
+If you are packaging `undici` for a distro, this might help if you would like to use
+an unbundled version instead of bundling one in `libnode.so`.
+
+To enable this, pass `EXTERNAL_PATH=/path/to/global/node_modules/undici` to `build/wasm.js`.
+Pass this path with `loader.js` appended to `--shared-builtin-undici/undici-path` in Node.js's `configure.py`.
+If building on a non-Alpine Linux distribution, you may need to also set the `WASM_CC`, `WASM_CFLAGS`, `WASM_LDFLAGS` and `WASM_LDLIBS` environment variables before running `build/wasm.js`.
+
+<a id="benchmarks"></a>
+### Benchmarks
+
+```bash
+cd benchmarks && npm i && npm run bench
+```
+
+The benchmarks will be available at `http://localhost:3042`.
+
+<a id="documentation"></a>
+### Documentation
+
+```bash
+cd docs && npm i && npm run serve
+```
+
+The documentation will be available at `http://localhost:3000`.
