-# Advanced usage
+## Working with lockfiles
+
+All supported package managers recommend that you **always** commit the lockfile, although implementations vary doing so generally provides the following benefits:
+
+- Enables faster installation for CI and production environments, due to being able to skip package resolution.
+- Describes a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.
+- Provides a facility for users to "time-travel" to previous states of `node_modules` without having to commit the directory itself.
+- Facilitates greater visibility of tree changes through readable source control diffs.
+
+In order to get the most out of using your lockfile on continuous integration follow the conventions outlined below for your respective package manager.
+
+### NPM
+
+Ensure that `package-lock.json` is always committed, use `npm ci` instead of `npm install` when installing packages.
+
+**See also:**
+- [Documentation of `package-lock.json`](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json)
+- [Documentation of `npm ci`](https://docs.npmjs.com/cli/v8/commands/npm-ci)
+
+### Yarn
+
+To ensure that `yarn.lock` is always committed, use `yarn install --immutable` when installing packages.
+
+**See also:**
+- [Documentation of `yarn.lock`](https://classic.yarnpkg.com/en/docs/yarn-lock)
+- [Documentation of `--frozen-lockfile` option](https://classic.yarnpkg.com/en/docs/cli/install#toc-yarn-install-frozen-lockfile)
+- [QA - Should lockfiles be committed to the repoistory?](https://yarnpkg.com/getting-started/qa/#should-lockfiles-be-committed-to-the-repository)
+- [Documentation of `yarn install`](https://yarnpkg.com/cli/install)
+
+### PNPM
+
+Ensure that `pnpm-lock.yaml` is always committed, when on CI pass `--frozen-lockfile` to `pnpm install` when installing packages.
+
+**See also:**
+- [Working with Git - Lockfiles](https://pnpm.io/git#lockfiles)
