+# `@now/next` Legacy Mode
+
+#### Why This Warning Occurred
+
+`@now/next` has two modes: `legacy` and `serverless`. You will always want to use the `serverless` mode. `legacy` is to provide backwards compatibility with previous `@now/next` versions.
+
+The differences:
+
+Legacy:
+
+- Minimal lambda size of `2.2Mb` (approximately)
+- Forces `next@v7.0.2-canary.49` and `next-server@v7.0.2-canary.49`
+- Forces all `dependencies` to be `devDependencies`
+- Loads `next.config.js` on bootup, breaking sometimes when users didn't use `phases` to load files
+- Used `next-server` which is the full Next.js server with routing etc.
+- Runs `npm install`
+- Runs `npm run now-build`
+- Runs `npm install --production` after build
+
+Serverless:
+
+- Minimal lambda size of `49Kb` (approximately)
+- Uses Next.js build targets (`target: 'serverless'`) in `next.config.js`. [documentation](https://github.com/zeit/next.js#summary)
+- Does not make changes to your application dependencies
+- Does not load `next.config.js` ([as per the serverless target documentation](https://github.com/zeit/next.js#summary))
+- Runs `npm install`
+- Runs `npm run now-build`
+- Does not run `npm install --production` as the output from the build is all that's needed to bundle lambdas.
+- No runtime dependencies, meaning smaller lambda functions
+- Optimized for fast [cold start](https://zeit.co/blog/serverless-ssr#cold-start)
+
+
+#### Possible Ways to Fix It
+
+In order to create the smallest possible lambdas Next.js has to be configured to build for the `serverless` target.
+
+1. Serverless Next.js requires Next.js 8 or later, to upgrade you can install the `latest` version: 
+
+```
+npm install next --save
+```
+
+2. Add the `now-build` script to your `package.json`
+
+```json
+{
+  "scripts": {
+    "now-build": "next build"
+  },
+}
+```
+
+3. Add `target: 'serverless'` to `next.config.js`
+
+```js
+module.exports = {
+  target: 'serverless'
+  // Other options are still valid
+}
+```
+
+4. Optionally make sure the `"src"` in `"builds"` points to your application `package.json`
+
+```js
+{
+  "version": 2,
+  "builds": [{ "src": "package.json", "use": "@now/next" }]
+}
+```

+# `@now/next` No Serverless Pages Built
+
+#### Why This Error Occurred
+
+This error occurs when you have your application is not configured for Serverless Next.js build output.
+

+
+```js
+module.exports = {
+  target: 'serverless'

+
+4. Remove `distDir` from `next.config.js` as `@now/next` can't parse this file and expects your build output at `/.next`
+
+5. Optionally make sure the `"src"` in `"builds"` points to your application `package.json`
+
+```js
+{
+  "version": 2,
+  "builds": [{ "src": "package.json", "use": "@now/next" }]
