+# Implementing in monorepo
+
+When installing Docz in a monorepo environment you might need some extra steps to get everything working correctly.
+
+Let's say we have a lerna monorepo with workspaces defines as: `packages/**/*`, in a folder structure it would look like this:
+
+```
+packages
+|_ components
+|_ portal
+|___ package.json
+```
+
+Docz and @foo/component would be a dependency in `portal/package.json`. As Docz copies over this package.json to `portal/.docz/package.json`
+you might run into `error There are more than one workspace with name "@foo/portal"`. In order to fix this add
+a couple lines to your `portal/package.json`:
+
+```
+//portal.package.json
+{
+  "private": true,
+  "workspaces": [
+    // needed to resolve @foo/components in portal/package.json
+    "../../packages/**/*",
+    // needed to resolve @foo/components in portal/.docz/package.json
+    "../../../packages/**/*"
+  ]
+}
+```
+
+You might need to tweak these paths to match your monorepo structure
