+# Evaluating menuQA flow
+
+## Build it
+
+```
+pnpm build
+```
+
+or if you need to, build everything:
+
+```
+cd ../../../; pnpm build; pnpm pack:all; cd -
+```
+
+## Run setup
+
+This will add the `GenkitGrubPub.pdf` to your index
+
+```
+genkit flow:run setup
+```
+
+or add more pdfs to the index if you want:
+
+```
+genkit flow:run setup '["./path/to/your/file.pdf"]'
+```
+
+## Run the flow via cli
+
+```
+genkit flow:run menuQA '"What burgers are on the menu?"'
+```
+
+## Run the flow in the Developer UI
+
+```
+genkit start
+```
+
+Click on the menuQA flow in the lefthand navigation panel to playground the new flow.
