+
+## developing the ZIM UI in Vue.JS
+
+Sometimes you need to alter something in the ZIM UI in Vue.JS but for this to work, you need assets which are generated by the scraper (e.g. channel.json, ...).
+
+To simplify this, it is possible to:
+- run the scraper (with original code base or your modified one)
+- extract assets from generated files and place them in a directory where ZIM UI will find them
+- iterate on ZIM UI code
+
+To achieve this, first build the Docker image based on current code base.
+
+```
+docker build -t local-youtube2zim .
+```
+
+Scrape a channel (here we use the [openZIM_testing](https://www.youtube.com/channel/UC8elThf5TGMpQfQc_VE917Q) channel, but you could use any other one of interest for your UI developments).
+
+```
+docker run --rm -it -v "$PWD/output":/output local-youtube2zim youtube2zim --api-key <YOUR-API-KEY> --type channel --id "UC8elThf5TGMpQfQc_VE917Q" --name "openZIM_testing" --zim-file "openZIM_testing"
+```
+
+Extract interesting ZIM content and move it to `public` folder.
+
+```
+find zimui/public/ -mindepth 1 ! -name ".gitignore" -delete
+docker run -it --rm -v $(pwd)/output:/data ghcr.io/openzim/zim-tools:latest zimdump dump --dir=/data/openZIM_testing /data/openZIM_testing.zim
+sudo chown -R $(id -u -n):$(id -g -n) output/openZIM_testing
+mv output/openZIM_testing/* zimui/public/
+rm -rf output/openZIM_testing
+```
+
+Start ZIM UI locally.
+
+```
+cd zimui
+yarn dev
+```
+
+Do not forget to cleanup `public` folder before building the docker image again, otherwise all assets will be pushed to the ZIM.
+
+## testing with cypress
+
+Cypress is used for end-to-end testing of the ZIM UI. It allows you to write tests that simulate user interactions with the application to ensure everything works as expected.
+
+To run the tests, you need to start the ZIM UI locally and then run the tests.
+
+```
+cd zimui
+yarn dev
+yarn test:e2e
+```
+
+On Linux, you might need to install additional dependencies, see [Linux Prerequisites](https://docs.cypress.io/guides/getting-started/installing-cypress#Linux-Prerequisites) in the Cypress documentation.
