+### Description
+These utility scripts avoid copying each ci variable manually which is tedious.
+- The gitlab-ci-vars-reader.py reads variables from a specific project or a pipeline (depending on the options provided) and copies them into a yaml file
+- The gitlab-ci-vars-updater.py takes a yaml file containing key value pairs in yaml format as an input. It then creates/updates project variables or pipeline variables (depending on the options provided)
+
+### Prerequisites
+```
+python -m venv ~/venvs/gitlab
+source ~/venvs/gitlab/bin/activate
+pip install -r requirements
+```
+
+### Setup
+```
+cd utils
+mv gitlab.ini.example gitlab.ini
+```
+Make changes to the gitlab.ini as you require.
+[Create a personal access token](https://docs.gitlab.com/user/profile/personal_access_tokens/) via the gitlab UI and copy it to the private_token field in gitlab.ini file
+
+### Usage
+> Create an empty schedule pipeline before you try this out.
+```
+python3 gitlab-ci-vars-reader.py --config_file gitlab.ini --project_id <PROJECT_ID> --sched_pipeline_id <PIPELINE_ID> --var_file ci-variables.yaml
+
+python3 gitlab-ci-vars-updater.py --config_file gitlab.ini --project_id <PROJECT_ID> --sched_pipeline_id <NEW-PIPELINE_ID> --var_file ci-variables.yaml
