+# Edit your repositories INFO.yaml quickly!
+
+Using that tool it's possible to edit as many INFO.yaml files as you wish. It's not needed to execute the same operations for each of the repository you maintain.
+
+Nowadays only the committer deletion action is available, but addition option should be added soon.
+
+## Requirements
+
+### System requirements
+
+Python 3.10 version is needed to run that tool.
+
+### Virtual environment
+
+It's recommended to create a virtual environment to install all dependencies. Create a virtual env using below command
+
+```
+$ python3.10 -m venv .virtualenv
+```
+
+Virtual environment will be created under `.virtualenv` directory.
+To activate virtual environemnt call
+
+```
+$ source .virtualenv/bin/activate
+```
+
+### Python requirements
+
+- [click](https://click.palletsprojects.com/en/8.0.x/)
+- [GitPython](https://gitpython.readthedocs.io/en/stable/index.html)
+- [ruamel.yaml](https://yaml.readthedocs.io/en/latest/)
+
+Install Python requirements calling
+
+```
+$ pip install -r requirements.txt
+```
+
+## Usage

+```
+---
+repos:  # List of the repositories which are going to be udated.
+        # That tool is not smart enough to resolve some conflicts etc.
+        # Please be sure that it would be possible to push the change to the gerrit.
+        # Remember that commit-msg hook should be executed so add that script into .git/hooks dir
+    - path: abs_path_to_the_repo  # Local path to the repository
+      branch: master              # Branch which needs to be udated
+committers:  # List of the committers which are going to be edited
+    - name: Committer Name  # The name of the committer which we would delete or add
+      action: Deletion|Addition  # Addition or deletion action
+    link: https://link.to.the.tcs.confirmation  # Link to the ONAP TSC action confirmation
+commit:  # Configure the commit message
+    message:  # List of the commit message lines. That's optional
