+## ESLint
+
+To improve the quality of our JS and VueJS code, ESLint and eslint-plugin-vue are implemented within the chill-bundles project.
+
+### Commands
+
+To run ESLint, you can simply use the [`eslint`` command within the chill-bundles directory.
+This runs eslint **not** taking the baseline into account, thus showing all existing errors in the project.
+
+A script was also added to package.json allowing you to execute ``yarn run eslint``.
+This will run eslint, but **taking the baseline into account**, thus only alerting to newly created errors.
+
+The eslint command is configured to also run ``prettier`` which will simply format the code to look more uniform (takes care indentation for example).
+
+Interesting options that can be used in combination with eslint are:
+
+- ``--quiet`` to only get errors and silence the warnings
+- ``--fix`` to have ESLint fix what it can, automatically. This will not fix everything.
+
+### Baseline
+
+To allow us the time to fix linting errors/warnings, a baseline has been created using the following command
+- ``npx eslint-baseline "**/*.{js,vue}"``
+
+The baseline has been committed and the gitlab CI setup to only fail upon new errors/warnings being created.
+When fixing errors/warnings manually, please update the baseline.
+
+1. Delete the current baseline file
+2. Run the above command locally, this will automatically create a new baseline that should be commited
+
+### Rules
+
+We use Vue 3, so the rules can be configured as follows within the ``eslint.config.mjs`` file:
+
+- ``.configs["flat/base"]`` ... Settings and rules to enable correct ESLint parsing.
+
+Configurations for using Vue.js 3.x:
+
+- ``.configs["flat/essential"]`` : Base rules plus rules to prevent errors or unintended behavior.
+- ``.configs["flat/strongly-recommended"]`` ... Above, plus rules to considerably improve code readability and/or dev experience.
+- ``.configs["flat/recommended"]`` ... Above, plus rules to enforce subjective community defaults to ensure consistency.
+
+Detailed information about which rules each set includes can be found here:
+`https://eslint.vuejs.org/rules/ ](https://eslint.vuejs.org/rules/)
+
+### Manual Rule Configuration
+
+We can also manually configure certain rules or override rules that are part of the ruleset specified above.
+
+For example, if we want to turn off a certain rule, we can do so as follows:
+
+    rules: {
+      'vue/multi-word-component': 'off'
+    }
+
+We could also change the severity of a certain rule from 'error' to 'warning', for example.
+
+Within specific ``.js`` or ``.vue`` files, we can also override a certain rule only for that specific file by adding a comment:
+
+    /* eslint multi-word-component: "off", no-child-content: "error"
+    --------
+    Here's a description about why this configuration is necessary. */
