+# Contribution guidelines
+
+First of all, thanks for thinking of contributing to this project. :smile:
+
+Before sending a Pull Request, please make sure that you're assigned the task on a GitHub issue.
+
+- If a relevant issue already exists, discuss on the issue and get it assigned to yourself on GitHub.
+- If no relevant issue exists, open a new issue and get it assigned to yourself on GitHub.
+
+Please proceed with a Pull Request only after you're assigned. It'd be sad if your Pull Request (and your hardwork) isn't accepted just because it isn't idealogically compatible.
+
+# Developing the gem
+
+1. Install with
+
+  ```sh
+  git clone 
+  cd colorls
+  gem install bundler
+  bundle install
+  ```
+
+2. Make your changes in a different git branch. These changes can be
+
+  - add better icons to [YAML files](lib/yaml/)
+  - add more flag options to the ruby gem.
+
+
+3. (Optional) To test whether `lc` is working properly, do 
+  ```sh
+  rake install
+  lc # start using lc
+  ```
+
+4. (Required for YAML file changes) These are the specifications for the YAML files -
+
+  - `files.yaml`, `folders.yaml` : The keys are sorted alphabetically.
+  - `file_aliases.yaml`, `folder_aliases.yaml` : The values are sorted alphabetically. For each set of keys mapping to a value, those set of keys are also sorted alphabetically.
+
+5. Check before pushing
+
+  ```sh
+  bundle exec rubocop
+  bundle exec rspec
+  ```
