Cover letter writing strategy

Now I'm going to systematize information about cover letter writing.
Action plan:
- analyse job requirements;
- clarify all key demands;
- find synonyms for each key's demand
- analyse whether  your skills suite to all demands, or at least to major part
- describe your skills using synonyms from step above

para 2. Body. Skill description
Use description of your skills from the last step of action plan.
para 3. Conclusion. -- not finished yet
