+## Technical File
+
+### Objective
+
+To prepare to compile a technical file, with a view to obtaining the Level 7 RNCP title of Cloud DevOps expert.
+
+You'll write a project report for each project you validate during your training, so that you can trace your achievements. You'll use your reports to compile a **personal** technical file at the end of your study period.
+
+### Preparing for your technical file
+
+Each time you validate a project (whether alone or in a group), you'll need to write a report. This must be completed individually, so that is shows **your** understanding.
+
+The focus of your technical file is to detail what you have learned, and what you have achieved during your training. This allows you to demonstrate your mastery of:
+
+- Knowledge of Cloud Service Providers and Infrastructure
+- Automation and orchestration of containerized services
+- DevOps project management
+
+You should write and store your reports inside the repository of this project. The repository will be comprised of a series of markdown files, with one for each project that you validate during your training. These should be named as `project-name.md`, so that you can trace your progress.
+
+You will have 5 additional days beyond the end of your training to finalize your technical file.
+
+### Contents of the reports
+
+The reports must detail a description of the project, and justifications for your choices. You should cover:
+
+- The problem you needed to solve
+- The constraints you needed to work with
+- The different stages of solving the problem:
+  - Continuous integration
+  - Continuous delivery
+  - Quality control
+- The technological choices you made
+- The expected results, and anticipated problems
+- The obtained results, and actual problems faced
+
+### Compiling the technical file
+
+You will have 5 days after the end of your training period in which to finalize your technical file.
+
+Your technical files must be an individual piece of work, and be comprised of approximately 8-10 pages.
+
+You will rely on the contents of your project reports in order to trace your achievements.
+
+Particular care must be given to spelling and presentation.
