+# How to upgrade definition version?
+
+If you want to upgrade the current definition to a new version, use the following [CHANGELOG](CHANGELOG.md).
+
+## How to proceed:  
+
+1. Take your current definition, and in `config.yml`, check the version.  
+
+2. Change the version in `config.yml` to a new version.
+
+3. Use the [CHANGELOG](CHANGELOG.md) and start making changes step by step from your current version to the newest version that is compatible with IXP.  
+
+4. Make one single change at a time.  
+
+5. Be sure to make the change for all the concerning files and their attributes before proceeding with the following change. 
+
+6. Each version contains information about changes and a structured description of affected files and their arguments. 
+
+7. Note that not every change is reflected in the files, some changes are only concerned with the behaviour of certain definition aspect rather than syntax change in the YAML files. 
+
+8. Lastly, check the new version against [definition documentation](README.md) to see if the arguments in the files are the same. 
+
+9. Zip the definition and upload it to the IXP for the last validation.  
+
+10. **Done.** Enjoy your upgraded version!
+
+## Example:
+
+* Current version: **0.8.0**
+* New version: **0.9.0**
+
+1. In the [CHANGELOG](CHANGELOG.md) in the section **0.9.0** the only change is removal of field `auto` in `injects.yml`. 
+2. Open `injects.yml`. Remove field `auto` from every inject category. 
+3. Save the file.
+4. Check the `injects.yml` against `injects.yml` structure in the [definition documentation](README.md).
+5. Create a new .zip archive and upload it to the IXP. 
+6. The upload process will check the definition for errors.
+
+**You have successfully upgraded the definition version.**
