Conclusions
Download
An archive (or more if necessary) with the files obtained from the project: sources, schemes, etc. A README file, a ChangeLog, a compile script and automatic copy on uC always make a good impression 
.
.
Files are uploaded to the wiki using the Add Images or other files feature. The namespace in which the files are uploaded is of the type : pm: prj20 ??: c? or : pm: prj20 ??: c?: Student_name (if applicable). Example: Dumitru Alin, 331CC → : pm: prj2009: cc: dumitru_alin .
