+# Assignment Proposal
+
+## Title
+
+Contributing to Imgbot, friendly robot that optimizes images of your repository
+
+## Names and KTH ID
+
+- Leon Sandner (sandner@kth.se)
+
+## Deadline
+
+Deadline for task 3
+
+## Category
+
+Contribution to open-source
+
+## Description
+Imgbot crawls all your image files in GitHub and submits pull requests after applying a loss less compression. 
+This will make the file size go down, but leave the dimensions and quality just as good. <br>
+I want to dive into the topic of software bots, I never used this project but think it is very useful and I want to contribute to it. <br>
+The repo has an active community and is big enough (883 stars)<br>
+The issue is relevant and current, issue #1068 is also pinned by a community member. <br>
+To resolve this issue, I will add a new feature that will convert the size of the images to the correct respective multi-byte notation.</br>
+As I have not yet used this project before, the effort for me should be enough for me to pass this assignment.
