 * Model training
-* Model conversion to tflite (and add metadata) <-- tflite model can reside in a team members' GitHub, in your project repo or on TFHub. Please validate the tflite with metadata in the Android app especially if you are publishing it to TFHub for wider adoption.

+*Note that you can also write a blog post about model conversion processes that are generally non-trivial. Here's a good example - [Optimizing MobileDet for Mobile Deployments](https://sayak.dev/mobiledet-optimization/). If you want to benchmark multiple TensorFlow Lite models and write a blog post comparing their performance aspects we welcome that as well. Refer to this blog post - [A Battle of Text Detectors for Mobile Deployments: CRAFT vs. EAST](https://sayak.dev/optimizing-text-detectors/) if you are interested in writing such materials.*
 
-Step 3. If you are interested in helping out, please create a project repo and add the link to the E2E TFLite Tutorials README. Update project to "In Progress" section.  
-Step 4. After project is completed, move from "In progress " to "Completed" section on E2E TFLite Tutorials. And request with a PR to add your project to [awesome-tflite].
