 # ulmfit-multilingual
 Temporary repository used for collaboration on application of for multiple languages.
+
+## how to contribute
+We have a fork of fastai to propose changes to fastai.text, with a branch for this project:
+ https://github.com/n-waves/fastai/tree/ulmfit_multilingual  
+
+Let us know that you want to start collaboration on fastai forum thread: [Multilingual ULMFIT](https://forums.fast.ai/t/multilingual-ulmfit/28117)
+and you will get access to both repositories.
+
+Follow the developer [installation of fastai] (https://github.com/fastai/fastai#developer-install)
+Add n-waves/fastai as additional remote as described here: https://help.github.com/articles/adding-a-remote/
+Here is what I've did:
+```bash
+
+$ git remote add n-waves https://github.com/n-waves/fastai.git
+$ git remote -v 
+n-waves	https://github.com/n-waves/fastai.git (fetch)
+n-waves	https://github.com/n-waves/fastai.git (push)
+origin	https://github.com/fastai/fastai.git (fetch)
+origin	https://github.com/fastai/fastai.git (push)
+
+$ git fetch n-waves
+$ git checkout ulmfit_multilingual
+Branch 'ulmfit_multilingual' set up to track remote branch 'ulmfit_multilingual' from 'n-waves'.
+Switched to a new branch 'ulmfit_multilingual'
+
+$ git push --set-upstream m-waves ulmfit_multilingual  # to automatically push ulmfit_multilingual branch to the n-waves repo
+```
