+Workflow in a Colab notebook
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you're in a Colab notebook (or similar) with no direct access to a terminal, here is the workflow you can use to
+upload your model. You can execute each one of them in a cell by adding a ! at the beginning.
+
+First you need to install `git-lfs` in the environment used by the notebook:
+
+.. code-block:: bash
+
+    sudo apt-get install git-lfs
+
+Then you can use the :obj:`transformers-cli` to create your new repo:
+
+
+.. code-block:: bash
+
+    transformers-cli login
+    transformers-cli repo create your-model-name
+
+Once it's created, you can clone it and configure it (replace username by your username on huggingface.co):
+
+.. code-block:: bash
+
+    git clone https://huggingface.co/username/your-model-name
+    cd your-model-name
+    git lfs install
+    git config --global user.email "email@example.com"
+
+Once you've saved your model inside, you can add it and push it with usual git commands. Note that you have to replace
+`username:password` with your username and password to huggingface.co.
+
+.. code-block:: bash
+
+    git add .
+    git commit -m "Initial commit"
+    git push https://username:password@huggingface.co/username/your-model-name
