 After logging into Gitpod or creating an account we recommend also installing the Gitpod browser extension. This extension integrates extra functionality in websites such as Github.
 
 1. Go to our [Github repository](https://github.com/thegreenwebfoundation/admin-portal) and click on the Gitpod button if you have the browser extention installed or manually create and link it in your Gitpod Workspaces. It might take a couple of minutes to prepare the environment.
+
 2. After Gitpod is finished preparing the environment, it will open the workspace. Close any unnecessary terminal windows. To open a new fresh terminal window press ```Ctrl + ` ```.
+
+3. In almost all cases, you will need to have a _virtual environment_ set up so that the necessary commands for Django and other libraries are available to you. You can enter a virtual environment by typing `source .venv/bin/activate` from the the project root (i.e. `/workspace/admin-portal/`). You can tell you're a virtual environment - because your prompt will change from `gitpod /workspace/admin-portal (BRANCH_NAME) $` to `(.venv) gitpod /workspace/admin-portal (BRANCH_NAME) $`.

+4. There is a makefile set up to allow easy access to common tasks, like running a development server, spinning up tailwind for front end development, creating a superuser and so on. There is tab-completion set up for github - to see the options available, type `make` and hit tab. You should see output like below:
+
+```
+(.venv) gitpod /workspace/admin-portal (BRANCH_NAME) $ make 
+data_analysis_repo    dev.tailwind.start    docker.release        release

+dev.tailwind.install  docker.build          notebook.gitpod       venv

 ## Development on a local machine using virtual environments
 In an isolated [virtual environment](https://docs.python.org/3/tutorial/venv.html) we are able to easily manage Python dependencies within the project.
