| - | * //Miniconda3// is a minimal python environment/distribution that can be used for creating more complete work environments.

It will basically make a recent ''conda'' command available on your computer, and you can then use this ''conda'' to create independent Python distributions, where you can install and update Python packages and their dependencies. |
| - | * A python //environment// is basically where you install python. A python //distribution// is the collection of packages you have chosen to install together in the environment. | + | * A conda //environment// is basically where you install the Python that you will use (independently of //Miniconda3// itself). A python //distribution// is the collection of packages you have chosen to install together in this environment. |

| * The way you do things will depend on how you are going to use python. There may be some slight differences if you are installing the environment just for you, or if you need a more stable environment because you are installing for multiple users. | * The way you do things will depend on how you are going to use python.
