# Installing

A fresh installation of Anaconda3 or Miniconda3 is not required for each DE release. The method described here allows for multiple, entirely segregated, pipeline installations.

For existing Anaconda3 or Miniconda3 installations:

```
$ conda env create -n de-d --file http://ssb.stsci.edu/releases/de/d/latest-linux.yml
```

As bugfixes are announced your current pipeline software may be updated by issuing the command:

```
$ conda env update -n de-d --file http://ssb.stsci.edu/releases/de/d/latest-linux.yml
```

# Installing From Scratch

$ export PATH=$HOME/miniconda3/bin:$PATH
```

**For Anaconda (if preferred):**

```
