# Installation
## Conda (Recommended)
Drizzlepac is installed when you install the stenv conda environment (a replacement for astroconda). Select your desired release and follow the instructions on the [stenv installation page](https://stenv.readthedocs.io/en/latest/getting_started.html).
## Install with pip
`bash $ pip install git+https://github.com/spacetelescope/drizzlepac.git ` The option –no-use-pep517 MAY be required in order to correctly build the C extensions with pip versions up to 22.2, after commenting out the build-backend from the pyproject.toml config file.
Support for installing using pip is still evolving, so use of this command is provided on an experimental basis for now.
## From Source
### Clone this repository `bash $ git clone https://github.com/spacetelescope/drizzlepac $ cd drizzlepac `
### Build the documentation
Note: If you intend to use drizzlepac’s embedded help feature from within an interactive python or ipython session, we recommend you do not skip this step.
`bash $ cd doc/ $ make html `
### Install DrizzlePac
`bash $ python setup.py install `
