+# Installing the tested pipeline stack
+
+Conda (miniconda3 or anaconda3) must already be installed, if it is not,
+'Advance Setup' below.
+All steps must be performed in bash or a compatible shell.
+
+A fresh installation of Anaconda3 or Miniconda3 is not required for each JWSTDP
+release. The method described here allows for multiple, entirely segregated,
+pipeline installations.
+
+# Advance setup
+ 
+If conda has not yet been installed, use the following steps to obtain
+it, then use the procedure above to install the pipeline software.
+
+For detailed instructions of this step, please visit: http://docs.continuum.io/anaconda/install#linux-install
+
+**For Miniconda:**
+
+```
+$ wget
+https://repo.continuum.io/miniconda/Miniconda3-Latest-Linux-x86_64.sh
+$ bash Miniconda3-Latest-Linux-x86_64.sh
+$ export PATH=$HOME/miniconda3/bin:$PATH
+```
+
+**For Anaconda (if preferred):**
+
+```
+$ wget
+https://repo.continuum.io/archive/Anaconda3-2019.10-Linux-x86_64.sh
+$ bash Anaconda3-2019.10-Linux-x86_64.sh
+$ export PATH=$HOME/anaconda3/bin:$PATH
+```
