 ## Installation
 
 Please contact the [JWST Help Desk](https://jwsthelp.stsci.edu) for installation issues.
 
 The easiest way to install the latest `jwst` release into a fresh virtualenv or conda environment is
 
-    pip install jwst
+    pip install jwst==1.19.1
 
 ### Detailed Installation
 
@@ -56,22 +58,22 @@ Remember that all conda operations must be done from within a bash/zsh shell.
 
 You can install the latest released version via `pip`.  From a bash/zsh shell:
 
-    conda create -n <env_name> python=3.12
+    conda create -n <env_name> python=3.13
     conda activate <env_name>
-    pip install jwst
+    pip install jwst==1.19.1
 
-You can also install a specific version:
-
-    conda create -n <env_name> python=3.12
-    conda activate <env_name>
-    pip install jwst==1.18.1
+If no version tag is specified in the install command, `pip` will find the latest release compatible
+with the current environment. This can lead to an unintended `jwst` version, if the latest release
+of `jwst` is not compatible with your environment's python version. Explicitly setting the version
+in the install command will return an informative error if the latest release is not compatible
+with your environment.
 
 ### Installing the development version from Github
 
 You can install the latest development version (not as well tested) from the
 Github main branch:
 
-    conda create -n <env_name> python=3.12
+    conda create -n <env_name> python=3.13
     conda activate <env_name>
