 ## Shims vs PATH
 
+The following features are affected when shims are used **instead** of PATH activation:

+- Env vars defined in mise are only available to mise tools
+- Most hooks won't trigger
+- The unix `which` command points to the shim, obscuring the real executable

 In general, I recommend using PATH (`mise activate`) instead of shims for _interactive_ situations. The
 way activate works is every time the prompt is displayed, mise-en-place will determine what PATH and other
 env vars should be and export them. This is why it doesn't work well for non-interactive situations like

 For interactive shells, `mise activate` is recommended. In non-interactive sessions, like CI/CD, IDEs, and scripts, using `shims` might work best. You can also not use any and call `mise exec/run` directly instead.
