-## Comparisons to CircleCI’s Re-run with SSH
+## Conditions and Limitations
 
-### Similarities
-
-* 2 hour time limit after job has finished for when SSH sessions will be closed out and runner will return to the regular runner pool
+* **The job must still be running when you ssh into the machine.**  If the job is finished running, you cannot ssh in.
+* Only works on your own PRs.  If you want to ssh into a job running on the main or someone else's job, see the below section about aws ssm.
+* You will be removed from the machine after 2 hours.
+* Only works for users who are connected to the Meta VPN
+  * No current planned support for outside collaborators
 * Public keys for ssh are pulled from Github using `https://github.com/${github.actor}.keys`
     * Example: https://github.com/seemethere.keys
