-# Evergreen Task Timeouts
-
-## Type of timeouts
-
-There are two types of timeouts that [evergreen supports](https://github.com/evergreen-ci/evergreen/wiki/Project-Commands#timeoutupdate):
-
-* **Exec timeout**: The _exec_ timeout is the overall timeout for a task. Once the total runtime for
-a test hits this value, the timeout logic will be triggered. This value is specified by
-**exec_timeout_secs** in the evergreen configuration.
-* **Idle timeout**: The _idle_ timeout is the amount of time in which evergreen will wait for
-output to be created before it considers the task hung and triggers timeout logic. This value
-is specified by **timeout_secs** in the evergreen configuration.
-
-**Note**: In most cases, **exec_timeout** is usually the more useful of the timeouts.
-
-## Setting the timeout for a task
-
-There are a few ways in which the timeout can be determined for a task running in evergreen.
-
-* **Specified in 'etc/evergreen.yml'**: Timeout can be specified directly in the 'evergreen.yml' file,
-both on tasks and build variants. This can be useful for setting default timeout values, but is limited
-since different build variants frequently have different runtime characteristics and it is not possible
-to set timeouts for a task running on a specific build variant.
-
-* **etc/evergreen_timeouts.yml**: The 'etc/evergreen_timeouts.yml' file for overriding timeouts
-for specific tasks on specific build variants. This provides a work-around for the limitations of
-specifying the timeouts directly in the 'evergreen.yml'. In order to use this method, the task
-must run the "determine task timeout" and "update task timeout expansions" functions at the beginning
-of the task evergreen definition. Most resmoke tasks already do this.
-
-* **buildscripts/evergreen_task_timeout.py**: This is the script that reads the 'etc/evergreen_timeouts.yml'
-file and calculates the timeout to use. Additionally, it will check the historic test results of the
-task being run and see if there is enough information to calculate timeouts based on that. It can
-also be used for more advanced ways of determining timeouts (e.g. the script is used to set much
-more aggressive timeouts on tasks that are run in the commit-queue).
