+## Execution Timeout
+
+A workflow times out and gets canceled after this time (in seconds). If the workflow is executed in the main process, a soft timeout is executed (takes effect after the current node finishes). If a workflow is running in its own process, a soft timeout is tried first. The process is killed after waiting for an additional fifth of the given timeout duration.
+
+By default `EXECUTIONS_TIMEOUT` is set to `-1`. For example, if you want to set the timeout to one hour:
+
+```bash
+export EXECUTIONS_TIMEOUT=3600
+```
+
+You can also set maximum execution time (in seconds) for each workflow individually. For example, if you want to set maximum execution time to two hours:
+
+```bash
+export EXECUTIONS_TIMEOUT_MAX=7200
+```
+
+
+## Prune Data
+
+It is possible to prune the execution data. This prevents exceeding the database's capacity and keeping its size moderate. The execution data gets pruned regularly (default: 1-hour interval). All saved execution data older than the max-age will be deleted. To delete data of past executions on a rolling basis:
+
+```bash
+export EXECUTIONS_DATA_PRUNE=true
+```
+
+You can also set how old (in hours) the execution data has to be to get deleted.
+
+```bash
+export EXECUTIONS_DATA_MAX_AGE=672
+```
+
+You can also set the timeout (in seconds) after execution data has been pruned.
+
+```bash
+export EXECUTIONS_DATA_PRUNE_TIMEOUT=7200

+It is also possible to set default values for credentials. These credentials get automatically prefilled. To set default credentials, use the following format.

 ## Configuration via file
 
 It is also possible to configure n8n using a configuration file.
