 > [!IMPORTANT]
 > **Do not trigger multiple crawl jobs that reference the same index simultaneously.**
 A single crawl execution can be thought of as a single crawler.
 Even if two crawl executions share a configuration file, the two crawl processes will not communicate with each other.
 Two crawlers simultaneously interacting with a single index can lead to data loss.

-1. Clone the repository: `git clone https://github.com/elastic/crawler.git`

-   - `-i` allows the container to stay alive so CLI commands can be executed inside it
-   - `-d` allows the container to run "detached" so you don't have to dedicate a terminal window to it
-   - `--network` if you're running Elasticsearch in another docker container on the same machine, they will both need to run on the same network
-5. Confirm that CLI commands are working `docker exec -it crawler bin/crawler version`
-   - Execute other CLI commands from outside of the container by prepending `docker exec -it crawler <command>`
-6. Create a config file for your crawler. See [Configuring crawlers](#configuring-crawlers) for next steps.

 Crawler can be configured using two config files, a Crawler configuration and an Elasticsearch configuration.
 The Elasticsearch configuration file is optional.
 It exists to allow users with multiple crawlers to only need a single Elasticsearch configuration.
 See [CONFIG.md](docs/CONFIG.md) for more details on these files.
 
+### Running a Crawl Job
+
+Once everything is configured, you can run a crawl job using the CLI:

 ### Scheduling Recurring Crawl Jobs
 
 Crawl jobs can also be scheduled to recur.
