+
+## How often does Packagist crawl newly added packages?
+
+New packages will be crawled **within ten minutes**.
+
+
+## How often does Packagist crawl existing packages?
+
+Existing packages will be crawled **every hour**.
+
+
+## How often does the Packagist search index update?
+
+The search index is updated **every five minutes**. It will index (or reindex)
+any package that has been crawled since the last time the search
+indexer ran.
+
+
+## Can Packagist be triggered to recrawl a package (on commit or by other means)?
+
+Not yet. :) See [#84](https://github.com/composer/packagist/issues/84).
