-> We use caching to decrease the load on our servers (see <https://github.com/anuraghazra/github-readme-stats/issues/1471#issuecomment-1271551425>). Our cards have the following default cache hours: stats card - 24 hours, top languages card - 144 hours (6 days), pin card - 240 hours (10 days), gist card - 48 hours (2 days), and wakatime card - 24 hours. If you want the data on your cards to be updated more often you can [deploy your own instance](deploy.md) and set [environment variable](deploy.md#available-environment-variables) `CACHE_SECONDS` to a value of your choosing.
