-> The API has shifted to version 2, thereby naturally introducing breaking changes. If you'd want to use the previous version of this API, then refer to [the last stable version](https://github.com/ghoshRitesh12/aniwatch-api/tree/v1.40.0).

 ### Custom HTTP Headers
+
 Currently this API supports parsing of only one custom header, and more may be implemented in the future to accommodate varying needs.
 
 - `X-ANIWATCH-CACHE-EXPIRY`: this custom header is used to specify the cache expiration duration in **seconds** (defaults to 60 if the header is missing). The `ANIWATCH_API_REDIS_CONN_URL` env is required for this custom header to function as intended; otherwise, there's no point in setting this custom header.
 
 ### Environment Variables
 
-More info can be found in the [`.env.example`](https://github.com/ghoshRitesh12/aniwatch-api/blob/main/.env.example) file, where envs' having a value that is contained within `<` `>` angled brackets are just examples and should be replaced with relevant ones.

 - `ANIWATCH_API_VERCEL_DEPLOYMENT`: required for distinguishing Vercel deployment from other ones; set it to true or any other non-zero value.
 - `ANIWATCH_API_HOSTNAME`: set this to your api instance's hostname to enable rate limiting, don't have this value if you don't wish to rate limit.
 - `ANIWATCH_API_REDIS_CONN_URL`: this env is optional by default and can be set to utilize Redis caching functionality. It has to be a valid connection URL; otherwise, the Redis client can throw unexpected errors.
+- `ANIWATCH_API_S_MAXAGE`: specifies the maximum amount of time (in seconds) a resource is considered fresh when served by a CDN cache.
