 * `GRAPHQL_CACHE` -  Should the query cache be enabled? Default: `false`
 * `GRAPHQL_CACHE_TTL` -  Cache TTL in seconds for SELECT type of queries. Default: `5`
 * `LOG_LEVEL` - Logging level. Default: `info`
+* `RETRIES_ENABLE` - Should retries be enabled? Default: `false`
+* `RETRIES_NUMBER` - Number of retries: Default: `1`
+* `RETRIES_DELAY` - Delay in retries in milliseconds. Default: `250`
+
+### Cache
+
+You have two options to enable the cache:
+
+* Use `GRAPHQL_CACHE` environment variable which will enable the cache globally. It may be desired if you want to use the cache for all queries.
+* Add `gqlcache: true` header for your query which will enable the cache for this query only with `GRAPHQL_CACHE_TTL` TTL.
+
+Example:
+
+```go
+headers := map[string]interface{}{
+  ...
+  "gqlcache": true,
