 > You must know, The ID generated by the snowflake algorithm is not guaranteed to be unique.
 > For example, when two different requests enter the same node of the same data center at the same time, and the sequence generated by the node is the same, the generated ID will be duplicated.
 
-So if you want to use the snowflake algorithm to generate unique ID, You must ensure: The sequence-number generated in the same millisecond of the same node is unique.
+If you want to use the snowflake algorithm to generate unique ID, You must ensure: The sequence-number generated in the same millisecond of the same node is unique.
 Based on this, we created this package and integrated multiple sequence-number providers into it.
 
 * RandomSequenceResolver (Random)
-* RedisSequenceResolver (based on redis psetex and incrby)
+* FileLockResolver（PHP file lock `fopen/flock`, **Concurrency Safety**）

 * LaravelSequenceResolver (based on redis psetex and incrby)
 * SwooleSequenceResolver (based on swoole_lock)
-* FileLockResolver（PHP file lock `fopen/flock`）
 
 Each provider only needs to ensure that the serial number generated in the same millisecond is different. You can get a unique ID.
