 /* The Redis HyperLogLog implementation is based on the following ideas:
  *
- * * The use of a 64 bit hash function as proposed in [1], in order to don't
- *   limited to cardinalities up to 10^9, at the cost of just 1 additional
- *   bit per register.
+ * * The use of a 64 bit hash function as proposed in [1], in order to estimate
+ *   cardinalities larger than 10^9, at the cost of just 1 additional bit per
+ *   register.
  * * The use of 16384 6-bit registers for a great level of accuracy, using
  *   a total of 12k per key.
  * * The use of the Redis string data type. No new type is introduced.
