 Therefore, if the bits of the hash value are permuted accordingly, compatibility can be achieved.
 
 ## File hashing
+This library contains an implementation of [ImoHash](https://github.com/kalafut/imohash) that
+allows fast hashing of files.
+It is based on the idea of hashing only the beginning,
+a middle part and the end, of large files,
+which is usually sufficient to distinguish files.
+Unlike cryptographic hashing algorithms, this method is not suitable for verifying the integrity of files.
+However, this algorithm can be useful for file indexes, for example, to find identical files.
 
 ### Usage
 ```java
 // create some file in the given path
 File file = path.resolve("test.txt").toFile();
-try (FileWriter myWriter = new FileWriter(file)) {
-  myWriter.write("this is the file content");
+try (FileWriter fileWriter = new FileWriter(file)) {
+    fileWriter.write("this is the file content");
 }
 
 // use ImoHash to hash that file

 ## Consistent hashing
+This library contains an implementation of [JumpHash](https://arxiv.org/abs/1406.2294)
+that can be used to achieve distributed agreement when assigning hash values to a given number of buckets.
+The hash values are distributed uniformly over the buckets.
+The algorithm also minimizes the number of reassignments needed for balancing when the number of buckets changes.
