+
+If you're using SBT, add the following line to your build file:
+
+```scala
+resolvers += "jitpack" at "https://jitpack.io"
+
+libraryDependencies += "com.github.nikdon" % "ranola" % "v0.1.0"
+
+```
+
+For Maven:
+
+```maven
+<repository>
+    <id>jitpack.io</id>
+    <url>https://jitpack.io</url>
+</repository>
+
+<dependency>

 ##  Randomized schemes
 
 1. Generic scheme ([§4.1][1]) is designed for solving the fixed-rank problem, where the target rank of the input matrix is specified in advance. This algorithm works well for matrices whose singular values exhibit some decay, but they may produce a poor basis when the input matrix has a flat singular spectrum or when the input matrix is very large.
