In the swapiness documentation, install instructions are repeated

https://developer.couchbase.com/documentation/server/current/install/install-swap-space.html

On this page, the instructions for setting swapiness are repeated, I believe the first set of instructions that has the code snippets is clearer, but it is confusing that it tells you again how to change swapiness right after. I thought at first I had to do more than just follow the code snippets, but the code snippets actually encompass the latter instructions.
