 ### Setting up `NNN_FIFO`
 
 Every plugins use `NNN_FIFO`, so it needs to be exported. You can either:
-1. Globally export a FIFO path in, e.g., `.profile`:
-   ~~~sh
-   export NNN_FIFO=/tmp/nnn.fifo
-   ~~~
-   In that case every `nnn` instance will use the same FIFO, so a previewer plugin will get updated from every cursor move from any instance in the same window.
-2. If you want to avoid that behaviour, you need to use a different FIFO path for every instance, e.g. with an alias:
-   ~~~sh
-   alias nnn='NNN_FIFO="$(mktemp -u)" nnn'
-   ~~~
 
-Not that you don't need to create the FIFO file, `nnn` will create it itself.

+   ```sh
+   export NNN_FIFO=/tmp/nnn.fifo
+   ```
+
+   This mechanism is suitable if you are using a single instance of `nnn`.
+2. For multiple instances of `nnn`, use a different FIFO path for every instance, e.g. with an alias:
+
+   ```sh
+   alias nnn='NNN_FIFO="$(mktemp -u)" nnn'
+   ```

+`nnn` will create the per-instance FIFO files.
