 It's strongly suggested that you always use the latest image of Fluent Bit.
 
@@ -37,19 +33,19 @@ For every architecture we build the layers using the following base images:
 Download the last stable image from 1.4 series:
 
 ```text
-$ docker pull fluent/fluent-bit:1.4
+$ docker pull fluent/fluent-bit:1.5
 ```
 
 Once the image is in place, now run the following \(useless\) test which makes Fluent Bit measure CPU usage by the container:
 
 ```text
-$ docker run -ti fluent/fluent-bit:1.4 /fluent-bit/bin/fluent-bit -i cpu -o stdout -f 1
+$ docker run -ti fluent/fluent-bit:1.5 /fluent-bit/bin/fluent-bit -i cpu -o stdout -f 1
 ```
 
 That command will let Fluent Bit measure CPU usage every second and flush the results to the standard output, e.g:
 
 ```text
-Fluent-Bit v1.4.x
+Fluent-Bit v1.5.x
