+# IRB Prints A Helpful Welcome Prompt
+
+I've been using `irb` for over 15 years as a REPL for executing Ruby code. It
+has always been pretty plain in a lot of ways. For this reason, I often used
+[`pry`](https://github.com/pry/pry) instead, especially in a Rails context.
+`irb` has gotten notably better in recent years. I was delighted to recently
+notice that earlier this year they landed delightful, colorful, and helpful
+improvement to the welcome prompt.
+
+It looks more or less like this:
+
+```
+❯ irb
+
+⢀⡴⠊⢉⡟⢿  IRB v1.18.0 - Ruby 3.4.4
+⣎⣀⣴⡋⡟⣻  "ls [object] -g pattern" to filter methods and properties
+⣟⣼⣱⣽⣟⣾  ~/dev/jbranchaud/pool-league-pro
+
+irb(main):001>
+```
+
+Notice it includes a random tip on the second line. I had no idea you could
+include `-g pattern` with an `ls`, so that will likely be landing as a new TIL
+soon.
+
+This improved welcome message has been available since `1.18.0` and originated
+in [this PR](https://github.com/ruby/irb/pull/1183).
