+### Stdout
+
+- Added `stdout` mode which allows you to fetch info in a plain text format that works<br \>
+with lemonbar and in your scripts. You can use it by launching fetch with `--stdout` to print all functions enabled<br \>
+in your `printinfo` function. You can selectively print functions by passing arguments to `--stdout`<br \>
+like so:
+
+```sh
+# Print the output of all info functions enabled in printinfo
+fetch --stdout
+
+# Print the output of memory
+fetch --stdout memory
+
+# Print the output of memory and disk
+fetch --stdout disk
+
+```
+
+- Added `--stdout_seperator` and `$stdout_seperator` which takes a string and adds it<br \>
+as a seperator between the output.
+- Added `--stdout_title` and `$stdout_title` which allow you to toggle the `title@hostname`<br \>
+from appearing in the output.
+- Added `--stdout_subtitles` which allow you to toggle the `Info:` titles from appearing in<br \>
+the output.
+
+```sh
+# Hiding subtitles
+fetch --stdout --stdout_subtitles off
+
+# Custom seperator
+fetch --stdout disk gpu --stdout_seperator "  |  "
+
+```
+
+**NOTE:** `stdout_subtitles` and `stdout_title` only work when `--stdout` is used on its own.
+
 ### Info
 
 - You can now display info without a subtitle. eg. `info memory`
