+# List The Files Being Loaded By Mise
+
+While running `mise` for the first time, after adding a `mise.toml` file to a
+project, I noticed something strange. Instead of invoking the command I had
+specified (`mise run dev`), several parellel tool downloads were kicked off. In
+addition to Ruby, it was installing an older version of Postgres, and lua. What
+gives?
+
+By running `mise cfg`, I can list all the files being loaded by `mise` and get
+to the bottom of this.
+
+```bash
+mise cfg
+
+Path                         Tools
+~/.tool-versions             node, ruby, postgres, lua
+~/code/still/.ruby-version   ruby
+~/code/still/Gemfile         (none)
+~/code/still/.tool-versions  ruby
+~/code/still/mise.toml       (none)
+```
+
+I was only thinking about the files local to my project and I forgot that I
+have a system-wide `.tool-versions` file. As we can see from the output, that
+file specifies `postgres` and `lua` as well. Mise wanted to ensure that it had
+downloaded the specified versions of each of those tools before running my
+task.
