-What inspired me to write vimux was [tslime.vim](https://github.com/kikijump/tslime.vim), a plugin that lets you send input to tmux. While tslime.vim works well, I felt it wasn't optimized for my primary use case which was having a smaller tmux pane that I would use to run tests or play with a REPL.
+Vimux was originally inspired by [tslime.vim](https://github.com/jgdavey/tslime.vim/network), a plugin that lets you send input to tmux. While tslime.vim works well, it wasn't optimized for the use case of having a smaller tmux pane used to run tests or play with a REPL. The goal of Vimux is to make interacting with tmux from vim effortless.
 
-My goal with vimux is to make interacting with tmux from vim effortless. By default when you call `VimuxRunCommand` vimux will create a 20% tall horizontal pane under your current tmux pane and execute a command in it without losing focus of vim. Once that pane exists whenever you call `VimuxRunCommand` again the command will be executed in that pane. As I was using vimux myself I wanted to rerun commands over and over. An example of this was running the current file through rspec. Rather than typing that over and over I wrote `VimuxRunLastCommand` that will execute the last command you called with `VimuxRunCommand`.
