I don't know anything about neovim (except having been a vim user before) but I thought I'd give it a try. I'm having trouble getting to the bit where I'm evaluating Clojure code using the directions here: https://practical.li/neovim/configuration/astronvim/
$ cd ~/.config/astronim/
$ ag conjure .
<nil>
think_beretInstalling (clone) both the AstroNvim and Practicalli AstroNvim (user) config will provide Conjure, although you will need to run Neovim with that config once to install all the plugins (should happen automatically) or can be run using SPC p a
AtstroNvum has a Clojure pack in the AstroNvim community, which I added via the Preacticalli AstroNvim user config (as it's not a default plugging for AstroNvim)
The plugins are not added to the configuration files, they should be in a user cache location, e.g on Linux the plugin files are
