• The title of the pull request is Add/Update/Remove `username/repo` (notice the backticks around `username/repo`) when adding a new plugin.
• The description doesn't mention that it's a Neovim plugin, it's obvious from the rest of the document. No mentions of the word plugin unless it's related to something else.
• The description doesn't contain emojis.
• Neovim is spelled as Neovim (not nvim, NeoVim or neovim), Vim is spelled as Vim (capitalized), Lua is spelled as Lua (capitalized), Tree-sitter is spelled as Tree-sitter.
• Acronyms should be fully capitalized, for example LSP, TS, YAML, etc.
