+# New Spec
+
+For new LSP, add in `lua/modules/language-specs.lua` at `lsp = <name>`.
+Name should match the mason registry one at: `https://github.com/mason-org/mason-registry/tree/main/packages`
+
+1. Run `nvim --headless +InstallAll +qa` (it invalidates cache automatically)
+2. Run ` nvim --headless +FetchLspConfigs +qa` -> It will download the nvim-lspconfig variant in `lsp/`
+
+You may need to run: `pkill prettierd` (as it is running in background)
+
+# Other commands
+
+```
+nvim --headless +Sync +qa # For packages/plugins
+```
