+# Treesitter and LSP language parser install
+After configuration, from within nvim, we can proceed to install and activate additional language parsers. This can be done with 
+  - :TSInstall <TAB>
+    And choosing all the language we need. My preferences are:
+  ```
+  :TSInstall javascript c python perl css lua vim bash php regex html awk sql make cmake sql dockerfile json markdown mermaid yaml 
+  ```
+  - Similar action is to be performed for LSP, whose config is managed via mason plugin. Some plugins like sqlls, intelphense, awk-language-server and others) require nodejs javascript modules to be managed via npm, therefore node installation is pre-required at the system level.
