Hi, I downloaded your template and following the documentation I removed the gulp package using npm (I use node vers. 14.17.5 and npm vers. 6.14.14). Still through npn I installed gulp-cli (vers. 2.3.0) global local unknown. I continued with the installation of the necessary modules always with npm, here I am returned an error and I did not go ahead. I copy below the logo generated by npn 2157 verbose stack Error: Command failed: git checkout 4.0 2157 verbose stack error: pathspec ‘4.0’ did not match any file(s) known to git 2157 verbose stack 2157 verbose stack at ChildProcess.exithandler (child_process.js:390:12) 2157 verbose stack at ChildProcess.emit (events.js:400:28) 2157 verbose stack at maybeClose (internal/child_process.js:1055:16) 2157 verbose stack at Process.ChildProcess._handle.onexit (internal/child_process.js:288:5) 2158 verbose cwd C:\Lavori\Roxor\lisciani\tiketing\grafica\paper-knowledge-base-bootstrap4-html-template\paper-knowledgebase-all-files\paper-knowledgebase\development-version 2159 verbose Windows_NT 10.0.19044 2160 verbose argv “C:\\Program Files\\nodejs\\node.exe” “C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js” “install” 2161 verbose node v14.17.5 2162 verbose npm v6.14.14 2163 error code 1 2164 error Command failed: git checkout 4.0 2164 error error: pathspec ‘4.0’ did not match any file(s) known to git 2165 verbose exit [ 1, true ]

Nice layout. It would be nice if the LEFT NAV on this page would not scroll vertically so it is always visible when the page scrolls. https://xvelopers.com/demos/html/paper-knowledgebase-1.0.0/documentations.html
