+You need to configure python3 and pip first.
+
+```shell
+pip install mkdocs-material mkdocs-static-i18n
+```
+
+##### Run the site locally
+
+```shell
+mkdocs serve
+```
+
+or
+
+```shell
+python3 -m mkdocs serve
+```
+
+#### For the project
+
+By default you have the latest Go installed (currently 1.19), and added `GOPATH/bin` to the PATH environment variable.
+
+##### Setup
