+###### Building from Git
+
+Use the `scripts/build_git_archive.sh` script to build a git archive. Eg.:
+
+```shell
+> ./scripts/build_git_archive.sh -c 90bd2fb92783468f19852140d0080cc2273fa385
+Building archive version '4.15.1' from commit '90bd2fb92783468f19852140d0080cc2273fa385'.

+datovka-4.15.1.9999.20200716.140039.90bd2fb92783468f.tar.xz
+```
+
+Once the source archive is available use the `-v` parameter to pass the package version (here it is `4.15.1.9999.20200716.140039.90bd2fb92783468f`) to build package bundles:
+
+```shell
+> ./scripts/build_windows_bundle.sh -v 4.15.1.9999.20200716.140039.90bd2fb92783468f -p
+```
+```shell
+> ./scripts/build_windows_bundle.sh -v 4.15.1.9999.20200716.140039.90bd2fb92783468f -p --portable-data
