+## Using a local Git mirror
+
+To speed up builds, it is possible to use a local mirror by changing
+the repository URL:
+```env
+EBUILD_SRC_REPO=http://local-mirror:8080/EdgeTX/edgetx
+```
+
+[cloudbuild-mirror](https://github.com/EdgeTX/cloudbuild-mirror) can be
+used as a local mirror. It also supports automatic refreshing of the
+targets (see next section).
+
+With this configuration only, the submodules will still be fetched from `http://github.com`,
+as the full URL is encoded into the respective `.gitmodules` files. Fortunately, Git offers
+a simple to override this with [insteadOf](https://git-scm.com/docs/git-config#Documentation/git-config.txt-urlbaseinsteadOf).
+
+Just mount this file into the workers at `/etc/gitconfig`:
+```
+[url "http://local-mirror:8080"]
+  insteadOf = https://github.com
+```
+
+## Refresh targets automatically from URL
+
+It is also possible to fetch `targets.json` from a URL instead of a local
+file. In that case, the targets are refreshed automatically (defaults to 5 minutes interval).
+
+```env
+# Use cloudbuild mirrored repository as the source for targets.json
+EBUILD_TARGETS=http://local-mirror:8080/gitweb.cgi?p=EdgeTX/cloudbuild.git;a=blob_plain;f=targets.json;hb=HEAD
+# This is the default refresh interval in seconds
+EBUILD_TARGETS_REFRESH_INTERVAL=300
+```
