-# Bazel build container
-
-This container enables running Bazel inside a container, with the host cache mounted.
-
-To use the container, run
-
-```shell
-source container.sh
-startBazelServer
-```
-
-You can then execute Bazel commands like you normally would do, as the sourced `bazel`
-function shadows binaries you might have in your path:
-
-```shell
-bazel query //...
-```
-
-To terminate the container, which is running as daemon in the background, execute
-
-```shell
-stopBazelServer
-```
