+# Apollo master Quick Start Guide
+
+The following guide serves as a user manual for launching the Apollo upgraded software and hardware stack on vehicle.
+
+## Software Installation
+
+### Start apollo-dev docker container
+
+We start apollo-dev docker container following the convention in previous apollo releases.
+
+```
+bash docker/scripts/dev_start.sh
+```
+
+### Enter apollo-dev docker container
+```
+bash docker/scripts/dev_into.sh
+```
+
+### Configure custom settings
+The first time you get into apollo-dev container named `apollo_dev_${USER}`,
+please run apollo bootstrap command as follows:
+```
+bash ./apollo.sh config
+```
+
+> Experimental:
+ There is also an *interactive* mode of bootstraping by running
+ `bash apollo.sh config --interactive` or `bash apollo.sh config -i`.
+ For now, this functionality is incomplete.
+
+### Build modules
+
+Run the following command to build all modules
+```
+bash apollo.sh build
+```
+
+Run the following to build individual modules
+```
+bash apollo.sh build cyber # OR
+bash apollo.sh build planning # OR
+bash apollo.sh build perception
+```
+
+By default, `apollo.sh build` generates debug outputs.
+
+To run optimization build,  just substitute `build` with `build_opt` in the examples above.
+
+### Test modules
+
+```
+bash apollo.sh test # To run unit-tests in all modules including cyber.
+bash apollo.sh test cyber # run all unit-tests for cyber
+bash apollo.sh test --config=gpu prediction # run all unit-test for the prediction module
+```
+
+### Build/Test: An Insider's View
+
+Please note also that when it comes to build/test, `apollo.sh` runs
+`scripts/apollo_build.sh` and `scripts/apollo_test.sh` respectively, both of
+which are just simple wrapper around `bazel build` and `bazel test` commands.
+
+So if you are familiar with bazel, you can run the following to build and test any targets:
+
+```
+bazel build //cyber/...
+bazel test --config=gpu //modules/localization/...
+bazel test //cyber/common:file_test
+```
+
+### Running lint
+
+```
+bash apollo.sh lint
+```
+
+### Bazel x Apollo
+
+The bazel version pre-installed in our cyber/dev docker images is 3.2.0+.
+And the default `--distdir` destination is under
+`${APOLLO_ROOT_DIR}/.cache/distdir`.
