+CONTINUOUS INTEGRATION SCRIPTS
+==============================
+
+Environment Variables Used in Build Scripts
+-------------------------------------------
+
+- `NODE_LABELS`: the variable defines a list of OS properties.  The set values are used by the
+  build scripts to select proper behavior for different OS.
+
+  The list should include at least `[OS_TYPE]`, `[DISTRO_TYPE]`, and `[DISTRO_VERSION]`.
+
+  Possible values for Linux:
+
+  * `[OS_TYPE]`: `Linux`
+  * `[DISTRO_TYPE]`: `Ubuntu`
+  * `[DISTRO_VERSION]`: `Ubuntu-14.04`, `Ubuntu-16.04`
+
+  Possible values for OS X / macOS:
+
+  * `[OS_TYPE]`: `OSX`
+  * `[DISTRO_TYPE]`: `OSX` (can be absent)
+  * `[DISTRO_VERSION]`: `OSX-10.10`, `OSX-10.11`, `OSX-10.12`
+
+- `JOB_NAME`: optional variable to define type of the job.  Depending on the defined job type,
+  the build scripts can perform different tasks.
+
+  Possible values:
+
+  * empty: default build process
+  * `code-coverage` (Linux OS is assumed): debug build with tests and code coverage analysis
+  * `limited-build`: only a single debug build with tests
+
+- `CACHE_DIR`: the variable defines a path to folder containing cached files from previous builds,
+  e.g., a compiled version of ndn-cxx library.  If not set, `/tmp` is used.
+
+- `WAF_JOBS`: number of parallel build jobs used by waf, defaults to 1.
