+1. Install XeLaTeX, latexmk, GNU Make, and GhostScript packages;
+2. Install [Font Awesome 5](#font-awesome-5) and
+   other [required fonts](#required-fonts);
+3. Replace `resume-zh.tex` and `resume-en.tex` with your versions;
+4. Compile to PDFs with a simple `make` :-)

+**NOTE**:
+The `TEXINPUTS` environment variable is set in the [Makefile](Makefile#L10)
+so that XeLaTeX can find the `resume.cls` template and `fontawesome5.sty`
+package.  If you don't or can't use this `Makefile`, e.g., on Windows,
+then you need to appropriately configure your environment.

+**NOTE**:
+I use Windows only a bit, so I don't have a guide to use this template on
+Windows.  I'm glad to accept suggestions and updates.
