+# Parcel
+
+Parcel is a (currently experimental) parser generator.
+
+## Building
+
+Parcel has very few dependencies. Below, there's a list of those
+dependencies that Parcel has:
+
+- `gcc` (no other compiler is supported)
+- binutils (`ar`, `1d`, ...)
+- `bash`
+- *The Usual* (a *libc*, the *system headers*, ...)
+
+To build Parcel, navigate to the repository's root directory
+and type the command below. It will perform all compiler calls
+and create the code archive at *.build/libparcel.a* .
+
+```bash
+./build.bash release
+```
+
+### Debug Builds
+
+For development, there are two other important commands, the first of
+which being for compiling the library with debug information.
+
+```bash
+./build.bash debug
+```
+
+The second command builds the manual checks which are located in
+the sub-folder `checks/`.
+
+```bash
+./build.bash checks
+```
+
