+## QGIS RPM generator
+
+### Build RPM using mock
+
+```bash
+$ ./buildrpms.sh
+```
+
+### Generate a valid spec file from template
+
+```bash
+$ ./buildrpms.sh -c
+```
+
+### Build SRPM using mock
+
+```bash
+$ ./buildrpms.sh -s
+```
+
+### Rebuild last generated RPM using mock
+
+```bash
+$ ./buildrpms.sh -b
+```
+
+### Build an unstable release
+
+```bash
+$ ./buildrpms.sh [flags] -u
+```
+
+This generates an RPM with release `.git<short commit ID>`
+
+
+### MOCK old chroot
+
+It is possible to execute `mock` using the 'old chroot' behaviour (which does not uses `systemd-nspawn`) setting
+the environment variable `_MOCK_OLD_CHROOT` before running `buildrpms.sh`:
+
+```bash
+export _MOCK_OLD_CHROOT=1
+```
+
+This may be useful when running `mock` inside environments that do not play well with `systemd-nspawn` (LXC/LXD, Docker...).
