\$z=2\$ (XLS-\$z2\$). XLS-\$z2\$ is a deep spectroscopic survey of 35
Lyman-\${\textbackslash}alpha\$ emitters (LAEs) utilising \${\textbackslash}approx90\$ hours of exposure
time with VLT/X-SHOOTER and covers rest-frame Ly\${\textbackslash}alpha\$ to H\${\textbackslash}alpha\$
emission with R\${\textbackslash}approx4000\$. We present the sample selection, the
observations and the data reduction. Systemic redshifts are measured
from rest-frame optical lines for 33/35 sources. In the stacked
spectrum, our LAEs are characterised by an interstellar medium with
little dust, a low metallicity and a high ionisation state. The ionising
sources are young hot stars that power strong emission-lines in the
optical and high ionisation lines in the UV. The LAEs exhibit clumpy UV
morphologies and have outflowing kinematics with blue-shifted SiII
absorption, a broad [OIII] component and a red-skewed Ly\${\textbackslash}alpha\$ line.
Typically 30 \% of the Ly\${\textbackslash}alpha\$ photons escape, of which one quarter on
the blue side of the systemic velocity. A fraction of Ly\${\textbackslash}alpha\$ photons
escapes directly at the systemic suggesting clear channels enabling a
\${\textbackslash}approx10\$ \% escape of ionising photons, consistent with an inference
based on MgII. A combination of a low effective HI column density, a low
dust content and young star-burst determine whether a star forming
galaxy is observed as a LAE. The first is possibly related to outflows
and/or a fortunate viewing angle, while we find that the latter two in
LAEs are typical for their stellar mass of 10\${\textasciicircum}9\$ M\$\_\{{\textbackslash}odot\}\$.},
