The rest-frame UV recombination emission line Ly$\alpha$ can be powered byionising photons from young massive stars in star forming galaxies, but itsability to be resonantly scattered by neutral gas complicates itsinterpretation. For reionization era galaxies, a neutral intergalactic medium(IGM) will scatter Ly$\alpha$ from the line of sight, making Ly$\alpha$ auseful probe of the neutral fraction evolution. Here, we explore Ly$\alpha$ inJWST/NIRSpec spectra from the ongoing JADES programme, which targets hundredsof galaxies in the well-studied GOODS-S and GOODS-N fields. These sources areUV-faint ($-20.4<\rm M_{\rm UV}<-16.4$), and thus represent a poorly-exploredclass of galaxies. The low spectral resolution ($R\sim100$) spectra of a subsetof 84 galaxies in GOODS-S with $z_{spec}>5.6$ (as derived with optical lines)are fit with line and continuum models, in order to search for significant lineemission. Through exploration of the R100 data, we find evidence for Ly$\alpha$in 17 sources. This sample allows us to place observational constraints on thefraction of galaxies with Ly$\alpha$ emission in the redshift range$5.6<z<7.5$, with a decrease from $z=6$ to $z=7$. We also find a positivecorrelation between Ly$\alpha$ equivalent width and M$_{UV}$, as seen in othersamples. These results are used to estimate the neutral gas fraction at$z\sim7$, agreeing with previous results ($X_{HI}\sim0.5-0.9$).
