+# Target
+Simulate quasi-1D Josephson dynamics. Initialize the simulation of a unitary Fermi gas confined in an external potential
+```math
+V^{(ext)}_{\sigma}(x) = \frac{1}{2}\omega_x^2 x^2 + V_0e^{-2x^2/w^2} + k x,
+```
+where the first term corresponds to harmonic confinement, the second describes the potential barrier separating the cloud into two reservoirs, and the last introduces a small linear tilt to generate a population imbalance between the left and right reservoirs.
+
+# Step 1: Creating working folders
+We start by copying template folders for static (st) and time-dependent (td) simulations:
+```bash
+cp -r $WSLDA/st-project-template ./st-jj-example
+cp -r $WSLDA/td-project-template ./td-jj-example
+```
+
+# Step 2: Editing files for the static calculations
+## Edit predefines.h
+Select the lattice size and functional, and inspect all other tags that can be relevant for your problem:
+```c
+/**
+ * Define lattice size and lattice spacing.
+ * */
+#define NX (256)
+#define NY (16)
+#define NZ (16)
+// ...
+#define FUNCTIONAL SLDAE
+/**
+ * Sets the effective mass to be equal 1.
+ * */
+#define SLDA_FORCE_A1
+// ...
+```
