-## Src code
+## src code
 
 There are two src codes within this repository [mesh_generator](./src/mesh_generator/) and [poisson](./src/poisson/). These are designed to work together. 
-- `mesh_generator` generates a basic square 2D traiangular mesh (see [mesh_generator.f90](./src/mesh_generator/mesh_generator.f90) for more details).
+- `mesh_generator` generates a basic square 2D triangular mesh (see [mesh_generator.f90](./src/mesh_generator/mesh_generator.f90) for more details).
 - `poisson` is a solver which finds the solution of the steady-state heat conduction equation represented by the Poisson equation over a 2D traingular mesh (see [poisson.f90](./src/poisson/poisson.f90) for more details).
