 To use a development version of this package, you can choose one of the following methods:
 
 1. **Change the UUID in the project file and load the package:**
-   This approach will produce warnings and may lead to method ambiguities between the development version and the one in the sysimage, but it can be used for basic experimentation.
+
+   Change the UUID line in `Project.toml` as
+   ```diff
+   - uuid = "37e2e46d-f89d-539d-b4ee-838fcccc9c8e"
+   + uuid = "27e2e46d-f89d-539d-b4ee-838fcccc9c8e"
+   ```
+
+   Start `julia` as
+   ```console
+   JULIA_PRUNE_OLD_LA=true julia +nightly --compiled-modules=existing --project
+   ```
+   where it is assumed that one is already within the `LinearAlgebra` directory (otherwise, adjust
+   the project path accordingly). The `julia +nightly` command above assumes that `juliaup` is being used
+   to launch `julia`, but one may substitute this with the path to the julia executable.
+
+   Within the `julia` session, load the `LinearAlgebra` module after pruning the one in the sysimage. This may be done as
+   ```julia
+   include("test/prune_old_LA.jl") && using LinearAlgebra
+   ```
+
+   Note that loading the test files in the REPL will automatically carry out the pruning to ensure that the development version of the package is used in the tests.
+
+   If you are contributing to the repo using this method, it may be convenient to ignore the local changes to `Project.toml` by running
+   ```console
+   git update-index --skip-worktree Project.toml
+   ```
 
 2. **Build Julia with the custom `LinearAlgebra` commit:**
-   Modify the commit in `stdlib/LinearAlgebra.version` and build Julia.
+
+   Modify the commit in [`stdlib/LinearAlgebra.version`](https://github.com/JuliaLang/julia/blob/master/stdlib/LinearAlgebra.version) and build Julia. This requires one to push the development branch
+   to `GitHub` or an equivalent platform.
 
 3. **Build a custom sysimage with the new `LinearAlgebra`:**
    - Install `PackageCompiler`.
