 ====== Cloning From Github ======
-Although you can make your own [[Components:Element]]s just by installing pre-built packages, to participate in the development of MFM or ULAM you will need to download and build the software from its source codes, which are kept in two repositories at Github.
+**NOTE**: You can compile and run your own [[Components:Element]]s just using the pre-built packages, as shown [[dev:install_ulam|here]]; the instructions on this page are **not needed** for that.
-Cloning the repo from Github seems relatively straight forward, but there are some dependencies that need to be installed in order to get the source to build. Here is a full tutorial describing how to build the MFM software from the source.

 Note this will create MFM/ and ULAM/ directories as siblings in whatever directory you started in -- and that's desirable because the two repositories will be able to find each other without any additional local configuration.

+Now that you have installed all of the dependencies that you need, you can build the MFM software:
+<code>
+$ cd MFM
+MFM$ make
+</code>
+This should build the MFM software as long as the repo does not contain any errors.  Depending on your machine, the build may take quite a while.
+After that succeeds, you can build the ULAM compiler:
 <code>
-make

+Once the ULAM compiler is built, you need to use it to build "ulam exports" -- various libraries and demos that are part of the system:

+</code>
+Note that the results of making ulamexports (in the ULAM/ repo) places its output in the MFM/ repo!  Trying to run the MFM simulator without getting through 'ulamexports' successfully is unlikely to work!
+Note also that ''make ulamexports'' might take a //very// long time.
