 ====== Cloning From Github ======
-To make your own [[Components:Element]]s, you will need to download and build the MFM software from source. It is kept on a git repo 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.
+However, if you wish 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.
+Cloning the repos from Github seems relatively straightforward, but there are some dependencies that need to be installed in order to get the source to build.  Here are steps describing how to build MFM and ULAM from their sources.
+**WARNING**: As of Summer 2017, both the MFM and ULAM repos are under heavy development.  Your Mileage May Vary!
 ** Note: ** This tutorial is performed on Ubuntu 14.04 . Your installation procedure may vary.

+Next, you will need to clone the codebase to your computer. To do this, browse to the folder which you would like to contain the repos and clone:

+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.
+===== Build the software =====
+Now that you have installed all of the dependencies that you need, you can build the MFM software:
 <code>
-bin/mfms
+$ cd MFM
+MFM$ make
 </code>
-to run the simulator.
+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>
+MFM$ cd ../ULAM
+ULAM$ make
+</code>
+This may //also// take quite a while.
+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>
+ULAM$ make ulamexports
+</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.
+===== Run the software =====
+To run the software, the executable is located in the **MFM/bin** folder. Type:
+<code>
+MFM$ ./bin/mfms
+</code>
+to run the simulator.
