+# EPICS Modules
+
+Modules are libraries based on EPICS base that are designed to be used by IOC applications. They may include support for different types of hardware, general utilities for the IOC engineers, new record types and plenty more.
+
+The general convention for modules is that they will live in the `modules` directory under a particular EPICS installation.
+
+Unlike extensions, the build configuration for these is generally done using `RELEASE.local` files, which override content specified within their `configure/RELEASE` file. `configure/RELEASE` tells the module where its dependencies live, and it supplies additional configuration flags to the module for build.
+
+In this guide, we will go over building the `asyn` module. Asyn is one of the most commonly used EPICS modules, as it forms the basis for threaded asynchronous device support modules.
+
+## Creating the directories
+
+```sh
+cd /epics
+mkdir modules
+```
+
+## Installing Dependencies (for asyn)
+
+* libtirpc-dev
+
+## Getting the files (for asyn)
+
+```sh
+git clone https://github.com/epics-modules/asyn
+```
+
+## Configuring the build
+
+`cd /epics/modules/asyn`
+
+The first step to building any module is to configure the build using a RELEASE.local file. These are ignored by `.gitignore`, and generally should not be committed to the repository.
+
+Create `configure/RELEASE.local`
+
+Now, open `configure/RELEASE` to see what it contains. For asyn, it looks like this:
+```
+
+```make
+#RELEASE Location of external products
+
+SUPPORT=/corvette/home/epics/devel
+
+# IPAC is only necessary if support for Greensprings IP488 is required
+# IPAC release V2-7 or later is required.
+# It can be obtained here: https://github.com/epics-modules/ipac
+IPAC=$(SUPPORT)/ipac-2-15
+
+# SEQ is required for testIPServer
+# It can be obtained here: https://www-csr.bessy.de/control/SoftDist/sequencer/Manual.html
+SNCSEQ=$(SUPPORT)/seq-2-2-5
+
+# For sCalcout support in asynOctet - applications include asynCalc.dbd
+# It can be obtained here: https://github.com/epics-modules/calc
+CALC=$(SUPPORT)/calc-3-7-3
+
+# If CALC was built with SSCAN support then SSCAN must be defined for testEpicsApp
+# It can be obtained here: https://github.com/epics-modules/sscan
+SSCAN=$(SUPPORT)/sscan-2-11-3
+
+#  EPICS_BASE 3.14.6 or later is required
+#  It can be obtained here: https://github.com/epics-base/epics-base
+EPICS_BASE=/corvette/usr/local/epics-devel/base-7.0.5
+
+-include $(TOP)/../RELEASE.local
+-include $(TOP)/../RELEASE.$(EPICS_HOST_ARCH).local
+-include $(TOP)/configure/RELEASE.local
+```
+
+As you can see, the default `RELEASE` file provided by asyn is very much site-specific to the author's workstation. We'll need to change that.
+
+For this example, we will not be enabling IPAC support, testIPServer or sCalcout support in asynOctet.
+
+Additionally, on modern Linux systems (i.e. Debian 13, Ubuntu 22.04), the RPC library is no longer provided by glibc and is instead in a separate package called tirpc. asyn has a flag we can enable in `RELEASE.local` to enable that, if we're building on a modern system.
+
+Thus, our `RELEASE.local` will look like this:
+```make
+IPAC=
+SNCSEQ=
+SSCAN=
+CALC=
+
+# Enable libtirpc. Required for modern linux
+TIRPC=YES
+
+SUPPORT=/epics/modules
+EPICS_BASE=/epics/base
+
+# If you build and install calc, specify it like this:
+CALC=$(SUPPORT)/calc
+```
+
+## Building
+
+Build, and you're done!
+```
+make
+```

+
+1. Clone EPICS base to your desired directory: `git clone --recursive https://github.com/epics-base/epics-base base` (NOTE: The --recursive flag is necessary here, otherwise you will need to run `git submodule update --init --recursive` later.)
+2. Now you should have `myepics/base`
+
+## Setting up the environment
+
+EPICS requires several environment variables be set. In general, it is recommended to have a script that defines the environment and location for a particular EPICS install. Only a few of these environment variables are required.

+
+With your environment setup, you should now be able to compile EPICS base.

+# EPICS Extensions
+
+Extensions are software packages such as EDM or MEDM that are not designed to be used within IOCs. Building these is a little bit different than modules.
+
+## Getting the files
+
+`cd /epics`
+
+First, we will need to grab the files for the EPICS extensions directory: `git clone --recursive https://github.com/epics-extensions/extensions extensions`
+
+Now, we should have the directory `myepics/extensions` with some content.
+
+`cd /epics/extensions/src`
+
+In the `src` directory within `extensions`, we will place our EPICS extensions. This exact setup is unfortunately required due to how EDM and other extensions have their Makefiles setup.
+
+## EDM
+
+The first major extension we will install is EDM, or "Extensible Display Manager". This is a Motif-based tool for viewing screens. 
+
+### Installing Dependencies
+
+(NOTE: I'm testing all of this on Debian 13, but I am cross-referencing packages with Ubuntu 22.04)
+
+Install the following via APT:
+* libpng-dev
+* libmotif-dev
+* libxm4
+* zlib1g-dev
+* libgif-dev
+* libx11-dev
+* libxtst-dev
+
+
+### Getting the files
+
+`cd /epics/extensions/src`
+
+The files may be obtained from this Github repository: https://github.com/gnartohl/edm
+
+```
+git clone https://github.com/gnartohl/edm
+```
+
+### Building
+
+```sh
+cd /epics/extensions
+make -j$(nproc)
+```
+
+### Running
+
+EDM will search for screens in directories listed in `$EDMDATAFILES` and `$EPICS_DISPLAY_PATH`.
+
+Depending on your system, the default EDM font configuation may not work. It certainly didn't work on my Debian 13 system due to missing fonts that also couldn't be found in the package manager.
+
+To fix this, you will need to modify `edm/setup/fonts.list` to point to courier or some other installed font family. In reality, courier doesn't *actually* need to be installed, EDM will fall back to some other built-in font. Nonetheless, it still requires the fonts.list be filled out.
