+## How do I register for merlin?
+
+See [Requesting Accounts](/merlin6/request-account.html).
+
+## Can I install software myself?
+
+Most software can be installed in user directories without any special permissions. We recommend using `/data/user/$USER/bin` for software since home directories are fairly small. For software that will be used by multiple groups/users you can also [request the admins](/merlin6/contact.html) install it as a [module](/merlin6/using-modules.html).
+
+How to install depends a bit on the software itself. There are three common installation procedures:
+
+1. *binary distributions*. These are easy; just put them in a directory (eg `/data/user/$USER/bin`) and add that to your PATH.
+2. *source compilation* using make/cmake/autoconfig/etc. Usually the compilation scripts accept a `--prefix=/data/user/$USER` directory for where to install it. Then they place files under `<prefix>/bin`, `<prefix>/lib`, etc. The exact syntax should be documented in the installation instructions.
+3. *conda environment*. This is now becoming standard for python-based software, including lots of the AI tools. First follow the [initial setup instructions](/merlin6/python.html#anaconda) to configure conda to use /data/user instead of your home directory. Then you can create environments like:
+
+```
+module load anaconda/2019.07
+# if they provide environment.yml
+conda env create -f environment.yml
+
+# or to create manually
+conda create --name myenv python==3.9 ...
+
+conda activate myenv
+```
