+# Frequently Asked Questions
+
+## How do I register for Merlin?
+
+See [Requesting Merlin Access](../merlin7/01-Quick-Start-Guide/requesting-accounts.md).
+
+## How do I get information about downtimes and updates?
+
+See [Get updated through the Merlin User list!](index.md#merlin-user-mailing-list)
+
+## How can I request access to a Merlin project directory?
+
+Merlin projects are placed in the `/data/project` directory. Access to each
+project is controlled by Unix group membership.  If you require access to an
+existing project, please request group membership as described in
+[Requesting Unix Group Membership](../merlin7/01-Quick-Start-Guide/requesting-projects.md#requesting-unix-group-membership).
+
+Your project leader or project colleagues will know what Unix group you should
+belong to. Otherwise, you can check what Unix group is allowed to access that
+project directory (simply run `ls -ltrhd` for the project directory).
+
+## Can I install software myself?
+
+Most software can be installed in user directories without any special
+permissions. We recommend using `/data/user/$USER/bin` for software since home
+directories are fairly small. For software that will be used by multiple
+groups/users you can also [request the admins](index.md) install it as a
+[module](../merlin7/05-Software-Support/pmodules.md).
+
+How to install depends a bit on the software itself. There are three common
+installation procedures:
+
+* *binary distributions*. These are easy; just put them in a directory (eg
+   `/data/user/$USER/bin`) and add that to your PATH.
+* *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.
+!!! note inline end
+    The following is based on `merlin6`, but should still be valid for `merlin7`.
+* *conda environment*. This is now becoming standard for python-based
+   software, including lots of the AI tools. First follow the [initial setup
+   instructions](../merlin6/software-support/python.md#anaconda) to configure conda to
+   use /data/user instead of your home directory. Then you can create
+   environments like:
+
+    ```bash
+    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
+    ```
+
+## Something doesn't work
+
+Check the list of [known problems](known-problems.md) to see if a solution is known.
+If not, please [contact the admins](index.md).
